[0045] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0046] First, the background technology involved in this application is introduced.

[0047] With the development of liquid crystal materials, some special liquid crystal materials are gradually entering the display field. Compared with silicon-based liquid crystal display materials, this type of special liquid crystal material has ultra-fast electric field response characteristics. Specifically, when an external electric field is applied, the arrangement and orientation of the liquid crystal will change rapidly; when the applied external electric field changes, its internal structure and properties can also remain stable; and when no external electric field is applied, the liquid crystal molecules still have a certain polarization state.

[0048] Generally, for liquid crystal materials, in order to prevent ion accumulation, the A frame or B frame state is required to make the electric field direction at both ends of the liquid crystal constantly change, thereby ensuring that the voltage between the common electrode and the pixel electrode is always in a DC balance state, thereby extending the service life of the liquid crystal. However, the existing display method for silicon-based liquid crystal display materials is not suitable for special liquid crystal materials with ultra-fast electric field response characteristics.

[0049] Specifically, refer to Figure 1As shown in the figure, it is the electro-optical characteristic curve of special liquid crystal material, the horizontal axis is the voltage difference between the pixel electrode and the common electrode, and the vertical axis is the transmittance of the liquid crystal. Among them, the common electrode voltage is generally a fixed value. When the voltage difference between the pixel electrode and the common electrode is greater than zero, this state is generally called the B frame. As the voltage difference increases, the transmittance of the liquid crystal increases; when the voltage difference between the pixel electrode and the common electrode is less than zero, this state is generally called the A frame. As the voltage difference increases, the transmittance of the liquid crystal decreases. For example, when the absolute value of the voltage difference between the pixel electrode and the common electrode is the same, it is expected to display with the electro-optical characteristics corresponding to a certain state (such as A frame or B frame) to achieve a better display effect.

[0050] In response to this problem, the present application proposes a display system, which includes: a driving module, a light signal generating module and a display module. The driving module processes the connected video source according to the current image display mode to generate a processed video signal, and sends the processed video signal to the display module. At the same time, according to the current screen frame rate and the current display driving mode, an AB frame indication signal is generated, and the AB frame indication signal is sent to the light signal generating module, that is, the generated AB frame indication signal is related to the screen frame rate, so that when the absolute value of the voltage difference between the pixel electrode and the common electrode is the same, the electro-optical characteristics corresponding to the target state (i.e., A frame or B frame) indicated by the AB frame indication signal can be displayed to avoid display errors; then, the light signal generating module generates a light control signal according to the AB frame indication signal and the current screen display frame, and sends the light control signal to the display module. Based on the light control signal, the display module determines the video data of the color corresponding to the light control signal from the processed video signal, and displays the video data of the corresponding color, and finally realizes the correct display of different color grayscales.

[0051] The structure of the display system of the present application is described in detail below through multiple embodiments.

[0052] Figure 2 A schematic diagram of the structure of a display system provided in an embodiment of the present application; Figure 2 As shown, the display system 100 includes: a driving module 1 , a light signal generating module 2 and a display module 3 .

[0053] The output end of the driving module is connected to the input end of the light signal generating module and the display module respectively, and the output end of the light signal generating module is connected to the input end of the display module.

[0054] The driving module is used to receive the video source to be displayed, and process the video source according to the current image display mode to generate a processed video signal, and send the processed video signal to the display module; and generate an AB frame indication signal according to the current screen frame rate and the current display driving mode, and send the AB frame indication signal to the light signal generation module. The AB frame indication signal is used to indicate that the display is performed according to the electro-optical characteristics corresponding to the A frame or the B frame.

[0055] Exemplarily, for example, the image display modes include: temporal color display and spatial color display.

[0056] Among them, the display driving methods include: analog driving method and digital driving method. Specifically, the analog driving method converts the input digital voltage signal into an analog voltage signal through a digital-to-analog converter (DAC). The voltage difference between the analog voltage signal and the common electrode signal is the actual voltage across the pixel. By controlling the output voltage of the DAC, the pixel voltage can be controlled, and then the grayscale display control can be achieved. The digital driving method can generally use the SRAM structure to achieve different grayscale displays of pixels. This method controls different grayscales by modulating the on-time of the pixel switch, which is a pulse width modulation (PWM) control method.

[0057] Therefore, in this embodiment, in order to meet the driving mode of the specific circuit in the display module, the driving module needs to generate an AB frame indication signal according to the display driving mode, that is, the generated AB frame indication signal is related to the display driving mode, so that when the absolute value of the voltage difference between the pixel electrode and the common electrode is the same, it can be displayed according to the electro-optical characteristics corresponding to the target state (that is, A frame or B frame) indicated by the AB frame indication signal, thereby avoiding display errors.

