Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a dual-unit display architecture and a dimming display method. Background Technology

[0002] With the continuous development of LCD technology, Dual Cell display architecture has become an important solution for improving image quality.

[0003] Dual-cell display architectures typically achieve pixel-level local dimming by stacking two layers of panels: a Sub-Cell (dimming unit) and a Main Cell (main display unit). However, this existing Dual Cell technology still has significant shortcomings in terms of dimming precision. On the one hand, because the pixel size of the Sub-Cell layer is the same as or larger than that of the Main Cell layer, the dimming area of ​​the Sub-Cell layer is too large, making it difficult to achieve precise pixel-level brightness control. On the other hand, due to the limitation of the number of grayscale voltages in the Sub-Cell layer, the brightness adjustment levels of the Sub-Cell layer are limited, which can easily lead to obvious brightness jumps when displaying gradual changes in images, severely restricting the image quality performance of display devices using this dual-cell display architecture.

[0004] Therefore, improving the dimming accuracy of dual-unit display architecture to enhance the image quality of display devices is a pressing technical problem that needs to be solved. Summary of the Invention

[0008] In one embodiment, the number of data lines in the dimming unit layer is the same as the number of data lines in the main display unit layer, and the number of scan lines in the dimming unit layer is twice the number of scan lines in the main display unit layer; In the main display unit layer, each scan line is electrically connected to each of the color pixels in the corresponding row, and each data line is electrically connected to each of the color pixels in the corresponding column; In the dimming unit layer, the target column sub-pixel group and the neighboring row sub-pixel group in each pixel dimming unit are electrically connected to the same data line. All pixel dimming units in each row are driven by two scan lines. The target row sub-pixel group in all pixel dimming units in each row is electrically connected to one of the two scan lines, and the neighboring row sub-pixel group in all pixel dimming units in each row is electrically connected to the other scan line. In each of the pixel dimming units, a sub-pixel located in the i-th row and at least one adjacent sub-pixel in the same row constitute the target row sub-pixel group; a sub-pixel located in the (i+1)-th row and at least one adjacent sub-pixel in the same row constitute the neighbor row sub-pixel group; a sub-pixel located in the j-th column and at least one adjacent sub-pixel in the same column constitute the target column sub-pixel group; and a sub-pixel located in the (j+1)-th column and at least one adjacent sub-pixel in the same column constitute the neighbor column sub-pixel group.

[0009] Furthermore, to achieve the above objectives, this application also provides a dimming display method, which is applied to the dual-unit display architecture described in any of the preceding claims, and the dimming display method includes: Based on the brightness display level of the input screen, determine the sub-pixel illumination mode of the brightness adjustment unit; Based on the timing drive signals from the control terminals on both sides of the brightness adjustment unit in the sub-pixel illumination mode, the control data line is used to charge each sub-pixel in the corresponding pixel dimming unit in a time-division manner; wherein, The brightness display levels include a first brightness level, a second brightness level, a third brightness level, and a fourth brightness level. The timing drive signal includes a first time-division signal from a first time-division control terminal and a second time-division signal from a second time-division control terminal. The pixel dimming unit includes a target row sub-pixel group, a neighboring row sub-pixel group, a target column sub-pixel group, and a neighboring column sub-pixel group. The target row sub-pixel group is composed of a sub-pixel located in the i-th row and at least one adjacent sub-pixel in the same row. The neighboring row sub-pixel group is composed of a sub-pixel located in the j-th column and at least one adjacent sub-pixel in the same column.

[0010] In one embodiment, the dimming display method further includes: Take a sub-sub-pixel in the i-th row of the target row sub-pixel group as the first sub-sub-pixel, and take a sub-sub-pixel in the same row as the first sub-pixel in the target row sub-pixel group as the second sub-sub-pixel; The sub-sub-pixel located in the (i+1)th row of the neighboring row sub-pixel group is designated as the third sub-sub-pixel, and the sub-sub-pixel in the same row as the third sub-pixel in the neighboring row sub-pixel group is designated as the fourth sub-sub-pixel.

[0011] In one embodiment, when the sub-sub-pixel illumination mode is a single sub-sub-pixel cyclic illumination mode of the first brightness level, the step of controlling the data line to perform time-division charging to each sub-sub-pixel in the corresponding pixel dimming unit according to the timing drive signal of the two control terminals of the brightness adjustment unit in the sub-sub-pixel illumination mode includes: When scanning the target row sub-pixel group in the first frame period, the data line electrically connected to the brightness adjustment unit is enabled to provide a bright signal, and the first time-division signal is activated synchronously while the second time-division signal is kept in the off state, so as to fill the first sub-pixel with the bright signal; Until the neighboring row sub-pixel group is scanned, the data line is enabled to switch the bright signal to a dark signal, and the second time-division signal is activated simultaneously while maintaining the activation state of the first time-division signal. The dark signal is then filled into the third sub-pixel and the fourth sub-pixel respectively, so as to obtain the first sub-pixel after being filled with the bright signal within the first frame period. During the second frame period, the first time-division signal is turned off while the second time-division signal remains active, and the bright signal provided by the data line when scanning the target row sub-pixel group is filled into the second sub-pixel; During the third frame period, the bright signal provided by the data line when scanning the target row sub-pixel group is switched to the dark signal.

When scanning the neighboring row sub-pixel group during the fourth frame period, the bright signal provided by the data line to the neighboring row sub-pixel group during the third frame period is filled into the fourth sub-pixel based on the activated first time-division signal and the deactivated second time-division signal.

[0012] In one embodiment, when the sub-pixel illumination mode is the horizontal alternating illumination mode of the second brightness level, the step of controlling the data line to perform time-division charging to each sub-pixel in the corresponding pixel dimming unit according to the timing drive signal of the two control terminals of the brightness adjustment unit in the sub-pixel illumination mode includes: During the first frame period, the data line electrically connected to the brightness adjustment unit is enabled to provide a dark signal, and when the first time-division signal and the second time-division signal are activated, the target row sub-pixel group and the neighboring row sub-pixel group are scanned synchronously to simultaneously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the dark signal; During the second frame period, the data line is enabled to switch the dark signal to a bright signal, and when the first time-division signal and the second time-division signal are activated, the target row sub-pixel group and the neighboring row sub-pixel group are scanned synchronously to simultaneously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the bright signal. During the third frame period, the data line is enabled to switch the bright signal to the dark signal, and when the first time-division signal and the second time-division signal are activated, the target row sub-pixel group and the neighboring row sub-pixel group are scanned simultaneously to simultaneously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the dark signal. During the fourth frame period, the data line is enabled to switch the dark signal to a bright signal, and when the first time-division signal and the second time-division signal are activated, the target row sub-pixel group and the neighboring row sub-pixel group are scanned synchronously to simultaneously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the bright signal.

[0013] In one embodiment, when the sub-sub-pixel illumination mode is the single sub-sub-pixel non-illuminated mode of the third brightness level, the step of controlling the data line to perform time-division charging to each sub-sub-pixel in the corresponding pixel dimming unit according to the timing drive signal of the two control terminals of the brightness adjustment unit in the sub-sub-pixel illumination mode includes: In the single sub-pixel unlit mode, a bright signal is provided that is electrically connected to the brightness adjustment unit; When scanning the target row sub-pixel group in the first frame period, the first time-division signal is turned off and the second time-division signal is activated, enabling the first sub-sub-pixel to not be lit when the second sub-sub-pixel is filled with the bright signal. When scanning the neighboring row sub-pixel group, the first time-division signal is activated, and the bright signal is synchronously filled into the third sub-sub-pixel and the fourth sub-sub-pixel based on the activated first time-division signal and the second time-division signal. When scanning the target row sub-pixel group in the second frame period, the first time-division signal is activated and the second time-division signal is turned off, enabling the second sub-sub-pixel to not be lit when the first sub-sub-pixel is filled with the bright signal, and when scanning the neighboring row sub-pixel group, the bright signal is synchronously filled into the third sub-sub-pixel and the fourth sub-sub-pixel based on the activated first time-division signal and the second time-division signal. When scanning the target row sub-pixel group in the third frame period, the first time-division signal and the second time-division signal are activated, and the bright signal is synchronously filled into the first sub-sub-pixel and the second sub-sub-pixel. When scanning the neighboring row sub-pixel group, the third sub-sub-pixel is enabled not to be lit when the fourth sub-sub-pixel is filled with the bright signal based on the activated first time-division signal and the deactivated second time-division signal. When scanning the target row sub-pixel group during the fourth frame period, the first time-division signal and the second time-division signal are activated to synchronously fill the first sub-sub-pixel and the second sub-sub-pixel with the bright signal. When scanning the neighboring row sub-pixel group, the fourth sub-sub-pixel is enabled not to be lit when the third sub-sub-pixel is filled with the bright signal based on the closed first time-division signal and the activated second time-division signal.

