Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to a light-emitting panel and a display device. Background Technology

[0002] Traditional Liquid Crystal Displays (LCDs) display data based on the principle of spatial color mixing, typically incorporating color filters. However, in recent years, with the rapid development of LCD technology and evolving needs, the requirements for LCDs have increased, with low-power, high-resolution displays becoming the mainstream. Compared to traditional LCD technology, field-sequential liquid crystal display (FSL) technology, combining a color backlight and a monochrome panel, can replace the traditional color filter (CF) to achieve light mixing. This technology not only saves on CF material costs but also reduces transmittance loss due to color resist absorption of backlight, thus lowering power consumption. Therefore, it is increasingly being used in the LCD field.

[0003] However, in existing field-sequence LCD technology, insufficient refresh rate, screen switching delay, long display response time, and viewing angle issues can all cause the human eye to perceive misalignment of different colors, resulting in color separation and affecting user experience and satisfaction. Summary of the Invention

[0004] To address the aforementioned technical problems, this disclosure provides a light-emitting panel and a display device to solve the problem that color separation easily occurs in existing field-sequence liquid crystal display devices, affecting user viewing experience and satisfaction.

[0005] This disclosure provides a light-emitting panel, including multiple light-emitting units, wherein the light-emitting units include different light-emitting colors; A display stage of the luminescent panel comprises N subframes; where N = 3n, and n ≥ 2, and n is an integer; a display stage comprises n subframe groups, and the luminescent units in a subframe group switch between different luminescent colors; where... In a display phase, the switching order of the light emission colors of the light emission units in at least two subframe groups is different.

[0006] Based on the same inventive concept, this disclosure also provides a display device, which includes the above-mentioned light-emitting panel.

[0007] The technical solution provided in this disclosure has the following advantages compared with the prior art: The light-emitting panel disclosed herein includes multiple light-emitting units, each emitting a different color. A display phase of the light-emitting panel comprises N subframes, where N = 3n and n ≥ 2, and n is an integer. This means a display phase includes at least six subframes. Dividing the time of a display phase into more subframes than the conventional three subframes in existing technologies shortens the time of each subframe, preventing the light-emitting color of the current subframe from being perceived by the human eye for an excessively long period. This avoids noticeable color residue or ghosting when colors switch between adjacent subframes. The disclosure also sets a display phase to include n subframe groups. Within a subframe group, the light-emitting units emit different colors, but within a display phase, at least two subframe groups have different color switching sequences. Because the human eye responds differently to RGB colors and is more sensitive to the continuity of the same RGB color emission sequence, it is easier to perceive color residue, ghosting, and color abrupt changes. Therefore, this disclosure sets up a display stage in which the light-emitting units of at least two sub-frames switch different light-emitting colors. This can break the continuity of the same light-emitting order of the three RGB colors, and the impact of inconsistent response speeds of the three RGB colors will be distributed to different sub-frames, making color switching smoother. This can reduce ghosting and color difference, break the perceptual impact of the continuity of the same light-emitting order of the three RGB colors, improve the visual fusion effect, and optimize the color difference between some adjacent sub-frames. This reduces the difference in color information superimposed on the human eye's retina, thereby effectively suppressing color separation and improving the user's viewing experience.

Detailed Implementation

[0011] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0012] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0013] Please refer to the reference. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a planar structure of a light-emitting panel provided in an embodiment of this disclosure. Figure 2 yes Figure 1 This embodiment provides a light-emitting panel 000, which includes multiple light-emitting units 00, each of which emits a different light-emitting color. A display stage F of the luminous panel 000 includes N subframes sf; where N = 3n, and n ≥ 2, and n is an integer; a display stage F includes n subframe groups, and the luminous units 00 in a subframe group switch between different luminous colors; where... In a display phase F, the switching order of the light emission colors of the light emission units 00 in at least two subframe groups is different.

[0014] Specifically, the light-emitting panel 000 provided in this embodiment may include multiple light-emitting units 00, each of which can switch to different colors; that is, each light-emitting unit 00 includes different light-emitting colors, such as red (R), green (G), and blue (B). This embodiment... Figure 1 This embodiment illustrates an example where a light-emitting unit 00 includes at least three light-emitting devices of different colors. Lighting up different light-emitting devices switches the light emission color of the light-emitting unit 00. In practice, the light-emitting unit 00 can switch colors and may have other implementation methods, which will not be elaborated upon here. The light-emitting panel 000 in this embodiment can be used directly as a display panel, or it can be used as a backlight module. By switching the light emission color of the light-emitting unit 00, it can be used as a color backlight module. Then, in conjunction with a monochrome liquid crystal panel as pixel switches, field-sequential liquid crystal display technology can be achieved. That is, the light-emitting panel 000, as a backlight module, uses RGB three-color backlights to light up sequentially. Combined with the pixel switches of the liquid crystal panel, color mixing is achieved in time. Utilizing the persistence of vision effect (i.e., the image seen by the eye is briefly retained on the retina), the color display effect observed by the human eye is achieved.

[0015] like Figure 3 As shown, Figure 3 It is Figure 1The provided schematic diagram illustrates the principle architecture of using the light-emitting panel as a backlight module to achieve color display. The overall structure of the field-sequence display technology can include a light-emitting panel 000, a liquid crystal panel 111, a data control generator 333, a timing control unit 444, and a backlight controller 555. External image signals are input to the data control generator 333, which performs preprocessing such as format conversion and encoding on the signals to provide basic data for subsequent driving and backlight control. For example, after the image signal is input, the data control generator 333 decomposes the image information into red, green, and blue (RGB) grayscale data components, which are then transmitted to the backlight controller 555. This controls the light-emitting panel 000 of the backlight module to emit red, green, and blue (RGB) light sequentially in time. After the image signal is input, it is decomposed into timing signals by the data control generator 333 and output to the timing control unit 444. The timing control unit 444 generates precise timing signals to control the data driver circuit 111A and the gate driver circuit 111B of the liquid crystal panel 111 respectively. The gate driver circuit 111B selects the liquid crystal pixel rows one by one, and the data driver circuit 111A applies the corresponding data voltage to the selected pixel rows to control the light transmittance of the liquid crystal pixels. Finally, with the help of the persistence of vision of the human eye, the RGB three colors of light and the light transmittance control of the liquid crystal pixels are switched synchronously and quickly. The human eye perceives these three colors mixed together and finally forms a color image. LCD devices employing field-sequential display technology utilize time-sequential color separation and visual persistence. The light-emitting panel 000 acts as a backlight module, controlling the RGB backlight to emit light in a time-sequential manner. This is combined with the monochrome LCD panel 111, which acts as a pixel switch to rapidly switch data signals within a specific cycle. By leveraging the visual persistence effect of the human eye, the three light sources can be directly mixed in time, eliminating the need for color filters in traditional LCD displays. By using the backlight to sequentially switch the RGB three colors and coordinating with the synchronized light control of the LCD pixels, a color display effect is achieved, resulting in higher brightness and color gamut.