[0058] The light signal generating module is used to generate a light control signal according to the current screen display picture frame and the AB frame indication signal, and transmit the light control signal to the display module.

[0059] The screen display frame refers to the frame currently displayed on the screen, for example, the screen display frame is: a red primary color frame, a green primary color frame or a blue primary color frame. Therefore, in order to achieve the correct display of different color grayscales, it is also necessary to combine the current screen display frame with the AB frame indication signal to generate a light control signal, that is, the generated light control signal can be used to match the video data of the correct color.

[0060] The display module is used to control the processed video signal to display according to the light control signal. In this embodiment, the display module is made of a special liquid crystal material with ultra-fast electric field response characteristics.

[0061] In this embodiment, after receiving the processed video signal and the light control signal, the display module can match the video data of the correct color from the processed video signal based on the light control signal. For example, if the light control signal indicates that the LED light of the red primary color is turned on, the video data of the correct color matched is the video data of the red primary color, and the video data of the red primary color is displayed on the screen, thereby achieving the correct display of different color grayscales. Therefore, this solution uses the AB frame indication signal to control the final displayed image to display the state according to the electro-optical characteristics corresponding to the A frame or the B frame, and uses the light control signal generated by the current screen display frame to match the video data of the corresponding color from the processed video signal, thereby achieving the correct display of different color grayscales.

[0062] In summary, an embodiment of the present application provides a display system, which includes: a driving module, a light signal generating module and a display module. The driving module processes the connected video source according to the current image display mode to generate a processed video signal, and sends the processed video signal to the display module. At the same time, according to the current screen frame rate and the current display driving mode, an AB frame indication signal is generated, and the AB frame indication signal is sent to the light signal generating module, that is, the generated AB frame indication signal is related to the display driving mode, so that when the absolute value of the voltage difference between the pixel electrode and the common electrode is the same, the electro-optical characteristics corresponding to the target state (i.e., A frame or B frame) indicated by the AB frame indication signal can be displayed to avoid display errors; then, the light signal generating module generates a light control signal according to the AB frame indication signal and the current screen display frame, and sends the light control signal to the display module. Based on the light control signal, the display module determines the video data of the color corresponding to the light control signal from the processed video signal, and displays the video data of the corresponding color, and finally realizes the correct display of different color grayscales.

[0063] The following embodiments will be used to explain in detail how the driving module generates video data.

[0064] Optionally, the driver module is specifically used to:

[0065] (1) If the current image display mode is sequential color display, the video source is processed according to the sequential color display mode to obtain the grayscale values ​​of the three primary colors in each frame of the video source.

[0066] In this solution, in order to realize the correct display of video data, it is proposed that the video source can be processed according to the image display mode, and the grayscale values ​​of the three primary colors in each frame of the video source can be obtained. The details are as follows:

[0067] Among them, sequential color display utilizes the visual persistence characteristics of the human eye to project the three primary colors (i.e., red primary color R, green primary color G, and blue primary color B) in sequence at the same position on the screen in a specific proportion. As long as the alternation frequency of the red primary color R, green primary color G, and blue primary color B is high enough, the image perceived by the human eye is a color effect mixed with the three primary colors (i.e., red primary color R, green primary color G, and blue primary color B).

[0068] In one feasible manner, for example, if the current image display mode is a sequential color display, each frame of the video source is processed according to the sequential color display mode to obtain the grayscale values ​​of the three primary colors in each frame of the video source, namely, the grayscale value of the red primary color R, the grayscale value of the green primary color G, and the grayscale value of the blue primary color B.

[0069] (2) If the current image display mode is spatial color display, the video source data is processed according to the spatial color display mode to obtain the three primary color grayscale values ​​of each pixel in each frame of the video source.

[0070] Among them, spatial color display is to use multiple sub-pixels of different colors to form one color pixel on the display screen, and use the visual characteristics of the limited spatial resolution of the human eye to make the sub-pixel distance smaller than the spatial resolution distance of the human eye, so that what is finally seen is a mixture of the three primary colors of RGB.

[0071] In another achievable manner, for example, if the current image display mode is spatial color display, each frame of the video source can be processed according to the spatial color display mode to obtain the three primary color grayscale values ​​of each pixel in each frame of the video source.

[0072] First, taking sequential color display as an example, it specifically explains how the driving module generates a control signal, namely, the AB frame indication signal, and how the light signal generating module generates a light control signal according to the AB frame indication signal.