[0014] In one embodiment, when the sub-sub-pixel illumination mode is the sub-sub-pixel full illumination mode of the fourth brightness level, the step of controlling the data line to perform time-division charging to each sub-sub-pixel in the corresponding pixel dimming unit according to the timing drive signal of the two control terminals of the brightness adjustment unit in the sub-sub-pixel illumination mode includes: When the enable data line provides a light signal, the first time-division signal and the second time-division signal are activated simultaneously. When scanning the target row sub-pixel group in each frame period, the bright signal is filled into the first sub-pixel and the second sub-pixel based on the activated first time-division signal and the second time-division signal, and when scanning the neighboring row sub-pixel group, the bright signal is filled into the third sub-pixel and the fourth sub-pixel based on the activated first time-division signal and the second time-division signal.

[0015] In one embodiment, the dimming display method includes: Based on the display information of the input screen, determine the light-dark transition edge region, and determine the sub-pixel positions that need to be compensated in the light-dark transition edge region; Determine the brightness values ​​of the bright and dark areas adjacent to the sub-pixel position, and use the median brightness value between the bright and dark areas as the compensation brightness display data; When scanning reaches the row where the sub-pixel is located, the data line is controlled to provide the compensation brightness display data based on the charging timing signal mapped by the sub-pixel position to perform charging compensation for the sub-pixel at the sub-pixel position.

[0016] The dual-unit display architecture proposed in this application is applied to display devices, effectively solving the technical defect of insufficient dimming accuracy in existing Dual Cell technology. Specifically, this application sets the main display unit layer to multiple arrayed color pixels, and in the dimming unit layer, each color pixel is provided with a pixel dimming unit composed of N sub-pixels. This allows the miniaturization of sub-pixels to reduce the minimum control area of ​​each pixel dimming unit to 1 / (N*N) of the corresponding color pixel, where N is a natural number greater than 1, thereby improving dimming precision. Next, this application sets the two side paths of each brightness adjustment unit to be electrically connected to a data line and each sub-pixel in the corresponding pixel dimming unit, respectively. The two side control terminals of each brightness adjustment unit are electrically connected to a first time-division control terminal and a second time-division control terminal, respectively. This allows the brightness adjustment unit to perform precise time-division charging control to the arrayed sub-pixels in the corresponding pixel dimming unit based on the timing drive signals (i.e., the first time-division signal from the first time-division control terminal and the second time-division signal from the second time-division control terminal) input to its two side control terminals, in conjunction with the data line. This expands the limited grayscale levels in the traditional Dual Cell architecture to a sub-pixel-level progressive adjustment, breaking through the limitations of traditional Dual Cell architecture. The Cell architecture limits the dimming levels by the number of grayscale voltages and effectively solves the problem of brightness jumps in gradient images, thereby significantly improving the image quality of display devices.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0026] As display panel technology has developed to its current state, LCD (Liquid Crystal Display) technology has become quite mature. In order to stand out in the highly competitive market, panel manufacturers have put forward many innovative solutions in terms of improving contrast and optimizing grayscale performance.

[0027] Traditional LCD technology is limited by issues such as backlight modulation precision and liquid crystal response speed, making it difficult to achieve ultra-high contrast and smooth grayscale transitions. Although Mini-LED (Mini Light Emitting Diode) technology achieves precise local dimming through high-density LED (Light Emitting Diode) arrays, the heat dissipation challenges posed by tens of thousands of LEDs, along with high production and maintenance costs, have hindered its widespread application. In contrast, Dual Cell technology uses two TFT-LCD (Thin Film Transistor Liquid Crystal Display) panels stacked together. The lower Sub Cell achieves pixel-level local dimming, while the upper Main Cell handles color rendering. This achieves dimming capabilities comparable to Mini-LEDs at tens of millions of dimming zones while avoiding the heat dissipation and cost issues of Mini-LEDs.

[0028] However, this existing Dual Cell technology still has significant drawbacks: on the one hand, the turning delay of liquid crystal molecules causes a timing mismatch between the Sub Cell and the Main Cell in dynamic images, resulting in motion blur; on the other hand, limited by the pixel size of the dimming unit and the number of grayscale voltages, the existing Dual Cell architecture is difficult to achieve true pixel-level dimming precision, which restricts further improvement in image quality.

[0029] To address the technical problem of poor dimming accuracy in existing Dual Cell architectures and further improve the image quality of display devices, this application provides a dual-unit display architecture and a dimming display method.

[0030] This application provides a dual-unit display architecture, referring to... Figure 1 As shown, Figure 1 This is a structural block diagram of a first embodiment of the dual-unit display architecture of this application. The dual-unit display architecture includes: The main display unit layer 100 consists of multiple arrayed color pixels.

[0031] In this embodiment, the application sets up a main display unit layer 100 formed by multiple color pixels arranged in an array, so that the main display unit layer 100 can serve as a normal liquid crystal display layer to present color images.

[0032] It should be noted that, Figure 1 The colored pixels arranged from left to right as shown can be red pixels, green pixels, and blue pixels. The above color order arrangement is only one feasible implementation method of this application, and this application does not make any restrictions here.

[0033] A dimming unit layer 200 is stacked vertically with the main display unit layer 100. The dimming unit layer 200 includes pixel dimming units 21 corresponding to each color pixel. Each pixel dimming unit 21 is composed of N sub-pixels distributed in an array. The size of each sub-pixel is 1 / (N*N) of the pixel size of the corresponding color pixel, where N is a natural number greater than 1.

[0034] In this embodiment, the dimming unit layer 200 and the main display unit layer 100 are stacked vertically, such that each pixel dimming unit 21 in the dimming unit layer 200 overlaps with the corresponding color pixel. Furthermore, each pixel dimming unit 21 is composed of N sub-pixels distributed in an array, thereby reducing the minimum control area of ​​each pixel dimming unit 21 to 1 / (N*N) of the corresponding color pixel, so as to realize pixel-level dimming control of the corresponding color pixel in the dimming unit layer 200.

[0035] It should be noted that the vertical stacking of the dimming unit layer 200 and the main display unit layer 100 can be understood as two independent dimming unit layers 200 and the main display unit layer 100 being stacked in parallel, and the stacking thickness of the dimming unit layer 200 and the main display unit layer 100 being perpendicular to the display surface, thereby enabling the brightness adjustment of the dimming unit layer 200 to achieve perfect coordination with the color rendering of the main display unit layer 100.

[0036] In specific implementation, refer to Figure 2 In this application, a main display unit layer 100 is stacked on the upper surface of the dimming unit layer 200, and a backlight lamp bead layer 300 is stacked on the lower surface of the dimming unit layer 200. Furthermore, to increase the uniformity of edge light, a backlight strip 400 can be attached to the thickness side of the backlight lamp bead layer. In other words, this application... Figure 2 The multi-layer stacked design shown allows the backlight source emitted by the backlight bead layer 300 to be projected onto the main display unit layer 100 for color rendering after the brightness is adjusted by the dimming unit layer 200, so as to present a color picture with uniform brightness and good color effect on the main display unit layer 100.

