Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.
Due to design cost and requirement of the internal function processing module, the display panel can adopt a 6-bit input/output driving circuit, and the actual display gray scale is 26I.e., 64 gray levels. For image data input with a high number of bits (for example, 8 bits or 10 bits, etc.), it may be conventional to discard the lower data components, but such a procedure may result in a reduction in image display effect.
In addition, the display panel may further distribute each sub-pixel in time and space by a Frame Rate Conversion (FRC) driving method, and obtain a pixel average by using a single pixel that cannot be resolved by human eyes and an image that cannot be discriminated to rapidly change a single Frame, so as to increase the gray scale number of each pixel unit. That is, by properly controlling the frame rate and by controlling the colors between adjacent pauses to a certain degree, the colors that the display panel cannot originally display can be seen, so that the image information with a higher number of bits can be displayed with a lower number of bits, and the image display effect is not affected substantially. The application provides a driving method and a driving device for driving a display panel, which can greatly increase the number of gray scales that the display panel can display and improve the display effect of the display panel.
Referring to fig. 1 and fig. 2, an embodiment of the present application provides a driving method and a driving apparatus for a display panel, where the driving method can be implemented by the driving apparatus to drive the display panel to perform driving, each display frame of the display panel includes a plurality of sub-frames, and a duration of each sub-frame is different.
In some embodiments, a driving method includes:
step S1, obtaining gray scale data of pixel unit according to the input image;
step S2, determining the voltage signal of the pixel unit and the display sub-frame for displaying in a plurality of sub-frames according to the gray scale data; and
in step S3, a voltage signal is applied to the pixel cell for the duration of the display sub-frame.
Specifically, the driving apparatus includes an acquisition module, a processing module, and a control module, and step S1 may be implemented by the acquisition module, step S2 may be implemented by the processing module, and step S3 may be implemented by the control module. That is, the obtaining module may be configured to obtain gray scale data of the pixel unit according to the input image. The processing module can be used for determining a voltage signal of the pixel unit and a display subframe for displaying in a plurality of subframes according to the gray scale data. The processing module may be configured to apply a voltage signal to the pixel cell for a display sub-frame duration.
The driving method and the driving device of the display panel can enable the pixel unit to display corresponding real gray scales in the duration time of the whole display frame by controlling the size of the voltage signal, divide each display frame into subframes with different duration time, so that the time of each subframe accounts for different weights of the whole display frame, and can generate corresponding induction gray scales by utilizing visual inertia of human eyes through the combination of different subframes.
It can be understood that the display panel is formed by a plurality of pixel units to jointly display an image, wherein each pixel unit comprises a red pixel, a green pixel and a blue pixel, the red pixel is used for emitting red light, the green pixel is used for emitting green light, the blue pixel is used for emitting blue light, and the red, the green and the blue are mixed in different proportions to form visible light with different colors, so that the display panel can display corresponding colors. In the brightness control of the display panel, the gray scale represents the gradation level of different brightness of the pixels from the darkest to the brightest, and the color of each pixel can be determined by the change of the gray scale. The more the intermediate levels are, the more exquisite the picture effect can be presented. In step S1, when an image is input to the display panel and driven, grayscale data for each pixel unit can be acquired from the input image.
In some embodiments, the Display panel includes, but is not limited to, a Liquid Crystal Display (LCD) Display panel and an organic light-Emitting Diode (OLED) Display panel.
Referring to fig. 3 and 4, in some embodiments, each display frame of the display panel includes a first subframe lasting for a first duration, a second subframe lasting for a second duration, a third subframe lasting for a third duration, and a fourth subframe lasting for a fourth duration, wherein the first duration < the second duration < the third duration < the fourth duration.
That is to say, each display frame of the display panel of the embodiment may be divided into 4 subframes, and the display duration of the 4 display frames is different, that is, the weight of the four subframes in the whole display frame is different, so that the number of gray scales that can be displayed by the display panel can be increased, and the display effect of the display panel is improved.
