Description

Technical field

[0001] The present disclosure relates to a display device and a method of driving it, and in particular about a self-powered display device and a method of driving it. Prior technology

[0002] The best time to use self-powered displays is when the brightness of the outdoor sun is sufficient, however the weather cannot be manipulated by humans, so the hunting energy effect of self-powered displays belongs to passive received energy.

[0003] Because the solar module of the self-powered display is at the back of the display panel, when the display screen is dominated by high gray scale (reflective state), the energy of ambient light that can penetrate the display to the solar module is reduced, resulting in a poor hunting effect of the solar module.

[0004] It follows that there is a lack of a display device and its driving method that can balance the display effect and ensure the efficiency of power generation in the market. Contents of the invention

[0005] The purpose of this elucidation is to provide a display device and its driving method, which can effectively improve the overall hunting energy effect of the display device without losing the display effect of the display device by changing all or part of the target pixel from the reflective state to the penetrating state under specific conditions.

Implementation

[0024] Several embodiments of this disclosure will now be described with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the scope of this disclosure. That is, in some embodiments of this disclosure, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simple schematic manner; and repeated elements may be represented by the same number.

[0025] Furthermore, in this document, when a component (or unit or module, etc.) is "connected" to another component, it can mean that the component is directly connected to the other component, or that the component is indirectly connected to the other component, meaning that there is another component between the component and the other component. Only when it is explicitly stated that a component is "directly connected" to another component does it indicate that there is no other component between the component and the other component. The terms "first," "second," and "third" are only used to describe different components and do not limit the components themselves; therefore, "first component" can also be referred to as "second component." Moreover, the combinations of components / units / circuits in this document are not combinations generally known, conventional, or customary in this field. Whether the components / units / circuits themselves are customary cannot be used to determine whether their combination relationships are easily accomplished by someone with ordinary knowledge in the art.

[0026] Please refer to Figures 1 and 2, where Figure 1 is a block diagram illustrating the display device of the first embodiment of this disclosure; and Figure 2 is a schematic diagram illustrating the display panel according to Figure 1. The display device 100 includes a display panel 110, a detection module 120, a processor 130, and a battery module 140. The detection module 120 is electrically connected to the display panel 110 and the battery module 140, and the processor 130 is electrically connected to the display panel 110 and the detection module 120. In addition, the display device 100 further includes a solar module 150, which is electrically connected to the battery module 140 and disposed on one side of the display panel 110 (as shown in Figure 2).

[0027] In the first embodiment, the display panel 110 may be a cholesteric liquid crystal display panel; the detection module 120 may be a combination of a battery detector and a photosensor; the processor 130 may be a microprocessor, a central processing unit (CPU), a mobile device processor, a cloud processor, or other electronic computing processor; the battery module 140 may be a solar cell for photoelectric conversion or a solar cell with a double-sided light-absorbing and light-generating composite material structure, but the present disclosure is not limited thereto.

[0028] Please refer to Figures 2 and 3, where Figure 3 illustrates a schematic diagram of the pixel matrix layers according to Figure 2. The display panel 110 includes a plurality of overlapping pixel matrix layers 111, each pixel matrix layer 111 having a plurality of pixels (e.g., pixels R, G, B, and target pixel K shown in Figure 3). In a first embodiment, the number of pixel matrix layers 111 is three, consisting of a red pixel matrix layer 111r, a green pixel matrix layer 111g, and a blue pixel matrix layer 111b; in other possible embodiments, the number of pixel matrix layers may be two, consisting of a combination of a yellow pixel matrix layer / blue pixel matrix layer, a green pixel matrix layer / magenta pixel matrix layer, or a red pixel matrix layer / cyan pixel matrix layer, but this disclosure is not limited thereto.

[0029] The detection module 120 is used to detect ambient illuminance and battery capacity. The detection module 120 includes a battery capacity detection unit 121 and an ambient light detection unit 122. The battery capacity detection unit 121 is used to detect the battery capacity of the battery module 140. The ambient light detection unit 122 is used to detect ambient illuminance.