[0037] A brightness adjustment unit 10 is provided, which corresponds one-to-one with the pixel dimming unit 21. Each brightness adjustment unit 10 has a data line Sj electrically connected to one of the sub-pixels in the corresponding pixel dimming unit 21 at both ends. Each brightness adjustment unit 10 has a first time-division control terminal C1 and a second time-division control terminal C2 electrically connected to one of the control terminals on both ends. The data line Sj is the data line matched to the corresponding pixel dimming unit 21. The brightness adjustment unit 10 is configured to control the data line Sj to perform time-division charging of the sub-pixels in the corresponding pixel dimming unit 21 according to the timing drive signal input to the control terminals on both ends.

[0038] In this embodiment, each brightness adjustment unit 10 is electrically connected to a data line Sj and each sub-pixel in the corresponding pixel dimming unit 21 on both sides of the access terminal. Each brightness adjustment unit 10 is also electrically connected to a first time-division control terminal C1 and a second time-division control terminal C2 on both sides of the control terminal. This allows the brightness adjustment unit 10 to perform precise time-division charging control to the sub-pixels distributed in the array in the corresponding pixel dimming unit 21, based on the timing drive signals (i.e., the first time-division signal of the first time-division control terminal C1 and the second time-division signal of the second time-division control terminal C2) input to its control terminals on both sides, in conjunction with the data line Sj. This expands the limited grayscale levels in the traditional Dual Cell architecture to a sub-pixel-level progressive adjustment, breaking through the limitation of the number of grayscale voltages on the dimming levels in the traditional Dual Cell architecture, and effectively solving the brightness jump problem in gradient images, thereby significantly improving the image quality of the display device.

[0039] Furthermore, in some other feasible embodiments, reference is made to... Figure 3 The brightness adjustment unit 10 includes a first switch T1 and a second switch T2; the gate control terminal of the first switch T1 forms one of the two control terminals and is electrically connected to the first time-division control terminal C1, and the gate control terminal of the second switch T2 forms the other control terminal and is electrically connected to the second time-division control terminal C2; the first path terminal of the first switch T1 and the first path terminal of the second switch T2 form one of the two path terminals, wherein the first path terminal of the first switch T1 is electrically connected to the target column sub-pixel group, and the first path terminal of the second switch T2 is electrically connected to the neighboring column sub-pixel group, the target column sub-pixel group is each of the sub-sub-pixels on the target column, and the neighboring column sub-pixel group is each of the sub-sub-pixels on the next column of the target column; the second path terminal of the first switch T1 and the second path terminal of the second switch T2 form the other path terminal and are electrically connected to the data line Sj.

[0040] In this embodiment, refer to Figure 3 The brightness adjustment unit 10 in this application adopts a dual thin-film transistor architecture (i.e., the first switch T1 and the second switch T2), which enables a single data line (i.e., data line Sj) to perform time-division charging on the target column sub-pixel group and the neighboring column sub-pixel group in each pixel dimming unit 21 through the alternating conduction of the first time-division control terminal C1 and the second time-division control terminal C2. This not only breaks through the limitation of the number of gray level voltages on the dimming level in the traditional Dual Cell architecture, achieving more precise brightness control, but also significantly improves the dimming accuracy of the dual-unit display architecture without increasing the cost of the data line by connecting the second path terminal of the first switch T1 and the second path terminal of the second switch T2 to the same data line Sj.

[0041] It should be noted that the first switching transistor and the second switching transistor are the same thin-film transistor, MOSFET or other components with switching characteristics, and this application does not impose any restrictions.

[0042] Furthermore, in some feasible embodiments, reference is made to Figure 4 The number of data lines in the dimming unit layer 200 is the same as the number of data lines in the main display unit layer 100, and the number of scan lines in the dimming unit layer 200 is twice the number of scan lines in the main display unit layer 100.

[0043] In this embodiment, Figure 4 The number of data lines in dimming unit layer 200 shown in (b) is... Figure 4In (a) shown in the diagram, the number of data lines in the main display unit layer 100 remains the same, thus avoiding increased cost and wiring complexity due to adding more data lines. Simultaneously, without increasing the number of pins on the data driver chip, the data is driven by GOA (Gate Driver on Array). Figure 4 The number of scan lines in the dimming unit layer 200 shown in (b) is set to Figure 4 The main display unit layer 100 shown in (a) is twice the size of the main display unit layer 100. While reducing the cost risks and wiring complexity caused by increasing the number of data lines, the dimming unit layer 200 provides double the line control precision for the pixel dimming unit 21 corresponding to each color pixel. This lays a crucial hardware foundation for the subsequent realization of sub-pixel level fine dimming, thereby achieving a significant leap in display performance under the premise of controllable cost.

[0044] It should be noted that, Figure 4 In (a), Sn_i represents the data line in the main display unit layer 100. Figure 4 In (a), Gn_i represents the scan line in the main display unit layer 100; Figure 4 In (b), Si represents the data line in the dimming unit layer 200. Figure 4 In (b), Gn_i represents the scan line in the dimming unit layer 200.

[0045] In the main display unit layer 100, each scan line is electrically connected to each of the color pixels in the corresponding row, and each data line is electrically connected to each of the color pixels in the corresponding column.

[0046] In this embodiment, refer to Figure 4 In (a) of the main display unit layer 100, a mature and efficient traditional matrix driving method is adopted. That is, each scan line is electrically connected to all color pixels in the corresponding row and is responsible for selecting the pixels in that row. At the same time, each data line is electrically connected to each color pixel in the corresponding column and is responsible for writing the data voltage signal into the selected color pixel. This ensures the stable display of the main display unit layer 100 and provides a stable and reliable color image rendering foundation for the dual-unit display architecture.

[0047] It should be noted that, Figure 4 In (a), “R0, G0 and B0” represent red, green and blue colored pixels, respectively; Figure 4 The Ti shown represents a thin-film transistor.

[0048] In the dimming unit layer 200, the target column sub-pixel group and the neighboring row sub-pixel group in each pixel dimming unit 21 are electrically connected to the same data line. All pixel dimming units 21 in each row are driven by two scan lines. The target row sub-pixel group in each pixel dimming unit 21 in each row is electrically connected to one of the two scan lines, and the neighboring row sub-pixel group in each pixel dimming unit 21 in each row is electrically connected to the other of the two scan lines. In each pixel dimming unit 21, a sub-pixel in the i-th row and at least one adjacent sub-pixel in the same row constitute the target row sub-pixel group; a sub-pixel in the (i+1)-th row and at least one adjacent sub-pixel in the same row constitute the neighboring row sub-pixel group; a sub-pixel in the j-th column and at least one adjacent sub-pixel in the same column constitute the target column sub-pixel group; and a sub-pixel in the (j+1)-th column and at least one adjacent sub-pixel in the same column constitute the neighboring column sub-pixel group.

[0049] In this embodiment, refer to Figure 4 The driving architecture of the dimming unit layer 200 shown in (b) allows the same data line to electrically connect the target column sub-pixel group and the neighboring row sub-pixel group within a pixel dimming unit 21. This enables sub-subpixels in different columns within the same pixel dimming unit 21 to share the same data line, significantly reducing the total number of data lines required and avoiding increased costs, decreased yield, and signal interference caused by increased wiring density. Simultaneously, each pixel dimming row's pixel dimming unit 21 consists of two scan lines (i.e., Figure 4 As shown in (b), scan lines Gi and Gi+1 drive the pixel dimming row together. Each pixel dimming row physically includes closely adjacent rows i and i+1. Each pixel dimming unit 21 has a target row sub-pixel group and a neighboring row sub-pixel group in rows i and i+1, respectively. For example, in the pixel dimming unit 21 of each pixel dimming row, scan line Gi is electrically connected to all target row sub-pixel groups in row i, and scan line Gi+1 is electrically connected to all neighboring row sub-pixel groups in row i+1. The dual scan line design achieves separate and precise control of the sub-subpixels in adjacent rows of each pixel dimming row. It also combines the data lines shared by sub-subpixels in different columns of the same pixel dimming unit 21 to achieve independent addressing capability of sub-subpixels, providing a stable and reliable hardware structure for subsequent implementation of complex time-division charging control.