[0016] like Figure 4 As shown, Figure 4 yes Figure 3 The diagram shown illustrates a switching sequence of emission colors used in the relevant technologies when the light-emitting panel is used as a backlight module. Figure 4 The relevant technologies used in this paper employ a light-emitting panel where the color switching sequence of the light-emitting units is the same at different times, all being RGB. That is, assuming a display phase F includes... Figure 4If the multiple subframes shown represent a time period sf, the color sequence of the light-emitting unit in the continuous multiple display stages F is RGBRGBRGB... a single color repeated switching. Because the human eye responds to the three colors RGB at different speeds, and is more sensitive to consecutive frames of the same color switching RGB, at lower frame rates, such as when the frequency of color switching of the light-emitting panel is not high enough, or the liquid crystal deflection in the LCD panel cannot keep up with the switching frequency of the light-emitting panel, or when the brightness difference of RGB colors is relatively obvious, the human eye will capture individual colors due to the persistence of vision, and will be more likely to perceive color jumps and different color misalignments. That is, subframes of different colors may stay at different positions on the retina, and the human eye is more likely to perceive color residue, ghosting, or color abrupt changes, resulting in color separation.

[0017] To address the aforementioned issues, this embodiment sets one display stage F of the light-emitting panel 000 to include N subframes sf; where N = 3n, and n ≥ 2, where n is an integer. This means that one display stage F includes at least 6 or more subframes sf, or at least a multiple of 3n, where n is an integer greater than or equal to 2. One display stage F can be understood as one frame time, referring to the time required for the display device to complete one frame image refresh (or presentation), typically measured in seconds. This embodiment breaks down the time of one display stage F into a larger number of subframes sf than the conventional 3 subframes sf in the prior art. This shortens the time of each subframe, preventing the light-emitting unit 00's current subframe color from being stored for an excessively long time in human perception, thus avoiding noticeable color residue or ghosting when adjacent subframe colors switch.

[0018] This embodiment also sets a display stage F to include n subframe groups. Since a display stage F includes N subframes sf, where N=3n and n≥2, if a display stage F includes 6 subframes sf, then a display stage F can be divided into 2 subframe groups; if a display stage F includes 9 subframes sf, then a display stage F can be divided into 3 subframe groups; if a display stage F includes 12 subframes sf, then a display stage F can be divided into 4 subframe groups. This embodiment does not limit this; in specific implementation, the setting can be selected according to actual needs. Figure 2 The example provided is based on the case where a display phase F consists of 6 subframes sf, and a display phase F can be divided into 2 subframe groups.

[0019] Understandable, Figure 2The first row of the timing sequence indicates the timing when the light-emitting unit with a red emission color (R) is illuminated during the two display stages (F). The second row indicates the timing when the light-emitting unit with a green emission color (G) is illuminated during the two display stages (F). The third row indicates the timing when the light-emitting unit with a blue emission color (B) is illuminated during the two display stages (F). In practice, the colors of the three rows of timing sequences can be interchanged. For example, the first row could indicate the timing when the light-emitting unit with a green emission color (G) is illuminated during the two display stages (F), the second row could indicate the timing when the light-emitting unit with a blue emission color (B) is illuminated during the two display stages (F), and the third row could indicate the timing when the light-emitting unit with a red emission color (R) is illuminated during the two display stages (F), and so on. This embodiment... Figure 2 This is just an example; in actual implementation, you can choose flexibly and make reasonable settings.

[0020] In this embodiment, different light-emitting units 00 in a subframe group switch light emission colors, such as... Figure 2 As shown, a display stage F includes two sub-frame groups, and each sub-frame group has three different light emission colors (RGB) that switch to emit light. That is, the light emission unit 00 switches between three different light emission colors (R, G, and B) in the three sub-frames sf of the same sub-frame group.

[0021] However, in a display stage F, the switching order of the light emission colors of the light emission units 00 in at least two subframe groups is different. For example, in a display stage F that includes two subframe groups, if the switching order of the light emission colors of the three subframes sf in the first subframe group f1 is RGB, then the switching order of the light emission colors of the three subframes sf in the second subframe group f2 is definitely not RGB. The switching order of the light emission colors of the three subframes sf in the second subframe group f2 can be RGB (e.g., ...). Figure 2 (as shown), or the switching order of the emission colors of the three subframes sf in the second subframe group f2 can be GBR (as shown). Figure 5 As shown, Figure 5 yes Figure 1 (Another diagram showing the switching order of the luminous panel's luminous colors in the two display stages), or the switching order of the luminous colors of the three subframes sf in the second subframe group f2 is GRB (e.g.) Figure 6 As shown, Figure 6 yes Figure 1 (Another diagram showing the switching order of the light-emitting panel's light-emitting colors in the two display stages), or the switching order of the light-emitting colors of the three subframes sf in the second subframe group f2 is BRG (e.g., Figure 7 As shown, Figure 7 yes Figure 1(Another diagram showing the switching order of the luminous panel's luminous colors in the two display stages), or the switching order of the luminous colors of the three subframes sf in the second subframe group f2 is BGR (e.g.) Figure 8 As shown, Figure 8 yes Figure 1 (A schematic diagram illustrating another switching sequence of the luminous panel's luminous colors in the two display stages).

[0022] Because the human eye responds differently to RGB colors and is more sensitive to the continuity of the same light emission sequence of RGB colors, it is easier to perceive color retention, ghosting, and color abrupt changes. Therefore, this embodiment sets the switching order of the light emission colors of the light emission units 00 in at least two sub-frame groups in a display stage F to be different. This breaks the continuity of the same light emission sequence of RGB colors, and the impact of inconsistent response speeds of RGB colors is distributed across different sub-frames sf, resulting in smoother color switching. This reduces ghosting and color difference, breaks the perceptual impact of the continuity of the same light emission sequence of RGB colors, and helps improve the visual fusion effect. Figure 9 As shown, Figure 9 The light-emitting panel of this embodiment adopts Figure 5 A schematic diagram illustrating the principle of the switching order of the light emission colors of the light-emitting units in the middle, and setting a display stage F in which the switching order of the light emission colors of the light-emitting units 00 in at least two sub-frame groups is different. Figure 9 A display phase F includes two subframe groups: the first subframe f11, the second subframe f12, the third subframe f13 (the first subframe group), and the fourth subframe f21, the fifth subframe f22, and the sixth subframe f23 (the second subframe group). This can optimize the color differences between some adjacent subframes sf, reduce the differences in color information superimposed on the human retina, and thus effectively suppress color separation, improving the user's viewing experience.

