Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0055] The terms "first", "second", etc. in the specification and claims of the present application and the above accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0056] Referring to "embodiment" in the present application means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0057] To better understand a sequential color mixing method for effectively improving LCoS flicker and brightness provided by an embodiment of the present application, the LCoS chip system will be briefly introduced below. As Figure 1 shown, the LCoS chip system may include a SOC (system-on-chip), an LCoS chip, a driving module, an LED driving module, and a clock power supply module. Among them,

[0058] The SOC's main function is the decoding output of the video source or the conversion of the video interface, such as HDMI to RGB888 or HDMI to LVDS, etc.;

[0059] The LCoS chip's main function is to receive video data and modulate the transmittance of each pixel's liquid crystal according to the video data, so as to realize the modulation of light and output various images;

[0060] The driving module can be a driving IC chip or an FPGA. Its main function is to receive parallel RGB video data, decompose it into red frames / green frames / blue frames and cache them in the RAM, and then convert them into serial sequential color mixing data and send it to the LCoS chip according to the LCoS timing;

[0061] The LED driving module's main function is to convert the 3-way PWM signal of the LED output by the driving module into a constant-current LED power driving signal;

[0062] The clock power supply module provides clock and power for each voltage for the entire LCoS chip system.

[0063] In the embodiment of the present application, the sequential color mixing method is adopted. The sequential color mixing method is to project three primary color lights onto the same plane in a certain time sequence. When the rotation speed is fast enough, due to the visual inertia of the human eye, the three primary colors cannot be distinguished, and the effect of mixed color is seen.

[0064] Please refer to Figure 2A , Figure 2A which is a schematic flowchart of a sequential color mixing method for effectively improving LCoS flicker and brightness provided by an embodiment of the present application. As Figure 2A shown, applied to the LCoS chip system, the LCoS chip system includes an LCoS chip, and the method includes:

[0065] 201. Receive video data to be displayed.

[0066] Among them, the video data to be displayed can be received through the driving module in the LCoS chip system, and the video to be displayed can be video source data. The video data to be displayed can be any video data that needs to be displayed, and the data format of the video data can be various formats, without specific limitation.

[0067] 202. Decompose the video data to be displayed into frames to obtain multiple color frames corresponding to the video to be displayed, where the multiple color frames include a red frame, a green frame, and a blue frame.

[0068] The method of decomposing the video data to be displayed into frames can adopt the existing frame decomposition method. After decomposing to obtain multiple color frames, store these multiple color frames in the RAM. After receiving and decomposing one frame of data of a complete video data to be displayed, the identification bit of data update can be updated. When decomposing the video data to be displayed, it can be decomposed frame by frame. For example, it can be decomposed according to a complete data frame, and the obtained color frames are stored after decomposition.

[0069] 203. Determine the sequential color mixing information of the multiple color frames, where the number of times the green frame lights up indicated in the sequential color mixing information is higher than that of the blue frame and the red frame.

[0070] The sequential color mixing information of the multiple color frames can be the position information of the sub - frames corresponding to the color frames in the sequential frame. Since the positions of the color frames corresponding to the sub - frames in the sequential frame are different, their display orders are also different. Thus, the position of the sub - frames can be set to improve the display brightness and reduce flicker.

[0071] 204. Perform sequential color mixing on the multiple color frames according to the sequential color mixing information to obtain sequential color - mixed data.

[0072] In the sequential color - mixed data, the color frames are set in the data frame according to the sequence. The setting method can be to set the color frames at the corresponding positions according to the position information of the sub - frames in the sequential color mixing information to obtain the sequential color - mixed data.

[0073] 205. Send the sequential color - mixed data to the LCOS chip to instruct the LCOS chip to display the video data to be displayed.

[0074] The color frames in the data frame can be sent according to the sending order determined by the sequential information of the sequential color - mixed data, and the LCOS chip is instructed to display the data to be displayed.

