The present disclosure relates to the field of displaying, and in particular to a display, a display panel, and an electronic terminal.
As mobile phones develop from a mobile phone having a keypad to a mobile phone having a touch-screen, a screen-to-body ratio of the mobile phone is getting higher and higher. A mobile phone having a full screen has become dominant in the market. The full screen allows a visual area of the mobile phone to increase, and the mobile phone may look more elegant and have a high-tech appearance. Further, a larger-sized screen may be arranged on a front of the mobile phone without changing an area of the front of the mobile phone, and a visual effect of the mobile phone may be increased significantly. In order to meet various requirements of users, at least one corner of a full-screen display panel may be configured to be in an irregular shape. For example, a left-bottom corner and a right-bottom corner of the display panel are configured to be arced. When the irregular-shaped panel is manufactured by a conventional process, wires may be arranged in a non-display region at an outer periphery of the irregular-shaped region. The wires may include a circuit and a wire for driving pixels. To be specific, a data line for providing a data signal and a VDD wire for providing a display signal may be arranged in the non-display region. However, arrangement of these signal lines may be complicated, and therefore, reducing a space occupied by these signal lines may be significantly difficult, and a mobile phone having a narrow edge may not be easily achieved.
According to a first aspect of the present disclosure, a display panel is provided and includes an irregular-shaped region; a plurality of pixels; and a non-display region.

According to a third aspect of the present disclosure, an electronic terminal is provided and includes a driving circuit and the display panel mentioned in the first aspect. The driving circuit is electrically coupled to a data line and the VDD wire of the display panel. The display panel further includes a first electrostatic protection assembly and a second electrostatic protection assembly, the first electrostatic protection assembly is connected to the VDD wire, an orthographic projection of the second electrostatic protection assembly onto the display panel is at least partially overlapped with an orthographic projection of the first electrostatic protection assembly, and an insulation layer is arranged between the first and the second electrostatic protection assemblies.
According to the present disclosure, a display and a display panel are provided. An additional VDD wire may be arranged in an irregular-shaped region. The additional VDD wire may be electrically connected to a pixel in the irregular-shaped region. In this way, a difference between a current received by a pixel in a regular-shaped display region and a current received by the pixel in the irregular-shaped region may be reduced, such that splitting the display region caused by a relatively large difference between a voltage of an impedance of the pixel in the irregular-shaped region and a voltage of an impedance of the pixel in the regular-shaped display region may be avoided. Further, only one VDD wire is arranged in the irregular-shaped region, a space of the non-display region occupied by the VDD wire may be reduced, enabling a narrow edge of the electronic device to be achieved.
According to the present disclosure, one VDD wire may be arranged in an irregular-shaped region. The VDD wire may be connected to a pixel in the irregular-shaped region through a plurality of connection wires. In this way, a difference between a current received by a pixel in a regular-shaped region and a current received by the pixel in the irregular-shaped region may be reduced, such that a difference between a voltage of an impedance of the irregular-shaped region and a voltage of an impedance of the regular-shaped display region may be reduced, and brightness of the irregular-shaped region may not be significantly different from brightness of the regular-shaped display region. Further, only one VDD wire is arranged in the irregular-shaped region, a small portion of the irregular-shaped region may be occupied by the VDD wire, such that a narrow edge of a display panel may be achieved.
Technical solutions of embodiments of the present disclosure may be clearly and comprehensively illustrated by referring to the drawings of the embodiments. It may be understood that, specific embodiments of the present disclosure may be described to explain the present disclosure, but does not limit the scope of the present disclosure. Without a conflict, technical features of various embodiments may be combined. To be noted that, in order to provide a precise description, the drawings show a part of components related to the present disclosure, but do not show all components. Based on embodiments of the present disclosure, any other embodiments obtained by an ordinary skilled person in the art without any creative work should be within the scope of the present disclosure.
As shown in
A plurality of pixels 112 may be arranged in the display region 11, as shown in
At least one corner of the display region 11 may be an arced corner. In other words, the display region 11 may include at least two straight edges adjacent to each other, and an arced angle may be formed between the two adjacent straight edges to serve as the arced corner of the display region. For example, as shown in
At least two adjacent rows of pixels 112 may be arranged in the irregular-shaped display region 111 of the display panel 10, and may have different numbers of pixels 112. For example, as shown in
A driving circuit for driving the pixel 112 to illuminate and a signal wire corresponding to the pixel 112 may be arranged in the non-display region 12. To be specific, the non-display region 12 may include a wiring region.
