DETAILED DESCRIPTION

The following is a detailed description of the electronic device according to the embodiment of the present disclosure. It should be understood that the following description provides many different embodiments for implementing different aspects of some embodiments of the present disclosure. The specific components and arrangements described below are only used to briefly and clearly describe some embodiments of the present disclosure. Of course, these are only examples and not limitations of the present disclosure. In addition, similar and/or corresponding reference numerals may be used to identify similar and/or corresponding elements in different embodiments to clearly describe the present disclosure. However, the use of these similar and/or corresponding reference numerals is only for the purpose of simply and clearly describing some embodiments of the present disclosure, and does not represent any correlation between the different embodiments and/or structures discussed.

It should be understood that relative terms, such as “lower” or “bottom” or “higher” or “top” may be used in the embodiments to describe the relative relationship of one element to another element shown in the figures. It should be understood that if the device in the figures is turned upside down, elements described as being on the “lower” side would then be elements described as being on the “higher” side. The embodiments of the present disclosure can be understood together with the drawings, and the drawings of the present disclosure are also regarded as part of the disclosure description. It should be understood that the drawings of the present disclosure are not drawn to scale and, in fact, the dimensions of elements may be arbitrarily enlarged or reduced in order to clearly illustrate features of the present disclosure.

One structure (or a layer, a component, or a substrate) described in the present disclosure is disposed on/above another structure (or a layer, a component, or a substrate), which may mean that the two structures are adjacent and directly connected, or may mean that two structures are adjacent rather than directly connected. Indirect connection means that there is at least one intermediary structure (or an intermediary layer, an intermediary component, an intermediary base material, an intermediary spacer) between two structures, the lower surface of one structure is adjacent to or directly connected to the upper surface of the intermediary structure, and the upper surface of another structure is adjacent to or directly connected to the lower surface of the intermediary structure. The intermediary structure may be composed of a single-layer or multi-layer physical structure or a non-physical structure, and is not limited. In the present disclosure, when a certain structure is disposed “on” other structures, it may mean that a certain structure is “directly” on other structures, or that a certain structure is “indirectly” on other structures, that is, there is at least one structure sandwiched between a certain structure and other structures.

Furthermore, it should be understood that the ordinals recited in the specification and the claims such as “first”, “second” and so on are intended only to describe the elements claimed and imply or represent neither that the claimed elements have any proceeding ordinals, nor that sequence between one claimed element and another claimed element or between steps of a manufacturing method. The use of these ordinals is merely to differentiate one claimed element having a certain designation from another claimed element having the same designation. The same terms may not be used in the claims and the description. For example, a first element in the description may be a second element in the claims.

In some embodiments of the present disclosure, terms related to joining or connecting, such as “connection”, “interconnection”, etc., unless otherwise defined, may mean that two structures are in direct contact, or may also mean that the two structures are not in direct contact where other structures are located between the two structures. The terms “joint” or “connection” can also include situations where both structures are movable, or where both structures are fixed. In addition, the terms “electrical connection” or “coupling” include any direct and indirect means of electrical connection.

In the present specification, the terms, such as “about”, “substantially”, or “approximately”, are generally interpreted as within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range. Unless otherwise stated, when a value is “in a range from a first value to a second value” or “in a range between a first value and a second value”, the value can be the first value, the second value, or another value between the first value and the second value. In addition, any two values or directions used for comparison may have certain errors. If the first value is equal to the second value, it implies that there may be an error of about 10% between the first value and the second value. If the first direction is perpendicular to the second direction, the angle between the first direction and the second direction may be between 80° and 100°. If the first direction is parallel to the second direction, the angle between the first direction and the second direction may be between 0° and 10°. In the present disclosure, the terms “a given range is a first value to a second value” and “a given range falls within the range of a first value to a second value” mean that the given range includes the first value, the second value, or another value between the first value and the second value.

Furthermore, according to embodiments of the present disclosure, an optical microscopy (OM), a scanning electron microscope (SEM), a film thickness profiler (α-step), an ellipse thickness gauge or other suitable manners may be used to measure the thickness, length, width of each component or the distance and angle between components. Specifically, according to some embodiments, a scanning electron microscope can be used to obtain cross-sectional images of the structure and measure the thickness, length, width of each component, or the distance and angle between components.