[0050] In a specific embodiment, within a pixel dimming unit 21, the target row sub-pixel group consists of a sub-pixel located in the i-th row and at least one adjacent sub-pixel in the same row; correspondingly, the neighboring row sub-pixel group consists of a sub-pixel in the (i+1)-th row immediately below it and at least one adjacent sub-pixel in the same row. In the column direction, the target column sub-pixel group consists of a sub-pixel in the j-th column and at least one adjacent sub-pixel in the same column, while the neighboring column sub-pixel group consists of a sub-pixel in the (j+1)-th column and at least one adjacent sub-pixel in the same column.

[0051] For example, refer to Figure 4 In (b), the pixel dimming unit consists of N*N sub-pixels arranged in an array. When N equals 2, this application divides each pixel dimming unit 21 into four sub-pixels arranged in a matrix and adopts an innovative row-column cross-grouping driving method to achieve more refined display control. Specifically, the four sub-pixels construct a target row sub-pixel group, a neighboring row sub-pixel group, a target column sub-pixel group, and a neighboring column sub-pixel group through specific row-column combinations. This allows a single data line to drive sub-pixels at different positions in a spatially alternating manner, which not only significantly improves the local dimming accuracy and makes the brightness adjustment more delicate and smooth, but also effectively improves the edge display effect through the optimized sub-pixel arrangement. At the same time, the row-column cross-grouping strategy realizes intelligent allocation of driving signals at the hardware level, which maintains the simplicity of the circuit structure and provides a basic support for high-quality image display.

[0052] It should be noted that, referring to Figure 4 In (a) and (b), when the color pixel is a red pixel R0, the pixel dimming unit 21 corresponding to the red pixel R0 is composed of a first sub-sub-pixel representing red R1, a second sub-sub-pixel representing red R2, a third sub-sub-pixel representing red R3, and a fourth sub-sub-pixel representing red R4; wherein the first sub-sub-pixel representing red R1 and the second sub-sub-pixel representing red R2 form a target row sub-pixel group, the fourth sub-sub-pixel representing red R4 and the third sub-sub-pixel representing red R3 form a neighboring row sub-pixel group; the first sub-sub-pixel representing red R1 and the fourth sub-sub-pixel representing red R4 form a target column sub-pixel group; and the second sub-sub-pixel representing red R2 and the third sub-sub-pixel representing red R3 form a neighboring column sub-pixel group.

Furthermore, the pixel dimming unit 21 corresponding to the green pixel G0 can be...

[0055] In summary, the dual-unit display architecture proposed in this application, when applied to a display device, effectively solves the technical defect of insufficient dimming accuracy in existing DualCell technology. Specifically, the main display unit layer 100 of this application consists of multiple arrayed color pixels, and in the dimming unit layer 200, a pixel dimming unit 21 composed of N sub-pixels is set for each color pixel. This allows the miniaturization of sub-pixels to reduce the minimum control area of ​​each pixel dimming unit 21 to 1 / (N*N) of the corresponding color pixel, where N is a natural number greater than 1, thereby improving dimming accuracy. Furthermore, each brightness adjustment unit 10 is electrically connected to a data line Sj and each sub-pixel in the corresponding pixel dimming unit 21 at both ends. Each brightness adjustment unit 10 is electrically connected to a first time-division control terminal C1 and a second time-division control terminal C2 on both sides of its control terminals. This allows the brightness adjustment unit 10 to perform precise time-division charging control to the sub-sub-pixels distributed in the array of the corresponding pixel dimming unit 21 in conjunction with the data line Sj, based on the timing drive signals (i.e., the first time-division signal of the first time-division control terminal C1 and the second time-division signal of the second time-division control terminal C2) input to its two control terminals. This expands the limited grayscale levels in the traditional Dual Cell architecture to a sub-pixel-level progressive adjustment, breaking through the limitation of the number of grayscale voltages on the dimming levels in the traditional Dual Cell architecture, and effectively solving the problem of brightness jump in the gradient picture, thereby significantly improving the picture quality performance of the display device.

[0056] Furthermore, based on the first embodiment of the dual-unit display architecture of this application, a second embodiment of the dimming display method of this application is proposed.

[0057] The dimming display method of this application is applied to the dual-unit display architecture of any of the above. The dimming display method of this application is executed by a display device applied to the dual-unit display architecture. The dimming display method of this application includes the following implementation steps S10 to S20.

[0058] Step S10: Determine the sub-pixel illumination mode of the brightness adjustment unit 10 based on the brightness display level of the input screen.

[0059] In this embodiment, the brightness adjustment unit 10 is composed of N*N (N*N*N=4) sub-pixels distributed in an array. This application uses the N*N*N=4 sub-pixels in each brightness adjustment unit 10 to perform brightness and darkness superposition, thereby increasing the dimming quantity of the dimming unit layer 200. Thus, while maintaining the original 256 levels of hardware grayscale voltage of the dimming unit layer 200, the equivalent 1024 levels of dimming accuracy are achieved by utilizing the persistence of vision of the human eye. Specifically, based on the brightness level of the input screen, a combination lighting mode (i.e., sub-sub-pixel lighting mode) of N*N=4 sub-pixels within a 4-frame cycle is dynamically selected in the same brightness adjustment unit 10 to control the alternating lighting of different numbers of sub-subpixels in the brightness adjustment unit 10. The equivalent brightness superposition is achieved by utilizing the persistence of vision of the human eye, expanding the original 256 gray levels to 1024 levels. Thus, while keeping the number of hardware gray level voltages unchanged, the brightness adjustment unit 10, composed of N*N=4 sub-subpixels distributed in an array, effectively solves the brightness jump problem caused by insufficient voltage resolution in the traditional Dual Cell architecture, and significantly improves the dimming accuracy of the dual-unit display architecture.

[0060] It should be noted that the brightness display levels may include the first brightness level, the second brightness level, the third brightness level, and the fourth brightness level.

[0061] For example, when the brightness display level is the first brightness level L0, the sub-pixel lighting mode is a single sub-pixel cyclic lighting mode; when the brightness display level is the second brightness level L1, the sub-pixel lighting mode is a horizontal alternating lighting mode; when the brightness display level is the third brightness level L2, the sub-pixel lighting mode is a single sub-pixel not lit mode; and when the brightness display level is the fourth brightness level L3, the sub-pixel lighting mode is a sub-pixel fully lit mode.

[0062] Step S20: Based on the timing drive signals of the two control terminals of the brightness adjustment unit 10 in the sub-pixel illumination mode, control the data line Sj to perform time-division charging to each sub-pixel in the corresponding pixel dimming unit 21; wherein, the brightness display level includes a first brightness level, a second brightness level, a third brightness level, and a fourth brightness level, the timing drive signals include a first time-division signal of the first time-division control terminal C1 and a second time-division signal of the second time-division control terminal C2, the pixel dimming unit 21 includes a target row sub-pixel group and a neighboring row sub-pixel group, the target row sub-pixel group includes a first sub-pixel and a second sub-pixel, the neighboring row sub-pixel group includes a third sub-pixel and a fourth sub-pixel, and the neighboring row sub-pixel group is the next row sub-pixel group after the target row sub-pixel group.

[0063] In this embodiment, the first time-division control terminal C1 and the second time-division control terminal C2 are connected to the control terminals on both sides of the brightness adjustment unit 10 to generate corresponding timing drive signals in each sub-sub-pixel lighting mode. Within a single frame period, when scanning the target row sub-pixel group and the neighboring row sub-pixel group line by line, the data line Sj is controlled to charge the first sub-sub-pixel and the second sub-sub-pixel respectively based on the corresponding timing drive signals (i.e., the combination of the first time-division signal and the second time-division signal). This row-column cross-time-division charging mechanism ensures that each sub-sub-pixel can obtain precise brightness control. Furthermore, the complexity of the dual-unit display architecture is significantly reduced by data line multiplexing. Ultimately, a more delicate brightness transition and higher dimming accuracy are achieved without changing the hardware resources.