The wiring region may be adjacent to and fit with the outer periphery of the display region 11 (including a portion of the irregular-shaped region). Signal wires in various types may be arranged in the wiring region. The signal wire may refer to wires in various types for achieving signal transmission. For example, the signal wire may include a scan-drive output line. An end of the scan-drive output line may be connected to a gate driving unit, and the other end of the scan-drive output line may be connected to a pixel circuit. In this way, the scan-drive output line may transmit a scan-drive signal to the pixel 112 connected to the scan-drive output line. As another example, the signal wire may include a VDD wire 121 and a plurality of data lines 122. The plurality of data lines 122 may be arranged in the non-display region 12, and a sub-region within the non-display region 12 occupied by the plurality of signal lines 122 may be referred as a data wiring region 123. As shown in
In the irregular-shaped region, one VDD wire 121 may be arranged. The VDD wire 121 may be arranged at an outer periphery of the data wiring region 123. Further, a plurality of connection wires 124 may be arranged in the non-display region 12. The plurality of connection wires 124 may be connected to the VDD wire 121 and corresponding pixels 112. Each of the plurality of connection wires 124 may cross over the data wiring region 123. For example, orthographic projections of the plurality of connection wires 124 onto the display panel 10 may be located within the data wiring region 123.
Further,
The switch transistor Tsw may be switched based on the scanning pulse transmitted from the scanning line 32, and the switch transistor Tsw may transmit the signal data Vdata from the data line 122 to the driving transistor Tdr. The driving transistor Tdr may be switched based on the data signal Vdata transmitted from the switch transistor Tsw, and the driving transistor Tdr may control a current, which is sent from the VDD wire 121 and may drive the OLED component to illuminate. The capacitor Cst may be connected between a gate electrode and a drain electrode of the driving transistor Tdr. The capacitor Cst may be configured to store a voltage corresponding to the data signal Vdata transmitted to the gate electrode of the driving transistor Tdr, and configured to enable the driving transistor Tdr to be connected through the stored voltage.
The OLED component may at least include: an anode electrode (or a pixel electrode) connected to source electrode of the driving transistor Tdr; an organic light-emitting layer formed on the anode electrode; and a cathode electrode layer formed on the organic light-emitting layer. The OLED component may emit light based on a display signal transmitted from the driving transistor Tdr to display a predefined image.
According to the present disclosure, one VDD wire 121 may be arranged in the irregular-shaped region, a difference between voltages of impedances of the regular-shaped display region and the irregular-shaped region may be reduced, such that a brightness difference between the regular-shaped display region and the irregular-shaped region may not be caused. To be specific, in the present disclosure, the VDD wire 121 may be arranged in the irregular-shaped region and receive the current, a path along which the current flows to reach the pixel in the regular-shaped display region may not be significantly different from a path along which the current flows to reach the pixel in the irregular-shaped region. Therefore, a significant current attenuation may not be caused, i.e., the difference between the current received by the pixel 112 in the irregular-shaped region and the current received by the pixels 112 in the regular-shaped display region may be reduced. The voltage of the impedance of the pixel in the irregular-shaped region may not be significantly different from the voltage of the impedance of the pixel in the regular-shaped display region. Therefore, a brightness difference between the irregular-shaped region and the regular-shaped display region may be reduced, and splitting the display region caused by the relatively large difference between voltages of two impedances of the pixels may be avoided.
In the present disclosure, only one VDD wire 121 may be arranged in the irregular-shaped region. The number of VDD wires may be small, such that an area within the non-display region 12 occupied by the VDD wire may be reduced, and the display panel 10 having the narrow edge may be achieved. Further, the plurality of connection wires 124 may be arranged to cross over the data wiring region 123, and the data wiring region 123 is a region that cannot be omitted from the non-display region 12. Therefore, an additional region to be occupied by the plurality of connection wires 124 may not be required, and the narrow edge of the display panel 10 may not be affected.
In the present disclosure, the VDD wire 121 may be arranged to follow a shape of an edge of the irregular-shaped display region 111, and a shape of the data wiring region 123 may be the same as the shape of the irregular-shaped display region 111. In this way, the wiring region may be close to and fit with the irregular-shaped display region 111 as much as possible, such that the area of the non-display region 12 may be reduced, enabling the display panel 10 having the narrow edge to be achieved easily. For example, in the present disclosure, the VDD wire 121 may be arranged to extend along a shape of an outer edge of the data wiring region 123 as much as possible, such that the display panel 10 may have a most narrow edge. Further, configuration of the signal wires, which include the VDD wire 121 and the plurality of connection wires, may be determined based on the space.
As shown in
In order to reduce the number of connection wires 124 and complexity of the arrangement of the connection wires 124, one connection wire 124 may be connected to a plurality of columns of pixels 112. For example, one connection wire 124 may be connected to two columns of pixels 112. In the irregular-shaped region, the VDD wire 121 may transmit the display signal to each of the plurality of connection wires 124 in the predefined chronological manner, and the display signal may further be transmitted to corresponding connected pixels 112. To be specific, chronological transmission of the display signal may be controlled by a de-multiplexing circuitry. When the de-multiplexing circuitry is connected and control the display signal to be transmitted to a column of pixels 112 connected to one particular 124, the de-multiplexing circuitry may be switched off, and the display signal may not be transmitted to any other columns of pixels 112 connected to the particular wire 124. A working principle of the de-multiplexing circuitry is well-known to any ordinary skilled person in the art, and will not be described in details hereinafter. Of course, one connection wire 124 may be connected to more than two columns of pixels 112.