In some embodiments, the display panel sequentially displays the first sub-frame, the second sub-frame, the third sub-frame, and the fourth sub-frame, that is, each sub-frame in the display frame is sequentially driven from small to large according to the duration. In other embodiments, the display panel sequentially displays the fourth sub-frame, the third sub-frame, the second sub-frame, and the first sub-frame, that is, each sub-frame in the display frame is sequentially driven from large to small according to the duration. Of course, in other embodiments, the display order of each subframe may not be limited to the above discussed embodiments, and may be designed according to actual needs, and is not specifically limited herein.
In some embodiments, the ratio of the first duration, the second duration, the third duration, and the fourth duration is 1:2:4: 8.
Specifically, in the case where the display frame is used for display from a total time length of T, the first time length may be T/15, the second time length may be 2T/15, the third time length may be 4T/15, and the fourth time length may be 8T/15. Thus, 2 can be formed by selective display of 4 different sub-frames4Compared with the original driving mode that the display frame is not displayed and the display frame is completely displayed within the duration, 14 induction gray scales realized by frame rate conversion are added between the two real gray scales realized by voltage control, namely the display capability of 4 bit is increased, and the display effect of the display panel is favorably improved.
Four sub-frames of a display frame are encoded, 16 gray scales of 0, 1/15, 2/15, 3/15, 4/15, 5/15, 6/15, 7/15, 8/15, 9/15, 10/15, 11/15, 12/15, 13/15, 14/15 and 1 can be obtained through frame frequency conversion, wherein 0 and 1 corresponding to the display frame are real gray scales, and the rest are sensing gray scales. As shown in the following table, for each sub-frame, 0 may indicate that the corresponding sub-frame does not drive the pixel unit for the duration, and 1 may indicate that the corresponding sub-frame drives the pixel unit for the duration, and accordingly, in step S2, the processing module may determine the display sub-frame for display according to the gray scale data and the corresponding code.
In one example, the display panel can be driven by a data driving chip with 6bit digits, 946 induction gray scales can be increased by selecting and displaying through 4 subframes with different time lengths, which is equivalent to increase the display capability of 4 bit digits, namely, the display effect of 10 bit digits can be achieved, so that the picture displayed by the display panel is finer and smoother.
In other embodiments, each display frame may not be limited to 4 subframes, and may adopt 2 subframes, 3 subframes, or more than 4 subframes according to actual needs, which is not specifically limited herein.
It should be noted that the ratio of the durations of the plurality of subframes in each display frame from small to large may be an equal ratio sequence with a first term of 1 and a common ratio of 2. In one example, each display frame includes 2 subframes, and the ratio of the duration of the 2 subframes from small to large may be 1:2, i.e., one subframe lasts for T/3, and the other subframe lasts for 2T/3. In another example, each display frame includes 3 subframes, and the ratio of the duration of the 3 subframes from small to large may be 1:2:4, i.e., the first subframe lasts for T/7, the second subframe lasts for 2T/7, and the third subframe lasts for 4T/7.
In some embodiments, in the case that the number of bits of the input original image data is different from the number of bits that can be displayed by the display panel, step S1 may obtain the gray scale data of the pixel unit according to an algorithm.
For a display panel which is driven by a data driving chip with 6bit number and each display frame comprises four sub-frames with different time lengths, an image with 10 bit number can be displayed, if the input original image data is only 8 bit number, step S1 may obtain the gray scale data of the pixel unit according to an algorithm to increase the gray scale number of the image for driving. Therefore, the display effect of the display panel is improved.
In some embodiments, a driving method includes: and controlling the interval between two adjacent display frames to be driven for a first preset time.
Specifically, the control module can be used for controlling two adjacent display frames to be driven at a first preset time interval.
It can be understood that, for the dynamic picture, the images to be displayed between two adjacent display frame frames may be different, so that the time interval of the first predetermined time duration is increased between two adjacent display frames in the embodiment, thereby avoiding the color crosstalk phenomenon between two adjacent display frames displaying different images and ensuring the display effect of the display panel. In particular, the pixels may be a hold picture during the time interval of two display frames, without being updated.
In some embodiments, a driving method includes: and controlling the interval between two adjacent subframes to drive for a second preset time, wherein the first preset time is longer than the second preset time.
Specifically, the control effect module can be used for controlling the two adjacent sub-frames to be driven at intervals of a second preset duration.