Throughout the disclosure and the appended claims of the present disclosure, certain words are used to refer to specific elements. Those skilled in the art should understand that electronic device manufacturers may refer to the same components by different names. The present specification does not intend to distinguish between elements that have the same function but have different names. In the following description and claims, words such as “comprising”, “including”, “containing”, and “having” are open-ended words, so they should be interpreted as meaning “containing but not limited to”. Therefore, when the terms “comprising”, “including”, “containing” and/or “having” are used in the description of the present disclosure, they specify the existence of corresponding features, regions, steps, operations and/or components, but do not exclude the existence of one or more corresponding features, regions, steps, operations and/or components.

The first drive circuit D1, the second drive circuit D and the third drive circuit D3 may be electrically connected to the above-mentioned panels through, for example, a chip on film (COF) package, a chip on glass (COG) package or other manners respectively.

An embodiment will be used as an example to describe in detail the situation in which light passes through an electronic device. However, the present disclosure is not limited to the following situation.

In one embodiment of the present disclosure, as shown in FIG. 2, the electronic device shown in FIG. 1 is used as an example. The first display layer 13 may comprise cholesteric texture liquid crystals that reflect left circularly polarized blue light, the second display layer 23 may comprise cholesteric texture liquid crystals that reflect left circularly polarized green light, and the third display layer 33 may comprise cholesteric texture liquid crystals that reflect left circularly polarized red light; but the present disclosure is not limited thereto. The first photoelectric conversion unit PSC1 may be used at least to absorb blue light (comprising left circularly polarized blue light and right circularly polarized blue light), the second photoelectric conversion unit PSC2 may be used at least to absorb green light (comprising left circularly polarized green light and right circularly polarized green light), the third photoelectric conversion unit PSC3 may be used at least to absorb red light (comprising left circularly polarized red light and right circularly polarized red light), and the another photoelectric conversion unit PSC4 may be used to absorb ultraviolet light and/or infrared light; but the present disclosure is not limited thereto. Even not shown in the electronic device, the electronic device of the present disclosure may comprise a display region (not shown in the figure) and a non-display region (not shown in the figure), the display region refers to the region in the display layer (for example, the first display layer 13, the second display layer 23 and the third display layer 33) that can reflect light. For example, the first display layer 13, the second display layer 23 and the third display layer 33 may comprise, for example, cholesteric texture liquid crystals. When the cholesteric texture liquid crystals corresponding to some pixel regions are in a reflective state, these pixel region can be defined as display regions. The non-display region refers to the region other than the display region. For example, the first display layer 13, the second display layer 23 and the third display layer 33 may comprise, for example, cholesteric texture liquid crystals. When the cholesteric texture liquid crystals corresponding to some pixel regions are in a scattering state (or a transmitting state), these pixel regions can be defined as non-display regions. For convenience of explanation, in FIG. 2, arrows are used to indicate the transmittance or reflection of light, where the transmitting light is indicated by a solid line and the reflected light is indicated by a dotted line. The light on the left side of the line L in FIG. 2 is left circularly polarized light, and the light on the right side of the line L is right circularly polarized light. What is represented by “O” in the table is the wavelength of light that the component can absorb.

As shown in FIG. 2, when ambient light (for example, comprising infrared light, ultraviolet light, red light, green light and/or blue light) irradiates onto the electronic device, the ultraviolet light (UV) and/or the infrared light (IR) may be, for example, at least partially absorbed by the another photoelectric conversion unit PSC4 and converted into electrical energy, and the unabsorbed light (for example, the red light (R), the green light (G) and the blue light (B)) may penetrate through the another photoelectric conversion unit PSC4. Thus, the another photoelectric conversion unit PSC4 can reduce ultraviolet light and/or infrared light from entering the following panels (such as the first panel 1, the second panel 2 and/or the third panel 3), and can be used to reduce the damage caused by ultraviolet light and infrared light to the electronic device.