[0075] In this example, by receiving the video data to be displayed, frame decomposition is performed on the video data to be displayed to obtain multiple color frames corresponding to the video to be displayed. The multiple color frames include a red frame, a green frame, and a blue frame. The sequential color mixing information of the multiple color frames is determined. The number of times the green frame lights up indicated in the sequential color mixing information is higher than that of the blue frame and the red frame. According to the sequential color mixing information, the multiple color frames are sequentially color-mixed to obtain sequential color mixing data, and the sequential color mixing data is sent to the LCOS chip to instruct the LCOS chip to display the video data to be displayed. Therefore, when performing sequential color mixing, the number of times the green frame lights up indicated in the color mixing information is higher than that of the blue frame and the red frame, the display frequency of the green frame is higher, the occurrence of flicker can be reduced, and at the same time, compared with the RGBRGB mode, the turn-on delay can be reduced and the display brightness can be improved. Among them, the RGBRGB mode can reduce the occurrence of flicker, but it has a 6-time turn-on time delay, and its turn-on time delay is relatively high. In this application, the number of times the green frame lights up is higher than that of the blue frame and the red frame, and the total number of times it lights up is 4 times, so 2 times of turn-on time delay can be reduced and the display brightness can be improved.

[0076] In a possible implementation manner, a possible method for determining the sequential color mixing information of the multiple color frames includes:

[0077] A1. Determine multiple first sub-frames corresponding to the red frame in the multiple color frames in one timing frame;

[0078] A2. Determine multiple second sub-frames corresponding to the green frame in the multiple color frames in one timing frame;

[0079] A3. Determine multiple third sub-frames corresponding to the blue frame in the multiple color frames in one timing frame;

[0080] A4. Determine the sequential color mixing information for the multiple color frames according to the timing position information of the first sub-frame, the second sub-frame, and the third sub-frame.

[0081] Among them, the above steps A1, A2, and A3 are not executed in a sequential order and can be executed simultaneously. The above simultaneous execution can be understood as being able to be executed simultaneously when determining the sequential color mixing information, but when performing sequential transmission, it is transmitted according to the corresponding timing and cannot be executed simultaneously.

[0082] As Figure 2B shown, Figure 2BA timing diagram showing the temporal color mixing of multiple color frames is presented. In Figure 2, VS is the synchronization signal of the LCOS chip, field is the segment of different sub-frames of the timing frame, the brightness region is the time period when different color LED lights are on, led_r is the lighting time of the red frame, led_g is the lighting time of the green frame, and led_b is the lighting time of the blue frame.

[0083] Among them, the red frame corresponds to the first and second sub-frames in the timing frame, the green frame corresponds to the third and sixth sub-frames in the timing frame, and the blue frame corresponds to the fourth and fifth sub-frames in the timing frame. The first G frame shown in Figure 2 is the last sub-frame of the previous data frame, and its starting sub-frame in a complete timing frame is the red frame (R frame), and its temporal color mixing can be expressed as RRGBBG.

[0084] As Figure 2B shown, the green frame among multiple color frames corresponds to 2 lighting delays, the red frame among multiple color frames corresponds to 1 lighting delay, and the blue frame among multiple color frames corresponds to 1 lighting delay.

[0085] Therefore, it can be seen from Figure 2B that in a timing frame, the green frame lights up 2 times, which is equivalent to doubling the frame rate, effectively reducing flicker, and there are only 4 ineffective waiting delays. Compared with the 3 waiting delays corresponding to the maximum brightness in the existing scheme, only 1 waiting delay is increased, and the brightness reduction is small at this time. Without changing the hardware conditions, this scheme can effectively reduce flicker, and at the same time can maintain a relatively high brightness, improving the display effect.