[0064] It should be noted that data line Sj provides the same brightness signal to each sub-pixel in the same row. This brightness signal can be a bright signal or a dark signal. A dark signal can be understood as a brightness signal that the sub-pixel does not receive from data line Sj. When there are multiple data lines Sj, they can be represented by data lines S1, S2, S3, ..., and Sn, i.e., j = 1, 2, 3, ..., n.

[0065] The first time-division signal provided by the first time-division control terminal C1 is set to control the on / off state of the target column pixel group and the data line Sj; the second time-division signal provided by the second time-division control terminal C2 is set to control the on / off state of the neighboring column pixel group and the data line Sj.

[0066] Furthermore, in some feasible embodiments, the dimming display method may also include implementing steps S100 to S200.

[0067] Step S100: Take a sub-sub-pixel located in the i-th row of the target row sub-pixel group as the first sub-sub-pixel, and take a sub-sub-pixel in the same row as the first sub-pixel in the target row sub-pixel group as the second sub-sub-pixel.

[0068] In this embodiment, refer to Figure 5 The pixel dimming unit consists of N*N sub-subpixels distributed in an array. When N equals 2, if a sub-subpixel in the i-th row of the target row sub-pixel group is the first sub-subpixel (i.e., ... Figure 5 (R1, G1, or B1 in the first sub-sub-pixel), and the sub-sub-pixel adjacent to the first sub-sub-pixel in the same row as the second sub-sub-pixel (i.e. Figure 5 The data structure (R2, G2, or B2) can be used to decompose each sub-sub-pixel in the target row sub-pixel group into individuals with clear identification and independent control logic, thus laying a stable and reliable data structure foundation for achieving sub-pixel-level fine dimming in the target row sub-pixel group.

[0069] Step S200: Take a sub-sub-pixel in the (i+1)th row of the neighboring row sub-pixel group as the third sub-sub-pixel, and take a sub-sub-pixel in the same row as the third sub-pixel in the neighboring row sub-pixel group as the fourth sub-sub-pixel.

[0070] In this embodiment, refer to Figure 5 This application uses the same logic as step S100 to take a sub-sub-pixel located in the (i+1)th row of the neighboring row sub-pixel group as the third sub-sub-pixel (i.e. Figure 5 (R3, G3, or B3 in the image), and take a sub-sub-pixel in the neighboring row sub-pixel group that is adjacent to the third sub-pixel in the same row as the fourth sub-sub-pixel (i.e., R3, G3, or B3 in the image), and take a sub-sub-pixel in the neighboring row sub-pixel group that is adjacent to the third sub-pixel in the same row as the fourth sub-sub-pixel (i Figure 5 The R4, G4, or B4 values ​​in the image, combined with step S100, complete a comprehensive and structured identification of a pixel dimming unit 21 (containing four sub-pixels). By assigning clear and independent identities to the four sub-pixels (first sub-pixel, second sub-pixel, third sub-pixel, and fourth sub-pixel), collaborative or differentiated control can be performed on these four sub-pixels. This allows the display device to flexibly determine which sub-pixels in the pixel dimming unit are lit within a specific frame period and with what brightness combination, based on the final brightness display level. Thus, with only 256 hardware grayscale voltage levels for each color pixel, precise spatiotemporal brightness combination control is performed on the four sub-pixels in the pixel dimming unit 21 corresponding to each color pixel, ultimately synthesizing up to 1024 equivalent intermediate dimming levels. This greatly improves the overall uniformity and detail of the image and significantly enhances the dimming accuracy. For example, when displaying large areas of gradient colors or low-brightness scenes, the brightness transition is extremely smooth, completely avoiding the color banding phenomenon caused by insufficient dimming levels in traditional solutions; at the same time, it can accurately reproduce tiny details in extremely dark or extremely bright scenes, making the display effect more delicate and realistic, and significantly enhancing the visual experience.

[0071] Furthermore, in some other feasible embodiments, reference is made to... Figure 4 as well as Figure 6 When the sub-pixel illumination mode is the single sub-pixel cyclic illumination mode of the first brightness level, the above step S20: according to the timing drive signal of the two control terminals of the brightness adjustment unit 10 in the sub-pixel illumination mode, the data line Sj is controlled to charge each sub-pixel in the corresponding pixel dimming unit 21 in a time-division manner, and may also include implementing steps S201 to S205.

[0072] Step S201: When scanning the target row sub-pixel group during the first frame period, enable the data line Sj electrically connected to the brightness adjustment unit 21 to provide a bright signal, and simultaneously activate the first time-division signal while maintaining the cutoff state of the second time-division signal, so as to fill the first sub-pixel with the bright signal.

[0073] In this embodiment, refer to Figure 4 as well as Figure 6 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 6 In (a) shown in the first brightness level L0 single sub-subpixel cyclic illumination mode, the first sub-subpixel in the pixel dimming unit 21 is illuminated individually in 4 frame cycles (i.e., Figure 6 (a) shows R1, G1, and B1), and the second sub-pixel (i.e. Figure 6 (a) shows R2, G2, and B2), and the third sub-pixel (i.e. Figure 6 (a) shows R3, G3, and B3) and the fourth sub-pixel (i.e. Figure 6 (See (a) for R4, G4, and B4). For details, refer to... Figure 6 In (b) of the first frame period, when the row containing the target sub-pixel group is scanned, the data line Sj outputs a bright signal, that is, the data to be filled into the first sub-sub-pixel and the second sub-sub-pixel is the bright signal. At this time, the first time-division signal is activated synchronously and the second time-division signal is kept in the off state. Thus, the first switch T1 can be enabled by the activated first time-division signal to conduct the electrical connection from the data line Sj to the first sub-sub-pixel, and only the bright signal is filled into the first sub-sub-pixel. The second switch T2 is also enabled by the off (closed) second time-division signal to disconnect the electrical connection from the data line Sj to the second sub-sub-pixel, so as to ensure that the first sub-sub-pixel is lit when the row containing the target sub-pixel group is scanned in the first frame period.

[0074] It should be noted that when the first sub-pixel refers to the red R1 sub-pixel, the green G1 sub-pixel, and the blue B1 sub-pixel, the data line Sj of the red R1 sub-pixel is data line S1, the data line S2 of the green G1 sub-pixel is data line S2, and the data line Sj of the blue B1 sub-pixel is data line S3.

[0075] Figure 6 The signal Gi shown in (b) can represent the scan signal that drives the scanning of all target row sub-pixel groups in the i-th row. Figure 6 The signal Gi+1 shown in (b) is a scan signal that drives the scanning of all neighboring row subpixel groups on row i+1.

[0076] Figure 6The black rectangle shown in (b) represents the dark signal. Figure 6 The blank rectangle shown in (b) represents the bright signal that has been filled into the sub-pixel. Figure 6 The dotted rectangle shown in (b) represents the bright signal of the sub-pixel that has not been filled.

[0077] Figure 6 The signal waveform shown in (b) is the dimming signal waveform of the red sub-pixel in the single sub-pixel cyclic lighting mode of the brightness adjustment unit 10. In addition, the dimming signal waveforms of the green / blue sub-pixels in the single sub-pixel cyclic lighting mode are the same as the dimming signal waveform of the red sub-pixel, which will not be described in detail here.

[0078] Step S202: Until the neighboring row sub-pixel group is scanned, enable the data line Sj to switch the bright signal to a dark signal, and simultaneously activate the second time-division signal while maintaining the activation state of the first time-division signal. Fill the third sub-pixel and the fourth sub-pixel with the dark signal respectively, so as to obtain the first sub-pixel after filling with the bright signal within the first frame period.

