DETAILED DESCRIPTION

The present disclosure may be understood by reference to the following detailed description, taken in conjunction with the embodiments and drawings as described below. It is noted that, for purposes of illustrative clarity and being easily understood by the readers, various drawings of this disclosure may be simplified schematic diagrams that partially illustrate an electronic device; certain components within may not be drawn to scale. In addition, the number and dimension of each component shown in drawings are only illustrative and are not intended to limit the scope of the present disclosure.

Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will understand, electronic equipment manufacturers may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not in function. In the following description and in the claims, the terms “include”, “comprise” and “have” are used in an open-ended fashion, and thus should be interpreted to mean “include, but not limited to . . . ”.

It will be understood that when an element or layer is referred to as being “on” or “connected to” another element or layer, it can be directly on or directly connected to the other element or layer, or intervening elements or layers may be presented. In contrast, when an element is referred to as being “directly on” or “directly connected to” another element or layer, there are no intervening elements or layers presented.

The term “electrically connected” may indicate a direct connection or an indirect connection. Two elements may be electrically connected by directly contacting each other to transmit electrical signals, and the two elements do not have other elements therebetween. Two electrically connected elements may transmit electrical signals via another element bridging therebetween. Elements that are “electrically connected” may also be considered as elements that are “coupled.”

Although terms such as first, second, third, etc., may be used to describe diverse constituent elements, such constituent elements are not limited by the terms. The terms are used only to discriminate a constituent element from other constituent elements in the specification. The claims may not use the same terms, but instead may use the terms first, second, third, etc. with respect to the order in which an element is claimed. Accordingly, in the following description, a first constituent element may be a second constituent element in a claim.

It should be noted that the technical features in different embodiments described in the following description may be replaced, recombined, or mixed with one another to constitute another embodiment without departing from the spirit of the present disclosure.

The sensor unit SU may also include a capacitive sensor, an ultrasonic sensor, an infrared (IR) sensor or other suitable types of sensors.

As shown in FIG. 1, the electronic device 10 may include a demultiplexer (or demux) 106 disposed on the substrate 100 and in the peripheral region PR. The demux 106 may be formed on the substrate 100 using a thin film deposition process, followed by a photolithography process, followed by an etching process, but the present disclosure is not limited thereto. The demux 106 may include a demux unit 102 (which may also be called a first demux unit) and a demux unit 104 (which may also be called a second demux unit), and the demux unit 102 along with the demux unit 104 may be disposed on a side of the active region AR along the second direction D2, but the present disclosure is not limited thereto. In other embodiments, the demux 106 may only include one of the demux unit 102 and the demux unit 104, or the demux unit 102 and the demux unit 104 may be separately disposed on opposite sides of the active region AR along the second direction D2.

The data lines L14 and the sensing lines L24 may be extended from the active region AR to the peripheral region PR, the data lines L14 may be electrically connected to an output end of a corresponding demux unit 102, and the sensing lines L24 may be electrically connected to an output end of a corresponding demux unit 104, but the present disclosure is not limited thereto. In other embodiments, the data lines L14 may be electrically connected to the output end of the corresponding demux unit 102 and the output end of the corresponding demux unit 104, and the sensing lines L24 may be electrically connected to the output end of the corresponding demux unit 102 and the output end of the corresponding demux unit 104. In other embodiments, the demux 106 may only include one of the demux unit 102 and the demux unit 104. The data lines L14 and the sensing lines L24 may be electrically connected to the same demux unit 102 or the same demux unit 104. Or, only the data lines L14 or only the sensing lines L24 may be electrically connected to the demux unit 102 or the demux unit 104; that is to say, the data lines L14 or the sensing lines L24 may not be electrically connected to the demux unit. In this manner, the demux unit 102 may be electrically connected to the display unit DU, and the demux unit 104 may be electrically connected to the sensor unit SU.

On the other hand, the data lines L14 and the sensing lines L24 may be collectively defined as signal lines L1 (which may also be called first signal lines). Therefore, within the peripheral region PR, M signal lines L1 may include M1 data lines L14 and M2 sensing lines L24. “M” is a number of the quantity of the signal lines L1, “M1” is a number of the quantity of the data lines L14, and “M2” is a number of the quantity of the sensing lines L24. The M1 data lines L14 are electrically connected to the display unit DU, and the M2 sensing lines L24 are electrically connected to the sensor unit SU, wherein M1 may be greater than M2, but the present disclosure is not limited thereto. In other embodiments, M1 may be equal to or less than M2. Alternatively, as shown in FIG. 1, the M1 data lines L14 and the M2 sensing lines L24 within the peripheral region PR may be formed of different conductive layers, and insulating layers are present between conductive layers to prevent electrical short or signal interference between signal lines.

