为便于理解本发明，下面将结合图2a至图2c对本实施例公开的图像显示方法进行详细描述。In order to facilitate understanding of the present invention, the image display method disclosed in this embodiment will be described in detail below with reference to FIGS. 2 a to 2 c.
显示驱动芯片内部设置有SRAM，其为存储灰度数据的存储空间，SRAM分为第一存储区A和第二存储区B，第一存储区A和第二存储区B为两个独立的空间。显示驱动芯片接收由接收卡输入的目标视频源，目标视频源例如包括多帧图像，且多帧图像对应的初始帧频例如不完全相同，为了便于说明，多帧图像包括第一帧图像、第二帧图像和第三帧图像，其中第一帧图像对应的第一初始帧频例如为24Hz，第二帧图像对应的第二初始帧频例如为48Hz，第三帧图像对应的第三初始帧频例如为144Hz。接收卡输入到显示驱动芯片的多帧图像为逐帧输入。The display driver chip is internally provided with SRAM, which is a storage space for storing grayscale data. The SRAM is divided into a first storage area A and a second storage area B, and the first storage area A and the second storage area B are two independent spaces. . The display driver chip receives the target video source input by the receiving card. The target video source includes, for example, multiple frames of images, and the initial frame rates corresponding to the multiple frames of images are not exactly the same. Two frames of images and a third frame of images, wherein the first initial frame rate corresponding to the first frame image is, for example, 24 Hz, the second initial frame rate corresponding to the second frame image is, for example, 48 Hz, and the third frame image corresponding to the third initial frame The frequency is, for example, 144 Hz. The multi-frame images input by the receiving card to the display driver chip are input frame by frame.
显示驱动芯片接收由接收卡输入的第一帧图像，并将第一帧图像存入第一存储区A，然后从第一存储区A读取第一帧图像对应的图像数据进行显示，在输出第一帧图像对应的图像数据进行显示的同时，显示驱动芯片接收从接收卡输入的第二帧图像存储至第二存储区B。然后显示驱动芯片在显示完第一帧图像之后从第二存储器B读出第二帧图像对应的图像数据进行显示，与此同时，显示驱动芯片将从接收卡输入的第三帧图像存入第一存储区A。The display driver chip receives the first frame image input by the receiving card, stores the first frame image in the first storage area A, and then reads the image data corresponding to the first frame image from the first storage area A for display. While the image data corresponding to the first frame image is displayed, the display driver chip receives the second frame image input from the receiving card and stores it in the second storage area B. Then the display driver chip reads out the image data corresponding to the second frame image from the second memory B after displaying the first frame image, and at the same time, the display driver chip stores the third frame image input from the receiving card into the second frame image. A storage area A.
具体地，取多帧图像对应的初始帧频的最小公倍数作为显示驱动芯片的最大可支持的帧频即目标帧频。就前述举例而言，目标帧频为144Hz，在显示驱动芯片开始工作前，接收卡将目标帧频对应的显示控制参数通过配置寄存器的方式下发到显示驱动芯片的寄存器中，其中提到的显示控制参数例如包括：灰度时钟频率、消隐时间、每个子场实现的灰度级数以及扫数等参数。Specifically, the least common multiple of the initial frame rates corresponding to the multi-frame images is taken as the maximum supportable frame rate of the display driver chip, that is, the target frame rate. For the aforementioned example, the target frame rate is 144Hz. Before the display driver chip starts to work, the receiving card sends the display control parameters corresponding to the target frame rate to the register of the display driver chip by configuring the register. The display control parameters include, for example, grayscale clock frequency, blanking time, grayscale levels achieved in each subfield, and sweeps.