[0079] In this embodiment, refer to Figure 4 as well as Figure 6 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 6 In the first frame period shown in (a), when the first sub-pixel (i.e. Figure 6 As shown in (a), after R1, G1, and B1 are filled with a bright signal, the scan signal switches from signal Gi to signal Gi+1. At this time, data line Sj switches the bright signal to a dark signal and simultaneously activates the second time-division signal while maintaining the activation state of the first time-division signal. This allows the dark signal to be synchronously filled into the third sub-pixel (i.e., ...) through the conducting first switch transistor T1 and second switch transistor T2. Figure 6 (a) shows R3, G3, and B3) and the fourth sub-pixel (i.e. Figure 6 (as shown in (a) R4, G4, and B4), thus ensuring that only the first sub-pixel (i.e., ...) is illuminated during the first frame period. Figure 6 As shown in (a) (R1, G1, and B1), it saves 1 / 4 of the scanning time.

[0080] Step S203: During the second frame period, turn off the first time-division signal and maintain the active state of the second time-division signal, and fill the second sub-sub-pixel with the bright signal provided by the data line Sj when scanning the target row sub-pixel group.

[0081] In this embodiment, refer to Figure 4 as well as Figure 6The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) can save scanning time for the (i+1)th row (i.e., the (Gi+1)th row) because the brightness signal provided by the data line Sj to the neighboring row sub-pixel group in the (i+1)th row (i.e., the (Gi)th row) is still a dark signal. Figure 6 As shown in (a) of the diagram, data is refreshed only for the target row subpixel group in row Gi during the second frame period, thus reducing the scan time by half. Specifically, in Figure 6 In the second frame period shown in (a), when the target row sub-pixel group is scanned by signal Gi (i.e., row Gi), the first time-division signal is turned off while the second time-division signal remains active, thereby achieving the purpose of activating only the second time-division signal. Based on the activated second time-division signal, the second switch T2 is enabled to conduct the data line Sj to the second sub-pixel (i.e., row Gi). Figure 6 (as shown in (a) R2, G2 and B2), thus ensuring that only the second sub-pixel is lit during the second frame period.

[0082] Step S204: During the third frame period, the bright signal provided by the data line Sj when scanning the target row sub-pixel group is switched to the dark signal. After the dark signal is filled into the first sub-pixel and the second sub-pixel based on the first time-division signal and the second time-division signal that are synchronously activated, the dark signal provided by the data line Sj when scanning the neighboring row sub-pixel group is switched to the bright signal, and the bright signal is filled into the third sub-pixel based on the activated second time-division signal and the deactivated first time-division signal.

[0083] In this embodiment, refer to Figure 4 as well as Figure 6 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 6 During the third frame period shown in (a), when scanning the row containing the target row sub-pixel group (i.e., row Gi) based on signal Gi, data line Sj outputs a dark signal and simultaneously activates the first time-division signal and the second time-division signal so that the dark signal is synchronously charged into the first sub-pixel (i.e., row Gi) through the turned-on first switch T1 and second switch T2. Figure 6 R1, G1, and B1) and the second sub-pixel (i.e. Figure 6As shown in (a), R2, G2, and B2 can save 1 / 4 of the scanning time. After the first and second sub-sub-pixels are filled with dark signals, the scanning signal is switched from signal Gi to signal Gi+1 to scan the row where the neighboring row sub-pixel group is located (i.e., row Gi+1). At this time, the data line Sj switches the dark signal to a bright signal, that is, the data to be filled into the third and fourth sub-sub-pixels is the bright signal, and the activated first time-division signal is turned off, only maintaining the activation state of the second time-division signal, so that the second switch T2, driven by the activated second time-division signal, conducts the connection between the data line Sj and the third sub-sub-pixel, and fills the third sub-sub-pixel (i.e., the bright signal is filled only into the third sub-sub-pixel) Figure 6 (as shown in (a) R3, G3 and B3), thus ensuring that only the third sub-pixel is lit during the third frame period.

[0084] Step S205: When scanning the neighboring row sub-pixel group in the fourth frame period, the bright signal provided by the data line Sj to the neighboring row sub-pixel group in the third frame period is filled into the fourth sub-pixel based on the activated first time-division signal and the deactivated second time-division signal.

[0085] In this embodiment, refer to Figure 4 as well as Figure 6 The dimming signal waveform shown in (b) shows that since the brightness signal provided by data line Sj in the row containing the target row sub-pixel group (i.e., row Gi) is still a dark signal, the scanning time of row Gi can be saved. Data is only refreshed in the row containing the neighboring row sub-pixel group (i.e., row Gi+1), thereby reducing the scanning time by 1 / 2. Specifically, in Figure 6 As shown in (a) of the fourth frame period, when only the row containing the neighboring row sub-pixel group (i.e., row Gi+1) is scanned by signal Gi+1, the second time-division signal is turned off and the first time-division signal is activated, so that the first switch T1, driven by the activated first time-division signal, conducts the connection between the data line Sj and the fourth sub-pixel, and the bright signal is only charged into the fourth sub-pixel (i.e., row Gi+1). Figure 6 (R4, G4, and B4 shown in (a)) thus ensures that only the fourth sub-pixel is lit during the fourth frame period.

[0086] In summary, the dual-display driver architecture configured in this application improves dimming accuracy while, based on the aforementioned steps S201 to S205, operating in single sub-pixel cyclic illumination mode according to... Figure 6 The dimming signal waveform shown in (b) can save 1.5 times the scanning time of the standard line.

[0087] Furthermore, in some feasible embodiments, reference is made to Figure 4 as well as Figure 7When the sub-pixel illumination mode is the horizontal alternating illumination mode of the second brightness level, the above step S20: according to the timing drive signal of the two control terminals of the brightness adjustment unit 10 in the sub-pixel illumination mode, the data line Sj is controlled to charge each sub-pixel in the corresponding pixel dimming unit 21 in a time-division manner, and may also include implementing steps A10 to A40.

[0088] Step A10: During the first frame period, enable the data line Sj electrically connected to the brightness adjustment unit 21 to provide a dark signal, and when the first time-division signal and the second time-division signal are activated, synchronously scan the target row sub-pixel group and the neighboring row sub-pixel group to synchronously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the dark signal.

[0089] In this embodiment, refer to Figure 4 as well as Figure 7 The dimming signal waveform shown in (b) represents N sub-pixels (i.e., the first to fourth sub-pixels) in the pixel dimming unit 21, which is illuminated at intervals of adjacent frames within a 4-frame cycle in the horizontal alternating illumination mode of the second brightness level L1. Specifically, based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 7 As shown in (a) of the diagram, during the first frame period, the enabled data line Sj provides a dark signal, and because the luminance data provided by the data line Sj in the row containing the neighboring row sub-pixel group (i.e., row Gi+1) is still... Figure 7 The dark signal represented by the black rectangle shown in (b) is activated simultaneously with the first time-division signal and the second time-division signal when the target row sub-pixel group (i.e., row Gi) and the neighboring row sub-pixel group are scanned synchronously based on signal Gi and signal Gi+1. Thus, the dark signal can be simultaneously filled into N*N sub-pixels (i.e., the first to fourth sub-pixels) through the same data line Sj, thereby saving the scanning time of 1 row in the first frame period.

[0090] Step A20: During the second frame period, enable data line Sj to switch the dark signal to a bright signal, and when the first time-division signal and the second time-division signal are activated, simultaneously scan the target row sub-pixel group and the neighboring row sub-pixel group to simultaneously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the bright signal.

[0091] In this embodiment, refer to Figure 4 as well as Figure 7 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 7As shown in (a) of the second frame period, enabling data line Sj switches the dark signal to a bright signal, and because the brightness data provided by data line Sj in the row where the neighboring row sub-pixel group is located (i.e., row Gi+1) is still... Figure 7 As shown in (b), when the bright signal is scanned synchronously based on signal Gi and signal Gi+1, the first time-division signal and the second time-division signal are also activated simultaneously. Thus, the bright signal can be simultaneously filled into N*N sub-sub-pixels (i.e., the first to fourth sub-sub-pixels) through the same data line Sj, thereby saving the scanning time of 1 line in the second frame period.