[0073] Optionally, refer to Figure 3 As shown, the driving module is specifically used for:

[0074] If the current image display mode is sequential color display, the current screen display frame is determined to be a red primary color, a green primary color, or a blue primary color, which can be recorded as R, G, or B;

[0075] The first AB frame indication signal when the current screen display picture frame is red primary color, the second AB frame indication signal when the current screen display picture frame is green primary color, and the third AB frame indication signal when the current screen display picture frame is blue primary color are determined respectively.

[0076] Therefore, the AB frame indication signals of the different primary color frames displayed sequentially on the screen can be determined according to the current screen display frame. For example, the first AB frame indication signal for the red primary color can be determined, so that when the screen displays the red primary color frame, it can be displayed according to the electro-optical characteristics corresponding to the A frame state or the B frame state indicated by the first AB frame indication signal, thereby avoiding display errors.

[0077] Similarly, the second AB frame indication signal for the green primary color can also be determined, so that when the screen displays the green primary color picture frame, it can be displayed according to the electro-optical characteristics corresponding to the A frame state or the B frame state indicated by the second AB frame indication signal. And the third AB frame indication signal for the blue primary color can also be determined, so that when the screen displays the blue primary color picture frame, it can be displayed according to the electro-optical characteristics corresponding to the A frame state or the B frame state indicated by the third AB frame indication signal, thereby achieving the correct display of video data of different primary colors and avoiding display errors.

[0078] Optionally, if the current display driving mode is a digital driving mode, it is determined that the first AB frame indication signal, the second AB frame indication signal and the third AB frame indication signal are all odd multiples of the current screen frame rate.

[0079] In order to meet the specific driving mode of the pixel circuit in the display module, the driving module needs to generate an indication signal of the AB frame according to the display driving mode. Figure 3 As shown, when the current display driving mode is a digital driving mode, it is determined that the first AB frame indication signal, the second AB frame indication signal and the third AB frame indication signal are all odd multiples M of the screen frame rate, such as M=3. M can be any odd number greater than zero. Specifically, the value of M can be determined based on the response time of a special material.

[0080] Optionally, if the current display driving mode is an analog driving mode, it is determined that the first AB frame indication signal, the second AB frame indication signal and the third AB frame indication signal are all integer multiples of the screen frame rate, that is, they can be odd multiples or even multiples.

[0081] In this embodiment, for example, referring to Figure 4 As shown, when the current display driving mode is an analog driving mode, it is determined that the first AB frame indication signal, the second AB frame indication signal and the third AB frame indication signal are all integer multiples N of the screen frame rate, such as N=4, and N can be any integer greater than zero. The value of N is determined specifically according to the response time of a special material.

[0082] Optionally, the light signal generating module is specifically used to:

[0083] A red primary color light control signal is generated according to a preset reference level and a first AB frame indication signal; a green primary color light control signal is generated according to a preset reference level and a second AB frame indication signal; a blue primary color light control signal is generated according to a preset reference level and a third AB frame indication signal.

[0084] For example, the preset reference level is a high level. When the reference level is a high level, a light control signal is generated according to the AB frame indication signal.

[0085] In this embodiment, for example, continue to refer to Figure 3 As shown, the first red primary color picture frame in the current screen display picture frame is taken as an example for explanation. When the reference level is a high level, the red primary color light control signal led(r) is generated as 010 according to the first AB frame indication signal of 010; wherein, the first AB frame indication signal and the red primary color light control signal are both odd multiples of the screen frame rate M, M=3. Specifically, during the time when the current screen display picture frame is a red primary color picture frame, the picture frame displayed on the screen does not change, while the level of the first AB frame indication signal changes 3 times, i.e. 0→1→0, and the level of the red primary color light control signal also changes 3 times, i.e. 0→1→0. In this way, when the current screen display picture frame is a red primary color picture frame, the display module can light up the red primary color LED in the display module based on the red primary color light control signal, thereby realizing the correct display of the red primary color video data.

[0086] Similarly, the first green primary color picture frame in the current screen display picture frame is taken as an example for explanation. When the reference level is a high level, the green primary color light control signal led(g) is generated as 101 according to the second AB frame indication signal of 101; wherein, the second AB frame indication signal and the green primary color light control signal are both odd multiples of the screen frame rate M, M=3. Specifically, during the time when the current screen display timing is the green primary color picture frame, the picture frame displayed on the screen has not changed, while the level of the second AB frame indication signal has changed 3 times, i.e. 1→0→1, and the level of the green primary color light control signal has also changed 3 times, i.e. 1→0→1. In this way, when the current screen display picture frame is a green primary color picture frame, the display module can light up the green primary color LED in the display module based on the green primary color light control signal, thereby realizing the correct display of the green primary color video data.