[0023] It should be noted that in this embodiment... Figure 1 The diagram only illustrates the structure of the light-emitting panel 000. In specific implementations, the structure of the light-emitting panel 000 and the arrangement of the light-emitting units 00 may include, but are not limited to, this. Other configuration structures are also possible. For details, please refer to the structure of the light-emitting panel in related technologies. This embodiment will not elaborate further. The focus of this embodiment and subsequent embodiments is to illustrate that in a display stage F of the light-emitting panel 000, the switching order of the light-emitting colors of the light-emitting units 00 in at least two sub-frame groups is different.

[0024] In some alternative embodiments, please continue to refer to the references. Figure 1 , Figure 2 , Figures 5-8In this embodiment, for the same light-emitting unit 00, the light emission color of the two adjacent subframes sf in two adjacent subframe groups in a display stage F is different from the light emission color of the two adjacent subframes sf in two adjacent display stages F.

[0025] This embodiment explains that for the same light-emitting unit 00, in a display stage F, the switching order of the light-emitting colors of at least two subframe groups of light-emitting units 00 is different. Specifically, the light-emitting colors of two adjacent subframes sf in two adjacent subframe groups within a display stage F may differ from the light-emitting colors of two adjacent subframes sf in two adjacent display stages F. like Figure 2 As shown, in a display stage F, the light emission colors of two adjacent subframes sf in two adjacent subframe groups are blue (B) and red (R), and the light emission colors of two adjacent subframes sf in two adjacent display stages F are green (G) and red (R). Therefore, the light emission colors of two adjacent subframes sf in two adjacent subframe groups in a display stage F (blue (B) and red (R)) are different from the light emission colors of two adjacent subframes sf in two adjacent display stages F (green (G) and red (R)).

[0026] like Figure 5 As shown, in a display stage F, the light emission colors of two adjacent subframes sf in two adjacent subframe groups are blue (B) and green (G), and the light emission colors of two adjacent subframes sf in two adjacent display stages F are red (R) and red (R). Therefore, the light emission colors of two adjacent subframes sf in two adjacent subframe groups in a display stage F (blue (B) and green (G)) are different from the light emission colors of two adjacent subframes sf in two adjacent display stages F (red (R) and red (R)).

[0027] like Figure 6 As shown, in a display stage F, the light emission colors of two adjacent subframes sf in two adjacent subframe groups are blue (B) and green (G), and the light emission colors of two adjacent subframes sf in two adjacent display stages F are blue (B) and red (R). Therefore, the light emission colors (blue (B) and green (G)) of two adjacent subframes sf in two adjacent subframe groups in a display stage F are different from the light emission colors (blue (B) and red (R)) of two adjacent subframes sf in two adjacent display stages F.

[0028] like Figure 7 As shown, in a display stage F, the emission colors of two adjacent subframes sf in two adjacent subframe groups are blue B and blue B, respectively. The emission colors of two adjacent subframes sf in two adjacent display stages F are green G and red R, respectively. Therefore, the emission colors of two adjacent subframes sf in two adjacent subframe groups in a display stage F (blue B and blue B) are different from the emission colors of two adjacent subframes sf in two adjacent display stages F (green G and red R).

[0029] like Figure 8 As shown, in a display stage F, the emission colors of two adjacent subframes sf in two adjacent subframe groups are blue B and blue B, respectively, and the emission colors of two adjacent subframes sf in two adjacent display stages F are red R and red R, respectively. Therefore, the emission colors of two adjacent subframes sf in two adjacent subframe groups in a display stage F (blue B and blue B) are different from the emission colors of two adjacent subframes sf in two adjacent display stages F (red R and red R).

[0030] In this embodiment, for the same light-emitting unit 00, the light-emitting colors of two adjacent subframes sf in two adjacent subframe groups within a display stage F are different from the light-emitting colors of two adjacent subframes sf in two adjacent display stages F. This not only allows the switching order of the light-emitting colors of light-emitting units 00 in at least two adjacent subframe groups within a display stage F to be different, breaking the continuity of the same RGB light-emitting order in a single display stage F, resulting in smoother color switching and improved visual fusion effect, but also allows the light-emitting unit 00 to break the continuity of the same RGB light-emitting order when switching between two adjacent display stages F, which is beneficial to improving the visual fusion effect.

[0031] Optional, please refer to the following: Figure 1 , Figure 2 , Figures 5-8 In this embodiment, for the same light-emitting unit 00, the light-emitting colors of two adjacent subframes sf in two adjacent subframe groups within a display stage F are defined as the first color group, and the light-emitting colors of two adjacent subframes sf in two adjacent display stages F are defined as the second color group. Therefore, the light-emitting colors of two adjacent subframes sf in two adjacent subframe groups within a display stage F are different from the light-emitting colors of two adjacent subframes sf in two adjacent display stages F. This can be understood as two colors in the first color group being the same, and two colors in the second color group being the same. Figure 8 As shown, the two colors in the first color group are the same, such as both being blue (B); the two colors in the second color group are the same, such as both being red (R); and the two blue (B) and two red (R) colors are all different. Alternatively, it can be understood that one color in the first color group is different from one color in the second color group, such as... Figure 2 As shown, the two colors in the first color group are different, such as blue (B) and red (R). The two colors in the second color group are also different, such as green (G) and red (R). The blue (B) in the first color group is different from the green (G) in the second color group. Figure 6As shown, the two colors in the first color group are different, such as blue (B) and green (G). The two colors in the second color group are also different, such as blue (B) and red (R). The green (G) in the first color group is different from the red (R) in the second color group. Alternatively, it can be understood that both colors in the first color group are different from both colors in the second color group. Figure 5 As shown, the two colors in the first color group are different, such as blue (B) and green (G). The two colors in the second color group are the same, such as red (R). The blue (B) and green (G) in the first color group are different from the two red (R) colors in the second color group. Figure 7 As shown, the two colors in the first color group are the same, such as both being blue (B). The two colors in the second color group are different, such as green (G) and red (R). The two blues (B) in the first color group are different from the green (G) and red (R) in the second color group. This disrupts the repetitive pattern of the emission color continuity between adjacent subframe groups, providing a wider range of visual tones, which helps improve color fusion and color separation.