[0030] The solar module 150 is used to generate electricity and store it in the battery module 140. In the first embodiment, the solar module 150 may be a photovoltaic power generation device, but this disclosure is not limited thereto.

[0031] Please refer to Figures 1 to 3. The processor 130 obtains the ambient illuminance and power storage from the self-detection module 120, and determines whether to output a penetration control signal to each pixel matrix layer 111 based on the ambient illuminance and power storage. A pixel algorithm is used to divide these pixels into complex matrix regions A, each containing a target pixel K. The processor 130 controls all or part of the complex target pixels K in these matrix regions A to change from a reflective state to a penetration state (i.e., focal conic mode, presenting complete black). In this disclosure, the number of target pixels K in each matrix region A is one, but this disclosure is not limited to this.

[0032] The vertical projection position of matrix region A in each pixel matrix layer 111 corresponds to the vertical projection position of the target pixel K in each matrix region A. For example, as shown in Figure 3, the vertical projection position of each matrix region A in the red pixel matrix layer 111r corresponds to the vertical projection position of each matrix region A in the green pixel matrix layer 111g and the blue pixel matrix layer 111b; and the vertical projection position of the target pixel K in each matrix region A in the red pixel matrix layer 111r, green pixel matrix layer 111g, and blue pixel matrix layer 111b is also the same.

[0033] Each matrix region A is at least a 2x2 matrix arrangement, and the target pixels K in any two adjacent matrix regions A are not adjacent to each other. In the first embodiment, the matrix region A is a 2x2 matrix arrangement, but this disclosure is not limited to this. In other possible embodiments, the matrix region can be a calculable arrangement such as a 1x2 matrix arrangement, a 2x3 matrix arrangement, a 3x3 matrix arrangement, or a 4x4 matrix arrangement.

[0034] Furthermore, the processor 130 includes outputting a color control signal to each pixel matrix layer 111, so that the pixels of each pixel matrix layer 111 are colored according to the color control signal corresponding to their respective pixel matrix layer 111. Moreover, when the target pixel K changes from a reflective state to a transmissive state, the processor 130 further includes outputting a color control signal to the surrounding pixels in the matrix region A other than the target pixel K (e.g., pixels R, G, and B shown in Figure 3), to adjust the reflectivity of the surrounding pixels, thereby compensating for the reduced reflectivity caused by the target pixel K changing to a transmissive state.

[0035] In detail, the processor 130 simultaneously checks whether the ambient illuminance is greater than a preset illuminance and whether the stored power is less than a preset power to generate a judgment result. When the ambient illuminance is greater than the preset illuminance (when the ambient light is sufficient), or when the stored power is less than the preset power (when the battery module 140 has insufficient power and the charging efficiency of the solar module 150 needs to be increased), the judgment result is "yes". In this case, the processor 130 outputs a transmission state control signal to each pixel matrix layer 111 to change the target pixel K from a reflective state to a transmission state. Then, it outputs a color control signal to the surrounding pixels outside the target pixel K in the matrix region A to adjust the reflectivity of the surrounding pixels and maintain the original image viewing quality.

[0036] When the ambient illuminance is less than or equal to the preset illuminance (when the ambient light is insufficient) and the stored power is greater than or equal to the preset power (when the battery module 140 has sufficient power), the judgment result is negative. The processor 130 then outputs a color control signal to each pixel matrix layer 111, so that the pixels of each pixel matrix layer 111 directly display colors according to the color control signal.

[0037] In this way, by conditionally judging, the target pixel K in matrix region A is converted to a transparent state, so that ambient light can penetrate the display panel 110 to the solar module 150, thereby increasing the power generation of the solar module 150 locally and improving the overall energy harvesting effect.

[0038] It should be noted that, in the first embodiment, the processor 130 outputs a penetration control signal based on either sufficient ambient light or insufficient battery charge in the battery module 140, but this disclosure is not limited to this. In other possible embodiments, the processor may use both sufficient ambient light and insufficient battery charge in the battery module 140 as the determination condition, or set corresponding conditions as needed.