As shown in FIG. 1, the electronic device 10 may include a plurality of signal lines L2 disposed on the substrate 100 and within the peripheral region PR. The signal lines L2 may be connected to an input end of the demux unit 102 or an input end of the demux unit 104. The demux unit 102 may be used to electrically connect the data lines L14 to signal lines L2a (a portion of the signal lines L2), such that signals may be inputted to or outputted from the sub-pixels SP of the display unit DU through a path in a sequence of the signal lines L2a—the demux unit 102—the data lines L14. The demux unit 104 may be used to electrically connect the sensing lines L24 to signal lines L2b (another portion of the signal lines L2), such that signals may be inputted to or outputted from the sub-sensor units SSU of the sensor unit SU through a path in a sequence of the signal lines L2b—the demux unit 104—the sensing lines L24, but the present disclosure is not limited thereto. A quantity of the signal lines L2a may be less than a quantity of the data lines L14, and a quantity of the signal lines L2b may be less than a quantity of the sensing lines L24. Therefore, use of the demux unit 102 and/or the demux unit 104 may reduce a quantity of signal lines used to input signals within the peripheral region PR. In other embodiments, a quantity of the data lines L14 may be greater than, equal to or less than a quantity of the sensing lines L24, and a quantity of the signal lines L2a may be greater than, equal to or less than a quantity of the signal lines L2b.

In summary, the demux 106 may be used to electrically connect M signal lines L1 to N signal lines L2 (which may also be called second signal lines), and “N” is a number of the quantity of the signal lines L2. Or, the display unit DU and the sensor unit SU may be electrically connected to N signal lines L2 via M signal lines L1, wherein M may be greater than N. Values of M, N, M1 and M2 may be positive integers (or natural numbers not including zero). In this manner, a quantity of signal lines within the peripheral region PR may be reduced along with a cost of production, time, or a space occupied by the signal lines within the peripheral region PR.

Additionally, the signal lines L2a and the signal lines L2b may be formed of the same conductive layer or different conductive layers, the signal lines L1 connecting the data lines L14 and the signal lines L1 connecting the sensing lines L24 may be formed of the same conductive layer or different conductive layers, the signal lines L1 and the signal lines L2 may be formed of the same conductive layer or different conductive layers, multiple signal lines L1 may be formed of the same conductive layer or different conductive layers, multiple signal lines L2 may be formed of the same conductive layer or different conductive layers, the data lines L14 and the sensing lines L24 may be formed of the same conductive layer or different conductive layers, multiple data lines L14 may be formed of the same conductive layer or different conductive layers, multiple sensing lines L24 may be formed of the same conductive layer or different conductive layers, and multiple scan lines may be formed of the same conductive layer or different conductive layers.

Please refer to FIG. 3, which shows a schematic diagram of a demux unit according to the first embodiment of the present disclosure. As an example, the demux unit 102 shown in FIG. 1 is shown in FIG. 3 as including a plurality of thin film transistors TP. The thin film transistors TP may be arranged into four transistor rows, and the gates of the thin film transistors TP of every transistor row may be electrically connected to a switch signal line LS. For example, a data line L14a, a data line L14e, and a data line L14i may be electrically connected to the thin film transistors TP of a transistor row TR1, a data line L14b, a data line L14f, and a data line L14j may be electrically connected to the thin film transistors TP of a transistor row TR2, a data line L14c, a data line L14g, and a data line L14k may be electrically connected to the thin film transistors TP of a transistor row TR3, and a data line L14d, a data line L14h, and a data line L141 may be electrically connected to the thin film transistors TP of a transistor row TR4.

Using the data line L14a, the data line L14b, the data line L14c, and the data line L14d as an illustrative example, these data lines may be electrically connected to a signal line L2a through thin film transistors TP of different transistor rows, and an end of the signal line L2a may be electrically connected to a bonding pad 110 in order to electrically connect to an output end of a driving unit (for example, an integrated circuit chip, IC). Therefore, by activating thin film transistors TP of different transistor rows, signals to be sent by the signal line L2a may be transmitted to the desired data line L14 as thin film transistors turned on or off, thereby achieving an effect of using one input signal line to correspond to multiple output signal lines. However, a quantity of data lines L14 that may be electrically connected to one signal line L2a is not limited to that shown in FIG. 3. The demux unit 104 may also have the same or similar technical features as those mentioned above; for the sake of brevity, a description of such features is omitted herein.