[0032] It should be noted that in this embodiment... Figure 2 , Figures 5-8 This is merely an example illustrating the switching order of the emission colors of the 6 subframes sf in a display stage F when it is divided into 2 subframe groups. It does not mean that in actual implementation, only the above 5 switching orders are included. Any switching order that satisfies the different switching orders of the emission colors of the emission units 00 in at least two subframe groups in a display stage F is within the protection scope of this embodiment.

[0033] It is understood that the above embodiments Figure 2 , Figures 5-9 The example provided uses a display phase F consisting of 6 subframes (sf) and can be divided into 2 subframe groups. In practice, optionally, a display phase F can consist of 9 subframes (sf) and can be divided into 3 subframe groups, as shown below. Figure 10 and Figure 11 As shown, Figure 10 yes Figure 1 This diagram illustrates an alternative sequence of color switching for the luminescent panel in the two display stages. Figure 11 yes Figure 1The diagram illustrates another switching sequence of the light-emitting panel's light-emitting colors in two display stages. In one subframe group, the light-emitting unit 00 switches to different light-emitting colors. In one display stage F, which includes three subframe groups, each subframe group has three different light-emitting colors (RGB) that switch to light-emitting colors. That is, the light-emitting unit 00 switches to three different light-emitting colors (R, G, and B) in the three subframes sf of the same subframe group. However, in a display stage F, the switching order of the light emission colors of the light emission units 00 in at least two subframe groups is different. For example, in a display stage F comprising three subframe groups, if the switching order of the light emission colors of the three subframes sf in the first subframe group f1 is RGB, then the switching order of the light emission colors of the three subframes sf in the second subframe group f2 and the third subframe group f3 are not RGB. However, the switching order of the light emission colors of the three subframes sf in the second subframe group f2 is the same as that in the third subframe group f3, and neither is RGB, such as both being GBR (e.g., ...). Figure 10 (As shown); or if the light emission color switching order of the three subframes sf in the first subframe group f1 is RGB, then the light emission color switching order of the three subframes sf in the second subframe group f2 and the three subframes sf in the third subframe group f3 are not RGB, and the light emission color switching order of the three subframes sf in the second subframe group f2 is also different from that of the three subframes sf in the second subframe group f2. For example, the light emission color switching order of the three subframes sf in the second subframe group f2 is GBR, and the light emission color switching order of the three subframes sf in the third subframe group f3 is BRG (e.g.) Figure 11 As shown), a display stage F includes 9 subframes sf. When the 9 subframes sf are divided into 3 subframe groups, the switching order of the light emission colors of the light emission units 00 in at least two subframe groups in a display stage F is different.

[0034] And as Figure 10 and Figure 11 As shown, it also satisfies that for the same light-emitting unit 00, the light emission color of two adjacent subframes sf in two adjacent subframe groups in a display stage F is different from the light emission color of two adjacent subframes sf in two adjacent display stages F. This embodiment will not be elaborated here; please refer to the relevant documentation for details. Figure 10 and Figure 11 To understand.

[0035] In some optional embodiments, a display stage F of the light-emitting panel 000 in this embodiment includes N subframes sf; where N=3n, and n can be an integer greater than or equal to 3, that is, n≥3 and n is an integer; a display stage F includes at least 3 subframe groups, and the light-emitting units 00 in a subframe group switch light emission with different emission colors. For the same light-emitting unit 00, in the at least three subframe groups included in a display stage F, the switching order of the emission colors of the light-emitting units 00 in at least two subframe groups is different. This embodiment divides the time of a display stage F into at least 9 subframes sf, which can shorten the time of each subframe sf in the same frame time, which is beneficial to better avoid the light emission color of the current subframe of the light-emitting unit 00 causing too long a temporary storage in human eye perception, thereby avoiding obvious color residue or ghosting perceived by the human eye when the colors of adjacent subframes switch.

[0036] In some alternative embodiments, please refer to the references. Figure 1 , Figures 12-14 , Figure 12 yes Figure 1 A schematic diagram illustrating the switching sequence of the light-emitting panel's light-emitting colors during a display phase. Figure 13 yes Figure 1 A schematic diagram illustrating another switching sequence of the light-emitting panel's light-emitting colors during a display phase. Figure 14 yes Figure 1 The diagram illustrates another switching sequence of the luminous color of the luminous panel in a display stage. In this embodiment, when n≥3, that is, when a display stage F of the luminous panel 000 includes at least 9 subframes sf, and the at least 9 subframes sf of a display stage F includes at least 3 subframe groups, the luminous color of the two adjacent subframes sf of two adjacent subframe groups in a display stage F is different from the luminous color of the two adjacent subframes sf of another two adjacent subframe groups in the same display stage F.

[0037] This embodiment explains that for the same light-emitting unit 00, in a display stage F, assuming it includes 9 subframes sf, and these 9 subframes sf are divided into 3 subframe groups, then the switching order of the light-emitting colors of the light-emitting units 00 in at least two subframe groups is different. This can be understood as the light-emitting colors of two adjacent subframes sf in two adjacent subframe groups within a display stage F being different from the light-emitting colors of two adjacent subframes sf in another two adjacent subframe groups within the same display stage F. Specifically… like Figure 12As shown, in a display stage F, the light emission colors of two adjacent subframes sf in two adjacent subframe groups are blue B and blue B, respectively. In the same display stage F, the light emission colors of two adjacent subframes sf in another two adjacent subframe groups are green G and green G, respectively. Therefore, the light emission colors of two adjacent subframes sf in two adjacent subframe groups in a display stage F (blue B and blue B) are different from the light emission colors of two adjacent subframes sf in another two adjacent subframe groups in the same display stage F (green G and green G). like Figure 13 and Figure 14 As shown, in a display stage F, the light emission colors of two adjacent subframes sf in two adjacent subframe groups are blue (B) and green (G), respectively. In another display stage F, the light emission colors of two adjacent subframes sf in two other adjacent subframe groups are blue (B) and blue (B). Therefore, the light emission colors of two adjacent subframes sf in two adjacent subframe groups in a display stage F (blue (B) and green (G)) are different from the light emission colors of two adjacent subframes sf in another display stage F (blue (B) and blue (B)). In this embodiment, for the same light-emitting unit 00, the light-emitting colors of two adjacent subframes sf in two adjacent subframe groups within a display stage F are different from the light-emitting colors of two adjacent subframes sf in another two adjacent subframe groups within the same display stage F. This allows the switching order of the light-emitting colors of the light-emitting units 00 in two adjacent subframe groups within a display stage F to be different, breaking the continuity of the same RGB light-emitting order in a single display stage F, disrupting the repetitive pattern of the continuous light-emitting colors between adjacent subframe groups, and improving the visual fusion effect.