[0039] Furthermore, in order to balance the display effect of the display panel 110 with the power generation improvement effect of the solar module 150, the processor 130 uses a pass-through control signal to arrange the target pixels K of any two adjacent matrix regions A in a staggered manner. The staggered manner can be one of clockwise stagger, counterclockwise stagger, horizontal stagger, vertical stagger, or interval stagger, but this disclosure is not limited to this.

[0040] For details, please refer to Figures 1, 2, 4A, and 4B, where Figure 4A is a schematic diagram illustrating the staggered arrangement of target pixels in the second embodiment of the present disclosure; and Figure 4B is a schematic diagram illustrating the pixel matrix layer arranged in the staggered manner according to Figure 4A in the second embodiment. As shown in Figure 4A, in the second embodiment, the target pixel K is staggered in a clockwise direction. The processor 130 can use a penetration state control signal to first define the first pixel from top to bottom in the rightmost row of matrix region A as the starting target pixel K, and then define the target pixels K in adjacent matrix regions A in a clockwise direction (arrow order in the figure).

[0041] To further explain, as shown in Figure 4B, the pixel matrix layer 111 contains three matrix regions A1, A2, and A3. The processor 130 first defines the first pixel in the rightmost row from top to bottom in matrix region A1 as the initial target pixel K. Then, according to the clockwise offset method shown in Figure 4A (arrow order in the figure), the second pixel in the rightmost row from top to bottom in the adjacent matrix region A2 is defined as the target pixel K, and the third pixel in the rightmost row from top to bottom in the adjacent matrix region A3 is defined as the target pixel K. This process continues, and in the case of multiple matrix regions A, the target pixels K of any two adjacent matrix regions A are offset clockwise.

[0042] Please refer to Figures 1, 2, and 5 through 8, where Figure 5 is a schematic diagram illustrating the staggered arrangement of target pixels in the third embodiment of the present disclosure; Figure 6 is a schematic diagram illustrating the staggered arrangement of target pixels in the fourth embodiment of the present disclosure; Figure 7 is a schematic diagram illustrating the staggered arrangement of target pixels in the fifth embodiment of the present disclosure; and Figure 8 is a schematic diagram illustrating the staggered arrangement of target pixels in the sixth embodiment of the present disclosure.

[0043] As shown in Figure 5, in the third embodiment, the target pixel K is misaligned in a counterclockwise direction. The processor 130 can use the penetration state control signal to first define the first pixel in the rightmost row from top to bottom in the matrix region A as the starting target pixel K, and then define the target pixels K in the adjacent matrix regions A in a counterclockwise direction (arrow order in the figure).

[0044] As shown in Figure 6, in the fourth embodiment, the target pixel K is misaligned in a horizontal manner. The processor 130 can use the penetration state control signal to first define the first pixel in the leftmost row from top to bottom in the matrix region A as the starting target pixel K, and then define the target pixels K in the adjacent matrix regions A in the horizontal direction (arrow order in the figure).

[0045] As shown in Figure 7, in the fifth embodiment, the target pixel K is misaligned vertically. The processor 130 can use the penetration state control signal to first define the first pixel in the leftmost row from top to bottom in the matrix region A as the starting target pixel K, and then define the target pixels K in the adjacent matrix regions A in the vertical direction (arrow order in the figure).

[0046] As shown in Figure 8, in the sixth embodiment, the misalignment of the target pixel K is an interval misalignment. The processor 130 can use the penetration state control signal to first define the first pixel in the leftmost row from top to bottom in the matrix region A as the starting target pixel K, and then define the target pixels K in the adjacent matrix regions A in an interval manner (in the order of the arrows in the figure).

[0047] This avoids the display effect being affected by the periodic arrangement of adjacent matrix areas A where all target pixels K are located in the same position, thereby achieving the goal of balancing the display effect of the display panel 110 and the power generation improvement effect of the solar module 150.

[0048] Please refer to Figures 1 to 3 and Figure 9, where Figure 9 is a flowchart illustrating the display device driving method of the seventh embodiment of this disclosure. The display device 100 is configured to implement the display device driving method 200. It should be noted that the display device driving method 200 of this disclosure is not limited to implementation through the display device 100 of this disclosure.