Please refer to FIG. 1, wherein the electronic device 10 may include a driving unit 108 disposed on the substrate 100 and within the peripheral region PR. The driving unit 108 may include an integrated circuit chip 112 and an integrated circuit chip 114, but a quantity of integrated circuit chips is not limited thereto. In other embodiments, the driving unit 108 may only include the integrated circuit chip 112 or only include the integrated circuit chip 114. In other embodiments, the driving unit 108 may include multiple integrated circuit chips 112 or multiple integrated circuit chips 114. The integrated circuit chip 112 may be electrically connected to the signal lines L2a, and the integrated circuit chip 114 may be electrically connected to the signal line L2b. In other words, the driving unit 108 may be electrically connected to the N signal lines L2. For example, the integrated circuit chip 112 of FIG. 1 may be electrically connected to the bonding pads 110 of FIG. 3, and the integrated circuit chip 114 may also have the same or similar technical features as the integrated circuit chip 112. In such manner, the integrated circuit chip 112 (which may also be called a first driving unit) may be electrically connected to the display unit DU through the signal lines L2a, the demux unit 102 and the data lines L14 (or the signal line L1), whereas the integrated circuit chip 114 (which may also be called a second driving unit) may be electrically connected to the sensor unit SU through the signal lines L2b, the demux unit 104 and the sensing lines L24 (or the signal line L1). The signal lines L2 may for example be formed of the same conductive layer, but the present disclosure is not limited thereto. Electrically connecting the sensor unit SU to the independent integrated circuit chip 114 may increase sensing speed and accuracy. In some embodiments, the integrated circuit chip 112 and the integrated circuit chip 114 may be integrated into one integrated circuit chip.

Additionally, the driving unit 108 may further include at least one gate driver circuit. The gate driver circuit may be an integrated circuit chip, or the gate driver circuit may be formed on the substrate 100 using a thin film deposition process, followed by a photolithography process, and followed by an etching process. As shown in FIG. 1, the driving unit 108 may include a gate driver circuit 1161 and a gate driver circuit 1162, and the active region AR may be disposed between the gate driver circuit 1161 and the gate driver circuit 1162 in the second direction D2, but the present disclosure is not limited thereto. In other embodiments, the driving unit 108 may only include the gate driver circuit 1161 or the gate driver circuit 1162, wherein all the scan lines may be driven from a single side. The gate driver circuit 1161 may be electrically connected to a portion of the display scan lines L12, and the gate driver circuit 1162 may be electrically connected to another portion of the display scan lines L12. Additionally, the gate driver circuit 1161 and the gate driver circuit 1162 may be electrically connected to the driving unit 108 (such as the integrated circuit chip 112), but the present disclosure is not limited thereto.

In other embodiments, the gate driver circuit 1161, the gate driver circuit 1162, the integrated circuit chip 112 or multiple integrated circuit chips 114 may be separately, or at least partially integrated/collected, and then electrically connected to an external control circuit board. In other embodiments, the gate driver circuit 1161, the gate driver circuit 1162, the integrated circuit chip 112 or multiple integrated circuit chips 114 may be located outside of the substrate 100 instead of being disposed on the substrate 100, while using a circuit board to be electrically connected to the bonding pad 110 and provide driving signals.

In some embodiments, the driving unit 108 (such as the integrated circuit chip 112, the integrated circuit chip 114, the gate driver circuit 1161 or the gate driver circuit 1162) may be disposed on the substrate 100 via a chip bonding process. In some embodiments, the driving unit 108 may be electrically connected to the bonding pads of the substrate 100 through a flexible printed circuit (FPC). In some embodiments, the driving unit 108 may be formed on a flexible film (for example, formed as a chip on film, COF) and electrically connected to the bonding pads on the substrate 100.

It is worth noting that, an abovementioned concept of reducing a quantity of signal lines electrically connected to the display unit DU or the sensor unit SU using the demux unit 106 in the peripheral region PR may be applied in the remaining embodiments of the present disclosure. The quantity of the display scan lines electrically connected to the gate driver circuit 1161 or the gate driver circuit 1162 may also be reduced through a demux unit.

The electronic device of the present disclosure is not limited to the abovementioned embodiments; other embodiments will be disclosed in the description below. However, for simplicity and to emphasize differences between each embodiment and the aforementioned embodiments, identical reference signs will be used for identical components and will not be described repeatedly.