[0038] Optional, please refer to the following: Figure 1 , Figures 10-14 In this embodiment, for the same light-emitting unit 00, in a display stage F, the light-emitting color of the two adjacent subframes sf of the m-th subframe group and the (m+1)-th subframe group is the third color group, and the light-emitting color of the two adjacent subframes sf of the (m+1)-th and (m+2)-th subframe groups is the fourth color group, where m is a positive integer. Therefore, the light-emitting color of the two adjacent subframes sf of two adjacent subframe groups in a display stage F is different from the light-emitting color of the two adjacent subframes sf of other two adjacent subframe groups in the same display stage F. This can be understood as the third color group and the fourth color group being different. Specifically, It can be that two colors in the third color group are different, two colors in the fourth color group are different, and at least one color in the third color group is different from at least one color in the fourth color group. For example... Figure 10As shown, in a display phase F, the emission colors of two adjacent subframes sf in two adjacent subframe groups are the third color group, which consists of blue (B) and green (G). The two colors in the third color group are different. In the same display phase F, the emission colors of two adjacent subframes sf in another two adjacent subframe groups are the fourth color group, which consists of red (R) and green (G). The two colors in the fourth color group are different, but at least one color in the third color group (blue (B)) and at least one color in the fourth color group (red (R)) are different. Figure 11 As shown, in a display stage F, the emission colors of two adjacent subframes sf in two adjacent subframe groups are the third color group, which consists of blue (B) and green (G). The two colors in the third color group are different. In the same display stage F, the emission colors of two adjacent subframes sf in two other adjacent subframe groups are the fourth color group, which consists of red (R) and blue (B). The two colors in the fourth color group are different, but at least one color in the third color group (green (G)) and at least one color in the fourth color group (red (R)) are different.

[0039] It can also mean that two colors in the third color group are the same, two colors in the fourth color group are the same, and at least one color in the third color group is different from at least one color in the fourth color group; for example... Figure 12 As shown, in a display stage F, the emission colors of two adjacent subframes sf in two adjacent subframe groups are the third color group, which consists of blue B and blue B. The two colors in the third color group are the same. In the same display stage F, the emission colors of two adjacent subframes sf in two other adjacent subframe groups are the fourth color group, which consists of green G and green G. The two colors in the fourth color group are the same, but at least one color in the third color group (blue B) and at least one color in the fourth color group (green G) are different.

[0040] It could also mean that the two colors in the third color group are different, the two colors in the fourth color group are the same, and at least one color in the third color group is different from at least one color in the fourth color group; for example... Figure 13 and Figure 14 As shown, in a display stage F, the emission colors of two adjacent subframes sf in two adjacent subframe groups are the third color group, which consists of blue (B) and green (G). The two colors in the third color group are different. In the same display stage F, the emission colors of two adjacent subframes sf in two other adjacent subframe groups are the fourth color group, which consists of blue (B) and blue (B). The two colors in the fourth color group are the same, but at least one color in the third color group (green (G)) and at least one color in the fourth color group (blue (B)) are different.

[0041] Alternatively, the two colors in the third color group can be the same, the two colors in the fourth color group can be different, and at least one color in the third color group and at least one color in the fourth color group can be different (not illustrated in the diagram).

[0042] In this embodiment, for the same light-emitting unit 00, the light-emitting colors of the two adjacent subframes sf in two adjacent subframe groups in a display stage F are designated as the third color group, and the light-emitting colors of the two adjacent subframes sf in another two adjacent subframe groups in the same display stage F are designated as the fourth color group. At least one color in the third color group is different from at least one color in the fourth color group. This allows the third color group and the fourth color group to be different, so that the switching order of the light-emitting colors of the light-emitting units 00 in two adjacent subframe groups in a display stage F is different. This breaks the continuity of the same RGB light-emitting order in the existing single display stage F, disrupts the repetitive pattern of the continuous light-emitting colors between adjacent subframe groups, and improves the visual fusion effect.

[0043] It should be noted that in this embodiment... Figures 10-14 This is merely an example illustrating the switching order of the emission colors of the nine subframes sf of a display stage F when it is divided into three subframe groups. It does not imply that in actual implementation, only the above five switching orders are included. Any switching order that satisfies the requirement that the emission colors of the emission units 00 in at least two subframe groups of a display stage F are different is within the protection scope of this embodiment.

[0044] In some alternative embodiments, please continue to refer to the references. Figure 1 , Figures 10-14 In this embodiment, a display stage F is configured to include at least three subframe groups, and the switching order of the light emission colors in the three subframe groups is different. That is, assuming that a display stage F includes 9 subframes sf, and the 9 subframes sf are divided into three subframe groups, the switching order of the light emission colors in the three subframe groups is different.

[0045] Optional, such as Figures 12-14 As shown, for a light-emitting unit 00, when a display stage F includes three subframe groups, the light-emitting colors of the two adjacent subframes sf between at least two adjacent subframe groups in a display stage F are the same.

[0046] like Figure 12As shown, a display stage F includes three subframe groups. Within any two adjacent subframe groups of display stage F, the adjacent subframes sf of each group emit the same color. For example, the adjacent subframes sf of the first subframe group f1 and the second subframe group f2 emit blue (B), and the adjacent subframes sf of the second subframe group f2 and the third subframe group f3 emit green (G). This ensures that the adjacent subframes sf of the first subframe group f1 and the second subframe group f2 are continuously lit with the same color, meaning there is a continuous transition between the first subframe group f1 and the second subframe group f2. When the light-emitting unit 00's blue light-emitting device is lit twice consecutively, there is no interval between the lighting of other color light-emitting devices. This allows two adjacent subframes between the second subframe group f2 and the third subframe group f3 to be lit consecutively with the same color. That is, when the second subframe group f2 and the third subframe group f3 are connected, the green light-emitting device of the light-emitting unit 00 is lit twice consecutively, with no interval between the lighting of other color light-emitting devices. This avoids the power loss caused by switching between different color light-emitting devices of the light-emitting unit 00, which helps to reduce the energy consumption of driving the light-emitting unit 00.