[0086] In a possible implementation manner, a method for sending the temporal color mixing data to the LCOS chip to instruct the LCOS chip to display the video data to be displayed includes:

[0087] B1. Determine the sending order of multiple color frames in the temporal color mixing data according to the timing information of the temporal color mixing data;

[0088] B2. When a pulse arrives, send multiple color frames in the temporal color mixing frame to the LCOS chip according to the sending order to instruct the LCOS chip to display the video data to be displayed.

[0089] Among them, the sending order of the color frames is the same as the order of the corresponding sub-frames in the timing information.

[0090] A specific process of a method for sending temporal color mixing data can be as Figure 2C shown, and this sending method can specifically be:

[0091] When the pulse signal utdateFlag waiting for the R / G / B frame update is set to 1, reset the internal sub-frame count SubId = 0, set SubId = SubId + 1, output a synchronization signal vs to the LCOS chip, and update the liquid crystal state with the data in the previous frame (the liquid crystal is the liquid crystal in the LCOS chip) at the same time. Then send the R frame (red frame) data to the LCOS chip. After sending the R frame data, wait for the preset in-frame waiting time (T_hold[1]); when T_hold[1] arrives, set SubId = SubId + 1, send the second synchronization signal vs to the LCOS, and update the liquid crystal state with the data in the previous frame (the liquid crystal is the liquid crystal in the LCOS chip) at the same time. Then send the R frame data to the LCOS chip. The subsequent sending method is the same as the previous steps, and SubId = SubId + 1 after each sending. When the value of SubId is 5, the sending of this data frame is completed, and then the sending of the next data frame is executed.

[0092] In a possible implementation manner, the embodiment of the present application further provides an LED on / off driving method, specifically as Figure 2D shown, including the following steps:

[0093] D1. After power-on, after detecting the synchronization signal Vs of the internal sub-frame, reset the LedCnt counter, and at the same time load the on-delay time of this sub-frame into LedOnDly, and load the off-time into LedOffTime;

[0094] D2. Increment the counter LedCnt++. When LedCnt >= LedOnDl, turn on the LED, LedOD = 1;

[0095] D3. Increment the counter LedCnt++. When LedCnt >= LedOffTime, turn off the LED, LedOD = 0. Then return to step E1 for execution.

[0096] Among them, it is assumed that LedOn is an internal switch signal.

[0097] Through the above method, the driving of the LED on / off can be completed. Among them, as for which color and which sub-field of the LED needs to be turned on, it is necessary to configure the LED enable signal corresponding to the color and the sub-field to 1. For example, if it is necessary to turn on the red LED in the 3rd and 4th sub-frames, then the enable bits that need to be configured are RLedEn_3 = 1, RLedEn_4 = 1. If the LED is not turned on in other sub-frames, then RLedEn_0 = 0, RLedEn_1 = 0, RLedEn_2 = 0, RLedEn_5 = 0. Similarly, configure the enable parameters of other G and B color lights.

[0098] Consistent with the above embodiment, please refer toFigure 3 , Figure 3 is a schematic structural diagram of a chip provided by an embodiment of the present application. As Figure 3 shown, the chip includes a processor and a memory, and the processor and the memory are interconnected. Among them, the memory is used to store a computer program, and the computer program includes program instructions. The processor is configured to call the program instructions, and the processor is configured to call the program instructions. The above program includes instructions for performing the following steps;

[0099] Receive video data to be displayed;

[0100] Perform frame decomposition on the video data to be displayed to obtain a plurality of color frames corresponding to the video to be displayed. The plurality of color frames include a red frame, a green frame, and a blue frame;

[0101] Determine the time-sequential color mixing information of the plurality of color frames. The number of times the green frame is lit indicated in the time-sequential color mixing information is higher than the number of times the blue frame and the red frame are lit;

[0102] Perform time-sequential color mixing on the plurality of color frames according to the time-sequential color mixing information to obtain time-sequential color mixing data;

[0103] Send the time-sequential color mixing data to the LCOS chip to instruct the LCOS chip to display the video data to be displayed.