Please refer to FIG. 4 and FIG. 5, FIG. 4 is a schematic diagram of an electronic device according to a second embodiment of the present disclosure, and FIG. 5 is a schematic diagram of a demux unit according to the second embodiment of the present disclosure. A difference between the present embodiment and the first embodiment is that the demux 106 of the present embodiment (as shown in FIG. 4) may further include a demux unit 130 and a demux unit 132. The demux unit 130 and the demux unit 132 may be disposed on opposite sides of the active region AR in the first direction D1. For example, the demux unit 130 may be disposed between the gate driver circuit 1161 and the active region AR, and the demux unit 132 may be disposed between the gate driver circuit 1162 and the active region AR, but the present disclosure is not limited thereto.

As shown in FIG. 5, wherein a portion of the demux unit 130 is shown as an illustrative example, the demux unit 130 may include a plurality of thin film transistors TQ that are arranged, for example, as two transistor columns, and the gates of the thin film transistors TQ of each transistor column may be electrically connected to a switch signal line LS.

Additionally, an end of every signal line L3 may be electrically connected to a bonding pad 134, and the bonding pad 134 may be electrically connected to the gate driver circuit 1161 of FIG. 4.

In other embodiments, M3 may be equal to or less than M4. Additionally, the demux unit 130 may be used to electrically connect the abovementioned M signal lines (such as the display scan lines L12 or the sensing scan lines L22) to the N signal lines (such as the signal lines L3), or the display unit DU and the sensor unit SU may both be electrically connected to the N signal lines through the M signal lines, wherein “N” is a number of the quantity of the signal lines, and M is greater than N. The numbers M3 and M4 may be positive integers (or natural numbers not including zero). In this manner, a quantity of signal lines within the peripheral region PR may be reduced along with the cost of production, time, or the space occupied by the signal lines within the peripheral region PR.

In other embodiments, the display unit DU, the demux unit 102 or the integrated circuit chip 112 may also be disposed on the substrate 200; on the other hand, the sensor unit SU, the demux unit 104 or the integrated circuit chip 114 may also be disposed on the substrate 100. In other embodiments, the demux unit 102, the demux unit 104, the sealant 302 or the liquid crystal layer 300 may also be overlapped along a normal direction of the substrate 100.

The substrate 200 may have a surface 2001 and a surface 2002 that are opposite to each other, and the sensor unit SU, the demux unit 104 and the integrated circuit chip 114 of the present embodiment may be disposed on the surface 2001, but the present disclosure is not limited thereto. Additionally, the electronic device 10 may include a spectral modulation structure 146 disposed on the surface 2001. The spectral modulation structure 146 may include a color filter or quantum dot layers to modulate a spectrum of light passing through, in order to achieve an effect of color or brightness adjustment. The spectral modulation structure 146 may also include a black matrix to separate different regions of the spectral modulation structure 146 so as to differentiate the display units, but the present disclosure is not limited thereto. The electronic device 10 may further include a backlight module (not shown) disposed adjacent to the substrate 100 and emitting in a V direction; a greyscale of the brightness of the electronic device 10 may be adjusted through a liquid crystal display unit DU with a polarizer.

Within the peripheral region PR, the data lines L14 on the substrate 100 may extend to the demux unit 102, an end of one of the data lines L14 may be electrically connected to the demux unit 102, and another end of one of the data lines L14 may be electrically connected to the display unit DU (or the sub-pixel SP) inside the active region AR. The demux unit 102 may electrically connect to the integrated circuit chip 112 through the signal lines L2a. For example, an end of one of the signal lines L2a may electrically connect to a bonding pad, and the bonding pad may electrically connect to a bonding pad on the integrated circuit chip 112 through a conductive element 118. The conductive element 118 may, for example, include an anisotropic conductive film (ACF), but the present disclosure is not limited thereto.

On the other hand, the sensing lines L24 on the surface 2001 of the substrate 200 may extend to the demux unit 104. An end of one of the sensing lines L24 may be electrically connected to the demux unit 104, and another end of one of the sensing lines L24 may be electrically connected to the sensor unit SU (or the sub-sensor unit SSU) inside the active region AR. The demux unit 104 may electrically connect to the integrated circuit chip 114 through the signal lines L2b. For example, an end of one of the signal lines L2b may be electrically connected to a bonding pad, and the bonding pad may be electrically connected to a bonding pad of the integrated circuit chip 114 through a conductive element 120. The conductive element 120 may for example include an anisotropic conductive film (ACF), but the present disclosure is not limited thereto.