[0047] like Figure 13 and Figure 14 As shown, a display stage F includes three subframe groups. In the three subframe groups of a display stage F, the two adjacent subframes between the first subframe group f1 and the second subframe group f2 have different light emission colors, while the two adjacent subframes between the second subframe group f2 and the third subframe group f3 have the same light emission color. For example, the two adjacent subframes between the second subframe group f2 and the third subframe group f3 both emit blue (B). This allows the two adjacent subframes between the second subframe group f2 and the third subframe group f3 to be continuously lit with the same color. That is, when the second subframe group f2 and the third subframe group f3 are connected, the blue light-emitting device of the light-emitting unit 00 is lit twice consecutively, without any interval between the lighting of other color light-emitting devices. This avoids the power loss caused by switching different color light-emitting devices in the light-emitting unit 00, which helps to reduce the energy consumption of driving the light-emitting unit 00.

[0048] Optional, such as Figure 10 and Figure 11 As shown, for a light-emitting unit 00, when a display stage F includes three subframe groups, the light-emitting colors of the two adjacent subframes sf between any two adjacent subframe groups in a display stage F are different.

[0049] like Figure 10As shown, a display stage F includes three subframe groups. In the three subframe groups of a display stage F, the light emission colors of the two adjacent subframes sf between any two adjacent subframe groups are different. For example, the light emission colors of the two adjacent subframes between the first subframe group f1 and the second subframe group f2 are different, namely blue (B) and green (G). The light emission colors of the two adjacent subframes between the second subframe group f2 and the third subframe group f3 are also different, namely red (R) and green (G).

[0050] like Figure 11 As shown, a display stage F includes three subframe groups. In the three subframe groups of a display stage F, the light emission colors of the two adjacent subframes sf between any two adjacent subframe groups are different. For example, the light emission colors of the two adjacent subframes between the first subframe group f1 and the second subframe group f2 are different, namely blue (B) and green (G). The light emission colors of the two adjacent subframes between the second subframe group f2 and the third subframe group f3 are also different, namely red (R) and blue (B).

[0051] This embodiment enables the emission colors of two adjacent subframes sf in any two adjacent subframe groups within a display stage F to be different. This allows the switching order of the emission colors of the emission units 00 in any two adjacent subframe groups to be different within a display stage F. For the three different colored emission devices of an emission unit 00, between any two times the same color emission device is lit, there is an interval including the lighting of other colored emission devices. This effectively breaks the continuity of the same RGB emission sequence in the existing single display stage F, disrupts the repetitive pattern of emission color continuity between adjacent subframe groups, and improves the visual fusion effect.

[0052] In some alternative embodiments, please refer to the references. Figure 1 and Figure 15 , Figure 15 yes Figure 1 The diagram illustrates another switching order of the light-emitting panel's light-emitting color in a display stage. In this embodiment, for a light-emitting unit 00, a display stage F includes at least three sub-frame groups, and a display stage F includes two sub-frame groups with the same light-emitting color switching order.

[0053] This embodiment explains how a display stage F includes at least three subframe groups, such as Figure 15 As shown, taking a display stage F comprising three subframe groups as an example, for a light-emitting unit 00, a display stage F can include at least two subframe groups with the same light-emitting color switching order, such as... Figure 15As shown, the light emission color switching order of the first subframe group f1 is different from that of the second subframe group f2, and the light emission color switching order of the first subframe group f1 is different from that of the third subframe group f3, but the light emission color switching order of the second subframe group f2 is the same as that of the third subframe group f3.

[0054] Optional, such as Figure 1 , Figure 15 and Figure 16 As shown, Figure 16 yes Figure 1 The diagram illustrates another switching sequence of the emitted colors of the emitting panel during a display phase. Two subframe groups with the same emitted color switching sequence can be adjacent subframe groups (e.g., ...). Figure 15 As shown), or in some other alternative embodiments, two subframe groups with the same emission color switching order can also be two non-adjacent subframe groups (e.g. Figure 16 As shown), the light emission color switching order of the first subframe group f1 is different from that of the second subframe group f2, and the light emission color switching order of the second subframe group f2 is different from that of the third subframe group f3, but the light emission color switching order of the first subframe group f1 is the same as that of the third subframe group f3.

[0055] Optionally, when a display stage F includes more than three subframe groups, such as five subframe groups, a display stage F may include two subframe groups with the same light emission color switching order, and these subframe groups with the same light emission color switching order can be arranged alternately. Figure 1 and Figure 17 As shown, Figure 17 yes Figure 1 The diagram illustrates another switching order of the light-emitting panel's light-emitting colors in a display stage. Taking a display stage F comprising five sub-frame groups as an example, the switching order of the light-emitting colors in the first sub-frame group f1 is different from that in the second sub-frame group f2. The switching order of the light-emitting colors in the second sub-frame group f2 is different from that in the third sub-frame group f3. The switching order of the light-emitting colors in the third sub-frame group f3 is different from that in the fourth sub-frame group f4. The switching order of the light-emitting colors in the fourth sub-frame group f4 is different from that in the fifth sub-frame group f5. However, the switching order of the light-emitting colors in the first sub-frame group f1 is the same as that in the fourth sub-frame group f4, and the switching order of the light-emitting colors in the third sub-frame group f3 is the same as that in the fifth sub-frame group f5.

[0056] In this embodiment, when a display stage F includes at least three subframe groups, and the display stage F includes two subframe groups with the same light emission color switching order, it can effectively break the continuity of the same RGB light emission order in the existing single display stage F, disrupt the repetitive pattern of the light emission color continuity between adjacent subframe groups, improve the visual fusion effect, and also enable a display stage F to include two subframe groups with the same light emission color switching order, which is beneficial to reduce the computational load of the driving circuit that drives the light emission unit to emit light, and is beneficial to reduce the energy consumption of the light emission unit 00.

[0057] In some optional embodiments, it can also be configured that when the emission colors of two adjacent subframes sf are the same, the emission unit 00 remains in an emission state during the switching instant of the two subframes sf. That is, when the emission colors of two consecutive subframes sf are the same, the emission devices of the same color in the emission unit 00 are continuously lit. At this time, the emission unit 00 directly remains in an emission state, instead of turning off the emission device of that color and then turning it on again. Figure 1 and Figure 12 As shown, the light emission color of the two adjacent subframes sf between the first subframe group f1 and the second subframe group f2 is blue (B). Therefore, at the instant of switching between the two adjacent subframes sf between the first subframe group f1 and the second subframe group f2, the blue light-emitting device in the light-emitting unit 00 remains in the emitting state, and it is not necessary to turn off the blue light-emitting device and then turn it on again. Similarly, ... Figure 1 and Figure 12 As shown, the light emission color of the two adjacent subframes sf between the second subframe group f2 and the third subframe group f3 is green G. Therefore, at the moment of switching between the two adjacent subframes sf between the second subframe group f2 and the third subframe group f3, the green light-emitting device in the light-emitting unit 00 remains in the light-emitting state. It is not necessary to turn off the green light-emitting device and then turn it on again. This can reduce the frequency of switching the light-emitting device on in the light-emitting unit 00, which is beneficial to saving panel power consumption.