Next, corresponding to the display region, the first display layer 13 may, for example, reflect the left circularly polarized blue light, and the unreflected light may penetrate through the first display layer 13, wherein the light not reflected by the first display layer 13 may comprise right circularly polarized blue light, green light (including left circularly polarized green light and right circularly polarized green light) and red light (including left circularly polarized red light and right circularly polarized red light). In the non-display region, red light (including left circularly polarized red light and right circularly polarized red light), green light (including left circularly polarized green light and right circularly polarized green light) and blue (including left circularly polarized blue light and right circularly polarized blue light) are not reflected by the first display layer 13, so most of them may penetrate through the first display layer 13. Then, the first photoelectric conversion unit PSC1 may absorb at least part of the blue light (B) and convert it into electrical energy, and the unabsorbed light (for example, red light (R) and green light (G)) may penetrate through the first photoelectric conversion unit PSC1. Thus, the first photoelectric conversion unit PSC1 can be used to improve the purity of reflected light.

Next, in the display region, the second display layer 23 may reflect the left circularly polarized green light, and the unreflected light may penetrate through the second display layer 23, wherein the light not reflected by the second display layer 23 may comprise right circularly polarized green light and red light (including left circularly polarized red light and right circularly polarized red light). In the non-display region, red light (including left circularly polarized red light and right circularly polarized red light) and green light (including left circularly polarized green light and right circularly polarized green light) are not reflected by the second display layer 23, so most of them may penetrate through the second display layer 23. Then, the second photoelectric conversion unit PSC2 may absorb at least part of the green light (G) and convert it into electrical energy, and the light that is not absorbed by the second photoelectric conversion unit PSC2 (for example, red light (R)) may penetrate through the second photoelectric conversion unit PSC2. Thus, the second photoelectric conversion unit PSC2 can be used to improve the purity of reflected light.

Next, in the display region, the third display layer 33 may reflect the left circularly polarized red light, and the unreflected light may penetrate through the third display layer 33, wherein the light that is not reflected by the third display layer 33 may be the right circularly polarized red light. In the non-display region, the red light (including the left circularly polarized red light and the right circularly polarized red light) are not reflected by the third display layer 33, and penetrate through the third display layer 33. Then, the third photoelectric conversion unit PSC3 may absorb at least part of the red light (R) and convert it into electrical energy. Thus, the third photoelectric conversion unit PSC3 can be used to improve the purity of reflected light and may have the same effect to the light absorbing layer AL. In some embodiments, when the above-mentioned light with different wavelengths or light with different colors can be absorbed by different photoelectric conversion units respectively, the light absorbing layer AL can be omitted.

It should be noted that, the above-mentioned first display layer 13, second display layer 23 and third display layer 33 are, for example, respectively used to reflect left circularly polarized light with different wavelengths, but the present disclosure is not limited thereto. In other embodiments (not shown in the figure), the first display layer 13, the second display layer 23 and the third display layer 33 may be used to reflect right circularly polarized light with different wavelengths.

In view above, in the electronic device of one embodiment of the present disclosure, images can be displayed by reflecting light with different colors through the first display layer 13, the second display layer 23, and the third display layer 33, and optionally no additional backlight module is required to form a reflective display device. In other embodiments, for example, the first panel 1 may be provided with a front light guide plate (not shown in the figure) and a light source (not shown in the figure) according to the needs. In addition, in the electronic device of the present disclosure, by using the first photoelectric conversion unit PSC1, the second photoelectric conversion unit PSC2, the third photoelectric conversion unit PSC3 and the another photoelectric conversion unit PSC4, the absorbed light can be converted into electrical energy respectively to achieve the effects of saving power, saving materials or reducing damage to the electronic device.

The “first side” refers to the side of the pixel unit P adjacent to the photoelectric conversion element PSC corresponding thereto. In one embodiment of the present disclosure, the first side S of the pixel unit P may refer to, for example, the upper surface of the corresponding light conversion layer 52; but the present disclosure is not limited thereto.

In one embodiment of the present disclosure, as shown in FIG. 5, the plurality of photoelectric conversion elements PSC may be disposed adjacent to the first side S respectively. For example, the first photoelectric conversion unit PSC1 may be disposed adjacent to the first side S1 of the first pixel unit P1, the second photoelectric conversion unit PSC2 may be disposed adjacent to the first side S2 of the second pixel unit P2, and the third photoelectric conversion unit PSC3 may be disposed adjacent to the first side S3 of the third pixel unit P3; but the present disclosure is not limited thereto.