[0092] Step A30: During the third frame period, enable data line Sj to switch the bright signal to the dark signal, and when the first time-division signal and the second time-division signal are activated, simultaneously scan the target row sub-pixel group and the neighboring row sub-pixel group to synchronously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the dark signal.

[0093] In this embodiment, refer to Figure 4 as well as Figure 7 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 7 As shown in (a) of the third frame period, the enabled data line Sj switches the bright signal to a dark signal, and because the brightness data provided by the data line Sj in the row where the neighboring row sub-pixel group is located (i.e., row Gi+1) is still... Figure 7 The dark signal shown is activated simultaneously with the first and second time-division signals when scanning the target row sub-pixel group (i.e., row Gi) and the neighboring row sub-pixel group based on signal Gi and signal Gi+1. This allows the dark signal to be simultaneously filled into N*N sub-pixels (i.e., the first to fourth sub-pixels) through the same data line Sj, thereby saving one row of scanning time in the third frame period.

[0094] Step A40: During the fourth frame period, enable data line Sj to switch the dark signal to a bright signal, and when the first time-division signal and the second time-division signal are activated, simultaneously scan the target row sub-pixel group and the neighboring row sub-pixel group to simultaneously fill the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel with the bright signal.

[0095] In this embodiment, refer to Figure 4 as well as Figure 7 The dimming signal waveform shown in (b) is in Figure 7As shown in (a) of the fourth frame period, enabling data line Sj switches the dark signal to a bright signal, and because the brightness data provided by data line Sj in the row where the neighboring row sub-pixel group is located (i.e., row Gi+1) is still... Figure 7 The bright signal shown is activated simultaneously with the first and second time-division signals when the target row sub-pixel group (i.e., row Gi) and the neighboring row sub-pixel group are scanned synchronously based on signal Gi and signal Gi+1. This allows the bright signal to be simultaneously filled into N sub-pixels (i.e., the first to fourth sub-pixels) through the same data line Sj, thereby saving one row of scanning time in the fourth frame period.

[0096] In summary, the dual-display driver architecture of this application improves dimming accuracy while adhering to steps A10 to A40 above in the horizontal alternating illumination mode. Figure 7 Driven by the dimming signal waveform shown in (b), 4 lines of scanning time can be saved within 4 frame cycles, which is equivalent to saving half of the scanning time, thus significantly improving the dimming response speed.

[0097] Furthermore, in some other feasible embodiments, reference is made to... Figure 4 as well as Figure 8 When the sub-sub-pixel illumination mode is the single sub-sub-pixel non-illuminated mode of the third brightness level, the above step S20: according to the timing drive signal of the two control terminals of the brightness adjustment unit 10 in the sub-sub-pixel illumination mode, the data line Sj is controlled to perform time-division charging to each sub-sub-pixel in the corresponding pixel dimming unit 21, and may also include implementing steps B10 to B50.

[0098] Step B10: In the single sub-pixel unlit mode, enable the data line Sj electrically connected to the brightness adjustment unit 21 to provide a brightness signal; In this embodiment, refer to Figure 4 as well as Figure 8 ,based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 8 In (a) shown in the third brightness level L2 single sub-subpixel cyclic illumination mode, the first sub-subpixel in pixel dimming unit 21 is sequentially turned off individually within a 4-frame cycle (i.e., ... Figure 8 R1, G1, and B1 in the middle), and the second sub-pixel (i.e. Figure 8 (a) shows R2, G2, and B2), and the third sub-pixel (i.e. Figure 8 (a) shows R3, G3, and B3) and the fourth sub-pixel (i.e. Figure 8(R4, G4, and B4 are shown in (a)). Specifically, in the single sub-pixel unlit mode, the enable data line Sj continuously provides a bright signal, and intelligent collaborative control of the target row pixel group and the adjacent row sub-pixel group is achieved by precisely controlling the differentiated timing combination of the first time-division signal and the second time-division signal within a four-frame period.

[0099] Step B20: When scanning the target row sub-pixel group during the first frame period, turn off the first time-division signal and activate the second time-division signal, enabling the first sub-sub-pixel to not light up when the second sub-sub-pixel is filled with the bright signal, and activate the first time-division signal when scanning the neighboring row sub-pixel group, and synchronously fill the third sub-sub-pixel and the fourth sub-sub-pixel with the bright signal based on the activated first time-division signal and the second time-division signal.

[0100] In this embodiment, refer to Figure 4 as well as Figure 8 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) of this application specifies that the data line Sj only provides a bright signal in the single sub-pixel unlit mode. Figure 8 In the first frame period shown in (a), when Figure 8 When signal Gi, as shown in (b), is activated during the first frame period and begins scanning the row containing the target row sub-pixel group (i.e., row Gi), the first time-division signal is off while the second time-division signal is activated. The combination of the first time-division signal being off and the second time-division signal being activated ensures that the bright signal on data line Sj can only be charged into the second sub-pixel in row Gi through the second switch T2, which is turned on by the second time-division signal, to light up the second sub-pixel. At the same time, since the first switch T1 is off when the first time-division signal is off, the charging path of the first sub-pixel connected to the same data line Sj is cut off, thus successfully maintaining the dark state of the first sub-pixel, i.e., the first sub-pixel is not lit. Subsequently, when the scanning signal switches from signal Gi to signal Gi+1 to scan the row where the neighboring row sub-pixel group is located (i.e., row Gi+1), the bright signal is synchronously filled into all sub-pixels (i.e., the third sub-pixel and the fourth sub-pixel) of the neighboring row sub-pixel group through the activated first time-division signal and second time-division signal, ensuring that only the first sub-pixel is not lit during the first frame period.

[0101] Step B30: When scanning the target row sub-pixel group during the second frame period, activate the first time-division signal and turn off the second time-division signal, enabling the second sub-pixel to not light up when the first sub-pixel is filled with the bright signal, and when scanning the neighboring row sub-pixel group, synchronously fill the third sub-pixel and the fourth sub-pixel with the bright signal based on the activated first time-division signal and the second time-division signal.

[0102] In this embodiment, refer to Figure 4 as well as Figure 8 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 8 In (a) of the diagram, when the scanning signal Gi is reactivated during the second frame period and scans the row containing the target row sub-pixel group (i.e., row Gi), the first time-division signal is activated, while the second time-division signal is deactivated. Under this configuration, the bright signal continuously provided by data line Sj can only charge the first sub-sub-pixel through the first switch transistor, which is activated when the first time-division signal is active, causing the first sub-sub-pixel to change from its dark state in the first frame to its lit state. Simultaneously, since the second switch transistor T2 is deactivated when the second time-division signal is off, the charging path of the second sub-sub-pixel connected to the same data line Sj is cut off, preventing the second sub-sub-pixel from being charged and maintaining its original dark state, i.e., the second sub-sub-pixel is not lit. Subsequently, when the scanning signal switches from signal Gi to signal Gi+1 and scans to the row containing the neighboring row sub-pixel group (i.e., row Gi+1), the first time-division signal and the second time-division signal are activated simultaneously. This allows the bright signal on the data line Sj to be synchronously and parallelly charged into the third and fourth sub-pixels on row Gi+1, ensuring that the third and fourth sub-pixels remain lit during the second frame period. This ensures that only the second sub-pixel remains unlit during the second frame period.

[0103] Step B40: When scanning the target row sub-pixel group during the third frame period, activate the first time-division signal and the second time-division signal, synchronously fill the first sub-sub-pixel and the second sub-sub-pixel with the bright signal, and when scanning the neighboring row sub-pixel group, enable the third sub-sub-pixel not to light up when the fourth sub-sub-pixel is filled with the bright signal based on the activated first time-division signal and the deactivated second time-division signal.

[0104] In this embodiment, refer to Figure 4 as well as Figure 8 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 8 In the third frame period shown in (a), when the scanning signal Gi is activated again and scans the row containing the target row sub-pixel group (i.e., row Gi), the first time-division signal and the second time-division signal are activated simultaneously. Under this configuration, the brightness signal continuously provided on the data line Sj is synchronously and in parallel charged into the first sub-pixel and the second sub-pixel on row Gi, so that both the first sub-pixel and the second sub-pixel are lit up in the third frame period.