[0058] like Figure 1 and Figure 13As shown, the light emission colors of the two adjacent subframes sf between the first subframe group f1 and the second subframe group f2 are blue (B) and green (G), respectively. Therefore, at the instant of switching between these two adjacent subframes sf, the blue light-emitting device in the light-emitting unit 00 is turned off, meaning the blue light-emitting device needs to be turned off before the green light-emitting device is turned on. However, the light emission color of the two adjacent subframes sf between the second subframe group f2 and the third subframe group f3 is both blue (B). Therefore, at the instant of switching between these two adjacent subframes sf, the blue light-emitting device in the light-emitting unit 00 remains illuminated, without needing to be turned off and then on again. This reduces the frequency of switching the light-emitting device on and off in the light-emitting unit 00, which helps save panel power consumption.

[0059] In some alternative embodiments, please refer to the references. Figure 1 and Figure 5 , Figure 6 , Figure 8 In this embodiment, in a display stage F, the time interval between two consecutive switchings of the light-emitting unit 00 to green is Δt1, and the time interval between two consecutive switchings of the light-emitting unit 00 to red is Δt2; wherein, Δt2 > Δt1.

[0060] This embodiment explains that since the human eye is most sensitive to green, for a light-emitting unit 00, the time interval between two adjacent green light-emitting devices being lit during a timing switching cycle of one display stage F, i.e., the time interval Δt1 between two adjacent switchings of the light-emitting unit 00 to green, needs to be set to a short value. This is to avoid the human eye being sensitive to the green light-emitting interval being too long, which would cause the human eye to perceive green color separation. Therefore, it can effectively reduce the phenomenon of green color separation perceived by the human eye and ensure visual effect.

[0061] Optionally, in some other embodiments, a display stage F may be set such that the time interval between two consecutive switching of the light-emitting unit 00 to blue is Δt3; wherein Δt3 > Δt2 > Δt1.

[0062] This embodiment explains that since the human eye is most sensitive to green and least sensitive to blue, meaning the human eye responds differently to red, green, and blue, and the human eye's response speed to green is greater than its response speed to red, and its response speed to red is greater than its response speed to blue, in a display stage F, the time interval Δt3 between two consecutive switches of the light-emitting unit 00 to blue can be set to the maximum compared to the time interval between two consecutive switches to other colors. That is, in the timing switching cycle of a display stage F, the time interval between two consecutive lights of the blue light-emitting device is greater than the time interval between two consecutive lights of the red light-emitting device, and the time interval between two consecutive lights of the red light-emitting device is greater than the time interval between two consecutive lights of the green light-emitting device. Therefore, by differentiating the lighting time of different color light-emitting devices, the phenomenon of color separation perceived by the human eye can be reduced, ensuring visual effect.

[0063] In some optional embodiments, in a display stage F, the subframe duration for which the light-emitting unit 00 illuminates the red light-emitting device is longer than the subframe duration for which the light-emitting unit 00 illuminates other colored light-emitting devices, i.e., the subframe durations for different colors are differentiated. For example, in a display stage F, the subframe duration for which the light-emitting unit 00 illuminates the red light-emitting device is tr, the subframe duration for which the light-emitting unit 00 illuminates the blue light-emitting device is tb, and the subframe duration for which the light-emitting unit 00 illuminates the blue light-emitting device is tg, then tr>tb≥tg can be set. Since the red light-emitting device has greater energy due to its longer emission wavelength, its heat dissipation and power consumption are greater than those of the green and blue light-emitting devices. Therefore, in the timing switching cycle of a display stage F, the subframe duration Tr for which the light-emitting unit 00 illuminates the red light-emitting device can be longer. Then, within each subframe, when the brightness of the red light-emitting device is controlled by the duty cycle, the duty cycle can be appropriately increased to compensate for the energy loss caused by the insufficient illumination time of the red light-emitting device, thereby helping to reduce the temperature of the red light-emitting device, extend its lifespan, effectively reduce power consumption, and achieve better heat dissipation.

[0064] In some alternative embodiments, please refer to the references. Figure 1 , Figure 11 and Figure 18 , Figure 18 The light-emitting panel of this embodiment adopts Figure 11 A schematic diagram illustrating the principle of the switching sequence of the light-emitting colors of the light-emitting units. In this embodiment, the light-emitting panel 000 includes multiple light-emitting zones RC, and each light-emitting zone RC includes at least one light-emitting unit 00. It is understood that this embodiment... Figure 18 The example shown is RC, which includes a light-emitting unit 00. Figure 18 The diagram illustrates the adoption of Figure 11The switching sequence of the light emission colors of the light-emitting units is illustrated in the diagram below, showing the light emission colors of the light-emitting panels in each of the nine subframes sf (subframe 1 f11, subframe 2 f12, subframe 3 f13, subframe 4 f21, subframe 5 f22, subframe 6 f23, subframe 7 f31, subframe 8 f32, and subframe 9 f33) within a display stage F. Figure 18 As shown, in a display stage F, under the same subframe, at least three adjacent light-emitting units 00 emit different colors in the first direction X. The first direction X can be understood as the horizontal direction of the light-emitting panel 000 in the figure.

[0065] Optionally, in a display stage F, under the same subframe, the light emission colors of three adjacent light-emitting units 00 in the second direction Y are different; wherein, in the direction parallel to the plane where the light-emitting panel 000 is located, the first direction X and the second direction Y are perpendicular to each other.

[0066] Optionally, in a display stage F, under the same subframe, the light emission colors of three adjacent light-emitting units 00 on the third direction J are different; wherein, in the direction parallel to the plane where the light-emitting panel 000 is located, the angle between the third direction J and the first direction X is an acute angle, and the angle between the third direction J and the second direction Y is an acute angle.