Similarly, the time interval of the second preset duration is added between two adjacent subframes, so that the color cross phenomenon between the two adjacent subframes can be avoided, and the display effect of the display panel is ensured. The pixels may be a hold picture during the time interval of two sub-frames and are not updated.
In one example, the display panel may refresh the display frames at a frequency of 60Hz, each display frame time may be 16.67mS, where 15mS is displayed, and the first predetermined length of time for the two display frame intervals may be 1.67 mS. Each display frame may include 4 subframes, and the 4 subframes may last for a total of 15mS, wherein the first subframe may last for a first duration of 1mS, the second subframe may last for a second duration of 2mS, the third subframe may last for a third duration of 4mS, and the fourth subframe may last for a fourth duration of 8 mS. The second predetermined duration of two adjacent subframe intervals may be 0.2mS, and the first predetermined duration of two adjacent display frame intervals may be 1.07 mS.
In some embodiments, the display panel includes a liquid crystal display panel, and the driving method includes: and controlling the polarities of the voltage signals applied to the pixel units in the two adjacent display frame durations to be opposite.
Specifically, the control module may be configured to control the polarities of the voltage signals applied to the pixel units in two adjacent display frame durations to be opposite.
In the case of a liquid crystal display panel, applying the same electric field for a long time causes charge accumulation, and metal particles originally dissociated in a liquid crystal layer are shifted to one side, which affects normal rotation of liquid crystal molecules, thereby causing luminance deviation and generating a defective display phenomenon such as an afterimage. Therefore, the display effect of the display panel is ensured by applying opposite polarities to different display frames so as to avoid the polarization phenomenon of liquid crystal.
In some embodiments, the display panel includes a liquid crystal display panel, and the driving method includes: and controlling the polarities of the voltage signals applied to the pixel units in the two adjacent sub-frame durations to be opposite.
Specifically, the control module may be configured to control the polarities of the voltage signals applied to the pixel units in two adjacent sub-frame durations to be opposite.
Similarly, for the liquid crystal display panel, the opposite polarities can be applied through different sub-frames in one display frame so as to avoid the polarization phenomenon of liquid crystal and ensure the display effect of the display panel.
In one embodiment, each display frame may include a first sub-frame, a second sub-frame, a third sub-frame, and a fourth sub-frame, which are sequentially driven, and the control module may be configured to control the duration of the first sub-frame and the third sub-frame to be positive, and the duration of the second sub-frame and the fourth sub-frame to be negative.
Further, in some embodiments, each display frame may include a first sub-frame, a second sub-frame, a third sub-frame, and a fourth sub-frame, which are sequentially driven, and the control module may be configured to control the applied voltage signal to be positive during the first sub-frame and the third sub-frame of the current display frame, and to be negative during the second sub-frame and the fourth sub-frame; and the control unit is used for controlling the duration time of the first sub-frame and the third sub-frame of the next display frame to be negative, and the duration time of the second sub-frame and the fourth sub-frame to be positive.
In some embodiments, the display panel includes a liquid crystal display panel, and the polarities of the applied voltage signals controlling the adjacent two pixel units in the liquid crystal display panel are opposite.
Therefore, the liquid crystal display panel can achieve the best display effect in a dot inversion mode for the same display frame and/or subframe.
Referring to fig. 5, a display device according to an embodiment of the present application includes a processor, a memory, and computer-executable instructions stored in the memory, where the computer-executable instructions are executed by the processor to implement the driving method according to any of the above embodiments.
The display device comprises a processor, a pixel unit, a display panel and a driving chip, wherein the processor is used for executing computer executable instructions, the pixel unit can display corresponding real gray scales in the duration time of the whole display frame by controlling the size of a voltage signal, each display frame is divided into subframes with different duration times, the time of each subframe accounts for different weights of the whole display frame, corresponding sensing gray scales can be generated by visual inertia of human eyes through the combination of different subframes, the number of gray scales which can be displayed by the display panel can be increased under the condition that the bit number of the driving chip is low, and the display effect of the display panel is improved.
In one example, the computer executable instructions when executed by the processor implement the steps of:
step S1, obtaining gray scale data of pixel unit according to the input image;