Within the active region AR, a non-transparent element 122 may be disposed on the substrate 100 and located on a side of each sub-pixel SP; or, the non-transparent element 122 may be disposed between adjacent sub-pixels SP, but the present disclosure is not limited thereto. The non-transparent element 122 may, for example, include the display scan lines L12, the data lines L14, the thin film transistors, or other non-transparent elements or non-transparent layers, but the present disclosure is not limited thereto. When the sensor unit SU is an optical sensor unit, a semiconductor material of a PIN-type diode utilized in the sub-sensor unit SSU may be non-transparent. Therefore, along the V direction, the sub-sensor unit SSU may be disposed on the non-transparent element 122 and not overlap with the sub-pixel SP at an aperture that allows light to pass through, such that light from the backlight module may pass through the sub-pixel SP without being blocked by the sub-sensor unit SSU. By hiding the non-transparent element 122 under the sub-sensor unit SSU, an aperture ratio of the sub-pixel SP and an amount of light passing through may be increased. The direction V may, for example, be a direction perpendicular to a surface of the substrate 100, but the present disclosure is not limited thereto. In some embodiments, the sub-sensor unit SSU may also overlap with the thin film transistor TD of the sub-pixel SP, but not overlap with the electrode ED (such as a pixel electrode) of the sub-pixel SP. Additionally, the thin film transistors TD (not shown in FIG. 8) of the sub-pixels SP may be disposed between the liquid crystal layer 300 and the substrate 100 or between the liquid crystal layer 300 and the substrate 200; the electrodes ED (such as a pixel electrode, not shown in FIG. 8) of the sub-pixels SP may be disposed between the liquid crystal layer 300 and the substrate 100 or between the liquid crystal layer 300 and the substrate 200, but the present disclosure is not limited thereto.

In some embodiments, if the semiconductor material of the PIN-type diode is transparent, the sub-sensor unit SSU may overlap with the sub-pixel SP. In some other embodiments, the sensor unit SU may be a capacitive sensor unit. In such scenarios, since the electrode of the sub-sensor unit SSU may be transparent (with high transmittance) and have minimal effect on the light passing through the sub-pixel SP, the sub-sensor unit SSU may overlap, partially overlap, or not overlap at all with the sub-pixel SP. The sensor unit SU may also include an ultrasonic sensor, an infrared (IR) sensor or other suitable types of sensors. When the sensor unit SU includes IR sensors, the sub-sensor unit SSU may be configured at a position away from metal layers of the electronic device 10, in order to prevent IR sensors being affected by the metal layers.

As shown in FIG. 8, the electronic device 10 may further include an adhesive layer 123, a polarizer 124, an adhesive layer 126 and a cover 128. The adhesive layer 123 may be disposed on the surface 2002 of the substrate 200, the polarizer 124 may be disposed on the adhesive layer 123, the cover 128 may be disposed on an outermost side of the electronic device 10, and the adhesive layer 126 may be disposed between the cover 128 and the polarizer 124, but the present disclosure is not limited thereto.

Additionally, the electronic device 10 may further include a polarizer 142 and an adhesive layer 144. The polarizer 142 and the adhesive layer 144 may be disposed on the surface 1001 of the substrate 100, and the adhesive layer 144 may be disposed between the polarizer 142 and the substrate 100. For example, the polarizer 124 and the polarizer 142 may include linear polarizers, circular polarizers, polarizers with phase retardation layers, polarizers with anti-reflection layers or polarizers with explosion-proof layers, and the cover 128 may include a cover glass, but the present disclosure is not limited thereto.

It is worth noting that, the abovementioned concept of reducing a quantity of signal lines electrically connected to the display unit DU or the sensor unit SU by the demux 106 (such as the demux unit 102 or the demux unit 104) in the peripheral region PR of the first embodiment may also be applied in the present embodiment.

The adhesive layer 144 may be disposed between the polarizer 142 and the protective layer 148, but the present disclosure is not limited thereto. In some embodiments, the protective layer 148 may be omitted, and the adhesive layer 144 may be used to cover the sensor unit SU, the demux unit 104, the integrated circuit chip 114, the sensing lines L24 or the signal lines L2b, but the present disclosure is not limited thereto. In the present embodiment, the sensor unit SU may include ultrasonic sensors or other suitable types of sensors.