[0105] Subsequently, when the scanning signal switches from signal Gi to signal Gi+1 and scans to the row containing the neighboring row of sub-pixels (i.e., row Gi+1), the first time-division signal remains active, while the second time-division signal is turned off. At this time, the bright signal continuously provided by data line Sj can only charge the fourth sub-pixel through the first switch transistor, which is turned on when the first time-division signal is active, so that the fourth sub-pixel remains lit throughout the third frame cycle. At the same time, since the second switch transistor T2 is turned off when the second time-division signal is off, the charging path of the third sub-pixel connected to the same data line Sj is cut off, so that the third sub-pixel cannot be charged, thus keeping the third sub-pixel in a dark state, the opposite of that in the first two frames, during the third frame cycle, ensuring that only the third sub-pixel is not lit during the third frame cycle.

[0106] Step B50: When scanning the target row sub-pixel group in the fourth frame period, activate the first time-division signal and the second time-division signal, synchronously fill the first sub-sub-pixel and the second sub-sub-pixel with the bright signal, and when scanning the neighboring row sub-pixel group, enable the fourth sub-sub-pixel not to be lit when the third sub-sub-pixel is filled with the bright signal based on the closed first time-division signal and the activated second time-division signal.

[0107] In this embodiment, refer to Figure 4 as well as Figure 8 The dimming signal waveform shown in (b) is based on Figure 4 The driving architecture of the dimming unit layer shown in (b) is as follows: Figure 8 In the fourth frame period shown in (a), when the scanning signal Gi is activated again and scans the row where the target row sub-pixel group is located (i.e., row Gi), the first time-division signal and the second time-division signal continue to be activated simultaneously, so that the bright signal provided by the data line Sj can be synchronously and parallelly filled into the first sub-pixel and the second sub-pixel on row Gi again, ensuring that the first sub-pixel and the second sub-pixel are stably kept in the lit state in the fourth frame period, which is consistent with the processing method in the third frame period.

[0108] Subsequently, when the scanning signal switches from signal Gi to signal Gi+1 scanning the row containing the neighboring row of sub-pixels (i.e., row Gi+1), the second time-division signal remains active, while the first time-division signal is switched from active to off. This ensures that the bright signal continuously provided by data line Sj can only charge the third sub-pixel through the second switch, which is activated when the second time-division signal is active, thus keeping the third sub-pixel continuously lit throughout the third frame cycle. Simultaneously, since the first switch T1 is off when the first time-division signal is off, the charging path to the fourth sub-pixel connected to the same data line Sj is cut off, preventing the fourth sub-pixel from being charged. This keeps the fourth sub-pixel in a dark state, the opposite of the previous three frames, throughout the fourth frame cycle, ensuring that only the fourth sub-pixel remains unlit during the fourth frame cycle.

[0109] In summary, the dual-display driver architecture configured in this application improves dimming accuracy while, based on steps B10 to B50 above, operating in the single sub-pixel unlit mode... Figure 8 Driven by the dimming signal waveform shown in (b), each sub-pixel in the enabled pixel dimming unit 21 obtains a precise 1 / 4 duty cycle off period within four frame cycles, ultimately achieving an equivalent 3 / 4 brightness level output.

[0110] Furthermore, in some feasible embodiments, when the sub-pixel illumination mode is the sub-pixel full illumination mode of the fourth brightness level, the above step S20: according to the timing drive signal of the two control terminals of the brightness adjustment unit 10 in the sub-pixel illumination mode, controlling the data line Sj to perform time-division charging to each sub-pixel in the corresponding pixel dimming unit 21, may also include implementing steps C10 to C20.

[0111] Step C10: When the enable data line Sj provides a light signal, the first time-division signal and the second time-division signal are activated simultaneously.

[0112] In this embodiment, refer to Figure 5 as well as Figure 9 In the four-frame cycle of the sub-pixel full illumination mode of the fourth brightness level L3, an efficient fully parallel driving strategy is adopted. That is, the data line Sj is enabled to continuously provide a bright signal in the four-frame cycle, and based on the first and second time-division signals that are synchronously activated, the bright signal of the data line Sj can be synchronously filled into the target row sub-pixel group and the neighboring row sub-pixel group.

[0113] Step C20: When scanning the target row sub-pixel group in each frame period, the bright signal is filled into the first sub-pixel and the second sub-pixel based on the activated first time-division signal and the second time-division signal, and when scanning the neighboring row sub-pixel group, the bright signal is filled into the third sub-pixel and the fourth sub-pixel based on the activated first time-division signal and the second time-division signal.

[0114] In this embodiment, during each frame cycle, when scanning the row containing the target row sub-pixel group (i.e., row Gi) based on signal Gi, the first time-division signal and the second time-division signal are activated synchronously to ensure that the first sub-sub-pixel and the second sub-sub-pixel are charged in parallel. Next, when the scanning signal switches from signal Gi to signal Gi+1 to scan the row containing the neighboring row sub-pixel group (i.e., row Gi+1), the third sub-sub-pixel and the fourth sub-sub-pixel are also illuminated synchronously through the coordinated action of the activated first time-division signal and the second time-division signal. This can compress the scanning time of 2 rows (i.e., row Gi and row Gi+1) required by the traditional architecture to a single-row equivalent operation. By maximizing the utilization of the data line, the scanning efficiency is significantly improved. At the same time, it ensures that all sub-sub-pixels obtain a completely consistent charging effect. This not only perfectly adapts to the output requirements of the highest brightness level, but also significantly improves the dimming response speed by reducing the scanning operation by 50%, providing the best energy efficiency performance for high brightness scenes and significantly improving the dimming accuracy of the dual display driving architecture.

[0115] Furthermore, in some other feasible embodiments, the dimming display method provided in this application also includes the following implementation steps D10 to D30.

[0116] Step D10: Determine the light-dark transition edge region based on the display information of the input screen, and determine the sub-pixel positions that need to be compensated in the light-dark transition edge region.

[0117] In this embodiment, in response to the power-on operation of the display device, through the display device such as Figure 11 The MCU (Microcontroller Unit) shown parses the edge information in the display information of the input screen to obtain... Figure 10 The diagonal arrows indicate the light-dark transition edge region; next, determine the sub-pixel positions that need compensation within the light-dark transition edge region. For example, the sub-pixel positions that need compensation within the light-dark transition edge region could be... Figure 10 The diagonal arrows shown pass through sub-pixels R2, G4, G2, B4, B2, R4, R2, and G4 in sequence.

[0118] It should be noted that edge information can be understood as pixel-level feature data at the boundary between bright and dark areas in the input image.

[0119] Step D20: Determine the brightness values ​​of the bright and dark areas adjacent to the sub-pixel position, and use the median brightness value between the bright and dark areas as the compensation brightness display data.

[0120] In this embodiment, the MCU acquires the brightness values ​​of the bright and dark areas adjacent to the sub-pixel position, and sends the median brightness value between the bright and dark areas as compensation brightness display data. Figure 11 The Tcon (Timing Controller) shown is shown.

[0121] Step D30: When scanning to the row where the sub-pixel is located, the data line Sj is controlled to provide the compensation brightness display data to charge the sub-pixel at the sub-pixel position based on the charging timing signal mapped by the sub-pixel position.

[0122] In this embodiment, after receiving the compensated brightness display data at the sub-sub-pixel position, Tcon parses the compensated brightness display data at the sub-sub-pixel position to obtain the charging timing signal mapped to the sub-sub-pixel position (i.e., the activation timing of the timing drive signal), and sends the charging timing signal to... Figure 11 The Driver region is located in the middle. Next, when the Driver region scans to the row where the sub-pixel is located, it controls the data line Sj to provide the compensation brightness display data according to the charging timing signal to charge the sub-pixel at the sub-pixel position, thereby solving the dimming problem of the dual-unit display architecture and the problems of jagged edges and uneven transitions in the display, and optimizing the display effect of the display device.