[0049] The display device driving method 200 includes steps 210, 220, 230, 240, 250, and 260. In step 210, the detection module 120 detects the ambient illuminance and the stored power. In step 220, the processor 130 determines, based on the ambient illuminance and the stored power, whether to output a transmittance control signal to the complex pixel matrix layer 111 of the display panel 110, wherein each pixel matrix layer 111 contains a complex number of pixels (e.g., pixels R, G, B, and the target pixel K shown in Figure 3). The processor 130 simultaneously confirms whether the ambient illuminance is greater than a preset illuminance and whether the stored power is less than a preset power to generate a determination result.

[0050] In step 230, using the penetration state control signal output by processor 130, the pixel matrix layer 111 is divided into complex matrix regions A using a pixel algorithm. Each matrix region A contains a target pixel K, and processor 130 controls all or part of the complex target pixels K in these matrix regions A to change from a reflection state to a penetration state. Processor 130 uses the penetration state control signal to arrange the target pixels K of any two adjacent matrix regions A in a staggered manner. The staggered manner can be one of clockwise staggered, counterclockwise staggered, horizontal staggered, vertical staggered, or interval staggered, but this disclosure is not limited to these.

[0051] In step 240, the processor 130 outputs a color control signal to each pixel matrix layer 111 so that the pixels of the pixel matrix layer 111 are colored according to the color control signal corresponding to the pixel matrix layer 111 in which they are located.

[0052] In detail, in step 220, when the ambient illuminance is greater than the preset illuminance (when the ambient light is sufficient), or when the stored power is less than the preset power (when the battery module 140 is under-stored and the charging efficiency of the solar module 150 needs to be increased), the judgment result is yes, and step 230 is executed to output a penetration state control signal to the pixel matrix layer 111. After the target pixel K changes from the reflection state to the penetration state, the reflectivity of the surrounding pixels is adjusted.

[0053] When the ambient illuminance is less than or equal to the preset illuminance (when the ambient light is insufficient) and the stored power is greater than or equal to the preset power (when the battery module 140 has sufficient power), the judgment result is negative. Then, step 240 is executed to output a color control signal to the pixel matrix layer 111 and display colors according to the color control signal.

[0054] In step 250, the processor 130 determines whether to perform color compensation on the output screen based on the color algorithm.

[0055] In step 260, the processor 130 outputs color control signals to the peripheral pixels (e.g., pixels R, G and B shown in Figure 3) in matrix region A other than the target pixel K, in order to adjust the reflectivity of the peripheral pixels and thereby compensate for the reduced reflectivity caused by the target pixel K turning into a transmissive state.

[0056] In detail, in step 250, when the processor 130 determines, based on the color algorithm, that color compensation needs to be output for the surrounding pixels in matrix region A other than the target pixel K, it will continue to execute step 260 to output a color control signal to compensate for the reduced reflectivity of the target pixel.

[0057] When the processor 130 determines, based on the color algorithm, that it is not necessary to output color compensation for the surrounding pixels in matrix region A other than the target pixel K, it continues to execute step 240 to output a color control signal to the pixel matrix layer 111 and display the color according to the color control signal.

[0058] By controlling the target pixel K to change from a reflective state to a transmissive state under specific conditions, the energy harvesting effect of the solar module 150 can be effectively improved without losing the display effect of the display panel 110.

[0059] As can be seen from the above embodiments, the present disclosure has the following advantages: First, by converting the target pixels in the matrix area into a transparent state through conditional judgment, the power generation of the solar module is locally enhanced, thereby improving the overall energy harvesting effect. Second, by using the transparent state control signal to arrange the target pixels of any two adjacent matrix areas in a staggered manner, it is possible to avoid the target pixels from being arranged in a periodic manner, such as moiré patterns, affecting the screen display effect, thereby achieving the goal of balancing the display effect of the display panel and the power generation enhancement effect of the solar module.

[0060] Although the present disclosure has been presented above with reference to embodiments, it is not intended to limit the scope of the present disclosure. Anyone skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims.