The connection wire 124 may be a single layer of metal, such as Mo, Cu, and the like, or metal alloy. Alternatively, the connection wire 124 may have a plurality of layers of electric conductive material. In order to control an impedance of a circuitry, material having a relatively low impedance may be used to form the connection wire 124 in the present disclosure.
In one embodiment, the connection wire 124 and the driving transistor Tdr of the pixel 112 may be arranged on a same layer, and may be made of same material. In this way, in the present disclosure, the connection wire 124 and the driving transistor Tdr may be formed by a same process at the same time, such that the number of processes of manufacturing the display panel 10 may not be increased.
As shown in
Further, as shown in
As shown in
The first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 may not be arranged on a same layer. A second insulation layer may be arranged between the first electrostatic protection assembly 21 and the second electrostatic protection assembly 22. In this way, the first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 may be coupled to each other through the second insulation layer therebetween to form a capacitor. The capacitor may be protruded from the VDD wire 121, and a spiking effect may be generated, such that static electricity generated on at least one of the VDD wire 121 and the connection wires 124 may be conducted through the first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 to be released. Therefore, the first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 may be configured to conduct the static electricity generated on at least one of the VDD wire 121 and the connection wires 124 to a region in which the first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 are arranged, and the static electricity may be released therein.
The first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 may be configured to provide electrostatic protection for the display panel 10. The first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 may conduct the static electricity generated on the display panel 10 to the region in which the first electrostatic protection assembly 21 and the second electrostatic protection assembly 22 are arranged, enabling the static electricity to be released therein, such that the static electricity may not harm the display panel 10.
To be specific, the first electrostatic protection assembly 1 may be extended from an end of the VDD wire 121. That is, an extending direction of the electrostatic protection assembly 21 may be parallel to an extending direction of the VDD wire 121, and an extending direction of the second electrostatic protection assembly 22 may be perpendicular to the extending direction of the VDD wire 121.
The first electrostatic protection assembly 21 may be electrically connected to the VDD wire 121, and the first electrostatic protection assembly 21 and the VDD wire 121 may be arranged on the same layer. In the present disclosure, the first electrostatic protection assembly 21 may be a part of the VDD wire 121. In this way, the first electrostatic protection assembly 21 and the VDD wire 121 may be formed by a same process, such that an additional process may not be required. The second electrostatic protection assembly 22 and the plurality of connection wires 124 may preferably be arranged on a same layer, and the second electrostatic protection assembly 22 may be spaced apart from the plurality of connection wires 124. In this way, in the present embodiment, the second electrostatic protection assembly 22 and the plurality of connection wires 124 may be formed by a same process.
It may be understood that, the display panel 10 in the above embodiments may further include other components. For example, the display panel 10 may further include a packaging region. The wiring region may be arranged between the gate driving region and the packaging region. The packaging region may be adjacent to and fit with the wiring region. In this way, the display panel 10 may be protected. To be specific, the packaging region may typically be arranged at an outermost side of the non-display region to isolate the non-display region from water and oxygen, such that the water and the oxygen may not impact the driving circuit and wiring structures inside the display panel 10, and the display panel 10 may work normally.
Further, a type of the display panel 10 may not be limited by the present disclosure. For example, the display panel 10 may be an OLED display panel, a liquid crystal display panel based on low temperature poly-silicon (LTPS), a liquid crystal display panel having polymer-stabilized vertical alignment, a liquid crystal display panel having multi-domain vertical alignment, or a flexible touch-screen display panel. Further, compared to a resistive touch-screen display panel, a capacitive touch-screen display panel may have a longer service life and a high light transmittance, and multi-touch may be performed. The display panel 10 may be a capacitive touch-screen display panel.
The present disclosure may provide a display including a driving circuit and a display panel. The driving circuit may be electrically coupled to a data line of the display panel and the VDD wire. Configuration of the display panel may refer to the display panel described in the above embodiments. Therefore, the display panel in the present embodiment may achieve a same technical effect.
The display includes and is not limited to a mobile terminal, such as a smart mobile phone, a personal digital assistant, and the like, and a wearable device which may be wearable to a user or embedded into clothes, jewelries, and accessories.
The above description may be embodiments of the present disclosure only, and does not limit the scope of the present disclosure. Any equivalent structural or process transformation obtained based on the specification and drawings of the present disclosure, such as combinations of technical features of various embodiments, directly or indirectly applied in other related art, should also be within the scope of the present disclosure.