It is worth noting that, the abovementioned concept of reducing a quantity of signal lines electrically connected to the display unit DU or the sensor unit SU by the demux 106 (such as the demux unit 102 or the demux unit 104) in the peripheral region PR as mentioned in the first embodiment may also be applied in the present embodiment.

Please refer to FIG. 11, which is a schematic sectional view of an electronic device according to an eighth embodiment of the present disclosure. The present disclosure is different from the fifth embodiment in that the demux unit 102 and the demux unit 104 of the present embodiment may be both disposed on the surface 1002 of the substrate 100. As an example, the sensor unit SU (such as the sub-sensor units SSU), the integrated circuit chip 114, the sensing lines L24, the signal lines L2b or other signal lines (such as the sensing scan lines L22) may also be disposed on the surface 1002 of the substrate 100, but the present disclosure is not limited thereto.

The sub-sensor units SSU, the sensing lines L24 or the sensing scan lines L22 (not shown in FIG. 11) may be disposed on the non-transparent elements 122 (such as the display scan lines L12, the data lines L14 etc.) or the thin film transistors TD of the sub-pixels SP, and the demux unit 104 may be disposed on the demux unit 102, but the present disclosure is not limited thereto. On the other hand, the signal line L2b of the present embodiment may have a folded portion. The folded portion may for example be the conductive line along an inclined surface or the conductive line inside the through hole, wherein a portion of the signal line L2b may be disposed on the signal line L2a, and another portion of the signal line L2b may be disposed on the same surface as the signal line L2a after being folded, but the present disclosure is not limited thereto. Additionally, the signal lines L2a and the signal lines L2b may all be electrically connected to the integrated circuit chip 112 through the conductive element 118; therefore, the electronic device 10 of the present embodiment may omit the integrated circuit chip 114, but the present disclosure is not limited thereto.

Please refer to FIG. 12, which is an enlarged schematic top view of a region Rx in FIG. 11. In the region Rx, when the signal lines L2a and the signal lines L2b extend on the same surface, the signal lines L2a may be separate from the signal lines L2b such that the signal lines L2a and the signal lines L2b may be electrically insulated.

Please refer to FIG. 13, which is a schematic sectional view of an electronic device according to a ninth embodiment of the present disclosure. The present embodiment is different from the eighth embodiment in that the sub-pixels SP of the display unit DU of the present embodiment may include self-emitting organic light-emitting diodes (OLEDs) or inorganic light-emitting diodes (LEDs), and thin film transistors that are electrically connected to the organic light-emitting diodes or inorganic light-emitting diodes.

Additionally, the non-transparent elements 122 of the present embodiment may for example include the display scan lines L12, the data lines L14, common voltage lines, power lines or other non-transparent elements, but the present disclosure is not limited thereto.

Since the semiconductor material of the PIN-type diode utilized in the sub-sensor unit SSU may be non-transparent, the sub-sensor unit SSU should avoid overlapping with a region occupied by the sub-pixels SP having self-emitting diodes in the V direction, so as not to affect the luminous efficacy; the non-transparent element 122 may be disposed next to a side of the diode or disposed under the diode, so as not to affect the luminous efficacy. In some embodiments, if the semiconductor material of the PIN-type diode is transparent, the sub-sensor unit SSU and the sub-pixel SP may be overlapped. In some other embodiments, the sensor unit SU may be a capacitive sensor unit. In such scenarios, since the electrode of the sub-sensor unit SSU may be transparent (with high transmittance) and have minimal effect on the light passing through the sub-pixel SP, the sub-sensor unit SSU may selectively overlap, partially overlap, or not overlap at all with the sub-pixel SP.

The polarizer 124 of the present embodiment may include circular polarizers to provide anti-reflection effects, and the electronic device 10 of the present embodiment may omit the polarizer 142 and the adhesive layer 144 of the eighth embodiment, but the present disclosure is not limited thereto. Furthermore, the signal lines L2a and the signal lines L2b in the region Rx may have the features as shown in FIG. 12; for the sake of brevity, please refer to descriptions in the eighth embodiment, and they are not redundantly described herein.

It is worth noting that, the abovementioned concept of reducing a quantity of signal lines electrically connected to the display unit DU or the sensor unit SU by the demux 106 (such as the demux unit 102 or the demux unit 104) in the peripheral region PR as mentioned in the first embodiment may also be applied in the present embodiment.

In summary, an electronic device of the present disclosure integrates the display unit and the sensor unit inside the active region, wherein the display unit and the sensor unit may both be electrically connected to N signal lines within a peripheral region through M signal lines, and M may be greater than N.