[0087] And, take the first blue primary color picture frame in the current screen display picture frame as an example for explanation. When the reference level is a high level, the blue primary color light control signal led (b) is generated as 010 according to the third AB frame indication signal of 010; wherein, the third AB frame indication signal and the blue primary color light control signal are both odd multiples of the screen frame rate M, M=3. Specifically, during the time when the current screen display picture frame is a blue primary color picture frame, the screen display picture frame does not change, while the level of the blue AB frame indication signal changes 3 times, i.e. 0→1→0, and the level of the blue primary color light control signal also changes 3 times, i.e. 0→1→0. In this way, when the current screen display picture frame is a blue primary color picture frame, the display module can light up the blue primary color LED in the display module based on the blue primary color light control signal, thereby realizing the correct display of the blue primary color video data.

[0088] Second, taking spatial color display as an example, it specifically explains how the driving module generates a control signal, namely, the AB frame indication signal, and how the light signal generation module generates a light control signal according to the AB frame indication signal.

[0089] Optionally, refer to Figure 5 As shown, the drive module is specifically used for:

[0090] If the current image display mode is spatial color display, then determining that the current screen display frame is a color obtained by mixing three primary colors;

[0091] A fourth AB frame indication signal is used to determine that the current screen display frame is a color obtained by mixing three primary colors.

[0092] For example, refer to Figure 5 As shown, each picture frame displayed on the screen is a color obtained by mixing three primary colors with different proportions.

[0093] In this embodiment, for example, a fourth AB frame indication signal can be generated based on the color obtained by mixing the three primary colors in the current screen display frame, so that when the screen displays the color obtained by mixing the three primary colors, it can be displayed according to the electro-optical characteristics corresponding to the A frame state or the B frame state indicated by the fourth AB frame indication signal, thereby avoiding display errors.

[0094] Optionally, the light signal generating module is specifically used to:

[0095] A white light control signal is generated according to a preset reference level and the fourth AB frame indication signal.

[0096] For example, the preset reference level is a high level. When the reference level is a high level, the white light control signal led(w) is generated according to the fourth AB frame indication signal.

[0097] Optionally, continue to refer to Figure 5 As shown, if the current display driving mode is a digital driving mode, it is determined that the fourth AB frame indication signal and the white light control signal led(w) are both odd multiples M of the screen frame rate, such as M=3. M can be any odd number greater than zero. The value of M can be determined specifically based on the response time of special materials.

[0098] In this embodiment, for example, continue to refer to Figure 5 As shown, the first color after the three primary colors in the current screen display picture frame are mixed as an example for explanation. When the reference level is a high level, the white light control signal led (w) is generated as 010 according to the fourth AB frame indication signal of 010. At the same time, when the current display driving mode is a digital driving mode, the fourth AB frame indication signal and the white light control signal led (w) are both odd multiples of the screen frame rate M, M=3. Specifically, during the time when the current screen display picture frame is the first color picture frame, the picture frame displayed on the screen changes, and the level of the fourth AB frame indication signal changes 3 times, that is, 0→1→0, and the level of the white light control signal also changes 3 times, that is, 0→1→0. In this way, when the current screen display picture frame is the first color, the display module can light up the white light LED in the display module based on the white light control signal, thereby realizing the correct display of the first color video data.

[0099] Optionally, if the current display driving mode is an analog driving mode, the fourth AB frame indication signal and the white light control signal led(w) are determined to be an integer multiple N of the screen frame rate, such as N=2, where N can be any integer greater than zero. The value of N can be determined specifically based on the response time of a special material.

[0100] In this embodiment, for example, referring to Figure 6 As shown, the first color after the three primary colors in the current screen display picture frame are mixed as an example for explanation. When the reference level is a high level, the white light control signal led(w) is generated as 01 according to the fourth AB frame indication signal being 0. At the same time, when the current display driving mode is an analog driving mode, the fourth AB frame indication signal and the white light control signal led(w) are both integers N of the screen frame rate, N=2. Specifically, during the time when the first color in the current screen display picture frame, the picture frame displayed on the screen has not changed, while the level of the fourth AB frame indication signal has changed 2 times, i.e. 0→1, and the level of the white light control signal has also changed 2 times, i.e. 0→1. In this way, when the current screen display picture frame is the first color picture frame, the display module can light up the white light LED in the display module based on the white light control signal, thereby realizing the correct display of the first color video data.