In the present disclosure, the wavelength ranges of light absorbed by the first photoelectric conversion unit PSC1, the second photoelectric conversion unit PSC2 and the third photoelectric conversion unit PSC3 are different. For example, the first photoelectric conversion unit PSC1 may absorb visible light outside the blue light wavelength range, the second photoelectric conversion unit PSC2 may absorb visible light outside the green light wavelength range, and the third photoelectric conversion unit PSC3 may absorb visible light outside the red light wavelength range; but the present disclosure is not limited thereto. Therefore, the first photoelectric conversion unit PSC1 may allow, for example, most of the blue light to pass through, the second photoelectric conversion unit PSC2 may allow, for example, most of the green light to pass through, and the third photoelectric conversion unit PSC3 may allow, for example, most of the red light to pass through; but the present disclosure is not limited thereto. In the present disclosure, the plurality of photoelectric conversion units PSC (for example, the first photoelectric conversion unit PSC1, the second photoelectric conversion unit PSC2 and the third photoelectric conversion unit PSC3) may have the function of a filter layer, so the filter layer may be optionally omitted in the electronic device to save materials. In addition, in the present disclosure, the plurality of photoelectric conversion units PSC (for example, the first photoelectric conversion unit PSC1, the second photoelectric conversion unit PSC2 and the third photoelectric conversion unit PSC3), for example, may not have polarizing properties. The “not have polarizing properties” means that these photoelectric conversion units PSC do not specifically absorb light in a certain polarization direction, and these photoelectric conversion units PSC (for example, the first photoelectric conversion unit PSC1, the second photoelectric conversion unit PSC2 and the third photoelectric conversion unit PSC3) may absorbed light with multiple polarization directions.

In one embodiment of the present disclosure, as shown in FIG. 5, the electronic device may further comprise a backlight module BL, and the panel 5 is disposed on the backlight module BL. The backlight module BL is used to provide light to the plurality of pixel units P (for example, the first pixel unit P1, the second pixel unit P2 and the third pixel unit P3), so the plurality of pixel units P (for example, the first pixel unit P1, the second pixel unit P2 and the third pixel unit P3) may respectively emit different display lights. More specifically, the backlight module BL may provide light (for example, blue light) to the plurality of pixel units P (for example, the first pixel unit P1, the second pixel unit P2 and the third pixel unit P3), and the light conversion units in the pixel units P may selectively convert the light (for example, blue light) into corresponding color light. For example, the first light conversion unit 521 may, for example, selectively convert the blue light into blue light with other wavelength range, or the first light conversion unit 521 may be replaced by other optical unit (for example, a light scattering layer) and does not have the function of light conversion. The second light conversion unit 522 may, for example, convert the blue light into green light, and the third light conversion unit 523 may convert the blue light into red light. Therefore, the first pixel unit P1, the second pixel unit P2 and the third pixel unit P3 may respectively emit display lights with different colors so that the electronic device can display an image. The aforesaid light conversion units may include quantum dots, phosphors, fluorescence, other suitable light conversion materials, or a combination thereof.

In the present disclosure, the light conversion layer 52 may selectively comprise quantum dot materials. For example, the first light conversion unit 521 may not comprise the quantum dot materials, but the second light conversion unit 522 and the third light conversion unit 523 may respectively comprise the quantum dot materials; but the present disclosure is not limited thereto. In one embodiment of the present disclosure, the first light conversion unit 521 may selectively comprise a scattering material to improve the light emitting efficiency; but the present disclosure is not limited thereto.

For example, the another photoelectric conversion unit PSC′ may absorb at least part of ultraviolet light wavelength, infrared light wavelength or a combination thereof and covert it into electrical energy. The setting of the another photoelectric conversion unit PSC′ can improve the photoelectric conversion effect to achieve power saving, or it can reduce the damage of ultraviolet and/or infrared light to the electronic device and improve the reliability of the electronic device.