[0067] This embodiment explains the switching order of the light-emitting colors of the light-emitting units in a display stage F using the above embodiment. It can achieve that, within the same subframe, not only are the light-emitting colors of any three adjacent light-emitting units 00 along the first direction X of the light-emitting panel different, but also the light-emitting colors of any three adjacent light-emitting units 00 along the second direction Y of the light-emitting panel are different. Furthermore, it can also achieve that the light-emitting colors of any three adjacent light-emitting units 00 along the third direction J are different. If the light-emitting panel 000 is divided into multiple light-emitting zones RC, and each light-emitting zone RC includes a light-emitting unit 00, then each of three adjacent light-emitting zones RC will have red (R), green (G), or blue (B) colors respectively. In addition, by combining spatial alternation layout, RGB color mixing can be achieved in adjacent spaces. This not only breaks the visual impact caused by the continuity of the same RGB light-emitting order between different subframes of a display stage F, realizing direct temporal color mixing of the three light sources, but also spatial color mixing, thereby more effectively solving the color separation problem.

[0068] In some alternative embodiments, please continue to refer to the references. Figure 1 , Figure 11 and Figure 18 In this embodiment, the light-emitting panel 000 includes multiple light-emitting zones RC, and each light-emitting zone RC includes a light-emitting unit 00, thereby increasing the number of light-emitting zones in the light-emitting panel 000 and enabling more precise local dimming.

[0069] In this embodiment, three adjacent light-emitting units 00 include a first light-emitting unit 00A, a second light-emitting unit 00B, and a third light-emitting unit 00C; within the same subframe group of a display stage F: For the first light-emitting unit 00A, the switching order of the light-emitting colors is the first order; For the second light-emitting unit 00B, the switching order of the light-emitting colors is the second order; For the third light-emitting unit 00C, the switching order of the light-emitting color is the third order; The first, second, and third orders are all different.

[0070] This embodiment explains the use of a light-emitting panel. Figure 11 Taking the switching sequence of the light emission colors of the light-emitting units as an example, the light emission colors of the light-emitting panels in each of the nine subframes of a display stage F can be as follows: Figure 18 As shown. Within the same subframe group of a display stage F, for the first light-emitting unit 00A, the switching order of the light-emitting colors is the first order; for the second light-emitting unit 00B, the switching order of the light-emitting colors is the second order; and for the third light-emitting unit 00C, the switching order of the light-emitting colors is the third order, and the first, second, and third orders are all different. Specifically: like Figure 18 and Figure 19 As shown, Figure 19 yes Figure 18The diagram illustrates the color switching of three adjacent light-emitting units in the first direction during a display phase. In the first subframe group f1 (first subframe f11, second subframe f12, third subframe f13) of a display phase F, the three adjacent light-emitting units 00 in the first direction X are the first light-emitting unit 00A, the second light-emitting unit 00B, and the third light-emitting unit 00C. For the first light-emitting unit 00A, the color switching order of the light emission in the first subframe group f1 is the first order, i.e., RGB. For the second light-emitting unit 00B, the color switching order of the light emission in the first subframe group f1 is the second order, i.e., GBR.

[0073] This embodiment explains the switching order of the light-emitting units in a display stage F using the above embodiment. It can realize that the switching order of three adjacent light-emitting units in any direction is different in the same subframe group of a display stage F. This not only breaks the visual impact caused by the continuity of the same RGB light emission order between different subframes of a display stage F, and realizes the three-color light source to directly mix colors in time, but also realizes color mixing in space. This can more effectively solve the color separation problem and improve the visual effect.

[0074] In some alternative embodiments, please refer to Figure 22 , Figure 22This is a schematic diagram of a display device provided in an embodiment of the present disclosure. The display device 222 provided in this embodiment includes the light-emitting panel 000 of any of the above embodiments. It can be understood that... Figure 22 The illustration uses a mobile phone as an example for the display device 222. The display device 222 provided in this embodiment can be any other display device 222 with display functions, such as a computer, television, or vehicle-mounted display device. This invention does not impose specific limitations on this. The display device 222 provided in this embodiment has the beneficial effects of the light-emitting panel 000 provided in this embodiment. For details, please refer to the specific descriptions of the light-emitting panel 000 in the above embodiments; these will not be repeated here.

[0075] In some alternative embodiments, please refer to Figure 23 , Figure 23 This is another structural schematic diagram of the display device provided in this embodiment. The display device 222 provided in this embodiment includes a light-emitting panel 000 of any of the above embodiments and a liquid crystal panel 111 located on the light-emitting surface side of the light-emitting panel 000. In this embodiment, the light-emitting panel 000 is used as a backlight module. The liquid crystal panel 111 includes an array substrate 111X, a liquid crystal layer 111Y and a colorless resist substrate 111G.

[0076] Optionally, the display device 222 in this embodiment may also include a data control generator 333, a timing control unit 444, and a backlight controller 555 electrically connected to the liquid crystal panel 111 and the light-emitting panel 000. When the display device 222 displays, an external image signal is input to the data control generator 333. The data control generator 333 performs preprocessing such as format conversion and encoding on the signal to provide basic data for subsequent driving and backlight control. For example, after the image signal is input, the data control generator 333 decomposes the image information into red, green, and blue (RGB) grayscale data components and transmits them to the backlight controller 555, which controls the light-emitting panel 000 of the backlight module to emit red, green, and blue (RGB) light sequentially in time. After the image signal is input, it is decomposed into timing signals by the data control generator 333 and output to the timing control unit 444. The timing control unit 444 generates precise timing signals to control the data driver circuit 111A and the gate driver circuit 111B of the liquid crystal panel 111 respectively. The gate driver circuit 111B selects the liquid crystal pixel rows one by one, and the data driver circuit 111A applies the corresponding data voltage to the selected pixel rows to control the light transmittance of the liquid crystal pixels. Finally, with the help of the persistence of vision of the human eye, the RGB three colors of light and the light transmittance control of the liquid crystal pixels are switched synchronously and quickly. The human eye perceives these three colors mixed together and finally forms a color image. The display device 222 of this embodiment uses time-separated color and visual persistence to control the RGB backlight to emit light in a time-separated manner through the light-emitting panel 000 as a backlight module. The liquid crystal panel 111 without color filters acts as a pixel switch to quickly switch data signals within a specific period. By utilizing the visual persistence effect of the human eye, the three light sources can be directly mixed in time, eliminating the need for color filters in traditional liquid crystal displays. In this embodiment, the liquid crystal panel 111 is equipped with a color-free substrate 111G corresponding to the array substrate 111X. By using the backlight timing to switch the RGB three colors and coordinating with the liquid crystal pixels to synchronously control the light, a color display effect is achieved, which has higher brightness and color gamut.