此外，由于每帧开始时都会首先配置显示驱动芯片的寄存器，接收卡可以通过配置寄存器的方式通知显示驱动芯片当前输入的一帧图像是否进行多次刷新和对应的刷新次数。例如，接收卡取144Hz作为目标帧频，然后将144Hz对应的显示控制参数下发到显示驱动芯片，从而完成显示驱动芯片的准备工作，然后接收卡逐帧输入图像至显示驱动芯片，并输出该图像对应的刷新次数。具体地，接收卡内部例如存储有预设倍频表，参见表1，接收卡基于图像对应的初始帧频从预设倍频表中读取对应的刷新次数下发至显示驱动芯片，如表1所示，预设倍频表例如包括初始帧频、目标帧频以及对应的刷新次数。具体地，预设倍频表的生成过程例如包括：确定输入的目标视频源所包含的多帧图像分别对应的多个初始帧频；将所述多个初始帧频的最小公倍数作为所述目标帧频；以及基于所述目标帧频和每个所述初始帧频确定对应的刷新次数，从而形成所述预设倍频表。以前述举例为例，第一帧图像的第一初始帧频为24Hz，第二帧图像对应的第二初始帧频为48Hz，第三帧图像对应的第三初始帧频为144Hz，因此可以确定目标帧频为144Hz，则计算出第一帧图像对应的第一刷新次数为144/24等于6次，计算出第二帧图像对应的第二刷新次数为144/48等于3次，计算出第三帧图像对应的第三刷新次数为144/144等于1次。In addition, since the register of the display driver chip is first configured at the beginning of each frame, the receiving card can notify the display driver chip whether a frame of image currently input by the display driver chip is refreshed multiple times and the corresponding refresh times by configuring the register. For example, the receiving card takes 144Hz as the target frame frequency, and then sends the display control parameters corresponding to 144Hz to the display driver chip to complete the preparation of the display driver chip, and then the receiving card inputs the image frame by frame to the display driver chip, and outputs the The number of refreshes corresponding to the image. Specifically, for example, a preset frequency multiplier table is stored inside the receiving card, see Table 1, and the receiving card reads the corresponding refresh times from the preset frequency multiplier table based on the initial frame frequency corresponding to the image and sends it to the display driver chip, as shown in the table As shown in 1, the preset frequency multiplier table includes, for example, an initial frame rate, a target frame rate, and the corresponding refresh times. Specifically, the generation process of the preset frequency multiplier table includes, for example: determining multiple initial frame rates corresponding to multiple frames of images included in the input target video source; taking the least common multiple of the multiple initial frame rates as the target frame rate; and determining the corresponding refresh times based on the target frame rate and each of the initial frame rates, thereby forming the preset frequency multiplication table. Taking the foregoing example as an example, the first initial frame rate of the first frame image is 24 Hz, the second initial frame rate corresponding to the second frame image is 48 Hz, and the third initial frame rate corresponding to the third frame image is 144 Hz, so it can be determined that The target frame rate is 144Hz, then the first refresh times corresponding to the first frame image are calculated to be 144/24 equal to 6 times, and the second refresh times corresponding to the second frame image are calculated to be 144/48 equal to 3 times. The third refresh times corresponding to the three frames of images is 144/144 equal to 1 time.
表1预设倍频表Table 1 Preset Octave Table
如图2a所示，显示驱动芯片将输入的第一帧图像存储在第一存储区A之后，接收第一帧图像对应的第一刷新次数为6次，然后显示驱动芯片会在第一初始帧频24Hz对应的时间内重复读第一存储区A中的图像数据进行画面的多次刷新且完成刷新的次数为6次，即重复读6次第一存储区A中的图像数据，由此完成对第一初始帧频进行倍频处理至目标帧频。此时在第一帧图像进行6次完成刷新的过程中，例如在执行第一次完整刷新时将下一帧图像即第二帧图像对应的图像数据存入到第二存储区B。As shown in Figure 2a, after the display driver chip stores the inputted first frame image in the first storage area A, the first refresh times corresponding to receiving the first frame image is 6 times, and then the display driver chip will display the first frame in the first initial frame. Repeatedly read the image data in the first storage area A within the time corresponding to the frequency of 24 Hz to refresh the screen multiple times and the number of times to complete the refresh is 6 times, that is, read the image data in the first storage area A repeatedly 6 times, thus completing The first initial frame rate is multiplied to the target frame rate. At this time, in the process of completing the refresh of the first frame image 6 times, for example, the image data corresponding to the next frame image, that is, the second frame image, is stored in the second storage area B when the first complete refresh is performed.
如图2b所示，显示驱动芯片将第二帧图像存储在第二存储区B且在第一帧图像完成显示之后，显示驱动芯片接收第二帧图像对应的第二刷新次数3次，然后显示驱动芯片重复读第二存储区B中的图像数据进行画面的多次刷新且完成刷新的次数为3次，即重复读3次第二存储区B中的图像数据，由此完成对第二初始帧频进行倍频处理至目标帧频。此时在第二帧图像进行3次完成刷新的过程中，例如在执行第一次完整刷新时将下一帧图像即第三帧图像对应的图像数据存入到第一存储区A。As shown in Figure 2b, the display driver chip stores the second frame image in the second storage area B and after the first frame image is displayed, the display driver chip receives the second refresh times corresponding to the second frame image 3 times, and then displays The driver chip repeatedly reads the image data in the second storage area B to refresh the screen multiple times, and the number of times to complete the refresh is 3 times, that is, the image data in the second storage area B is repeatedly read 3 times, thereby completing the second initial image data. The frame rate is multiplied to the target frame rate. At this time, in the process of completing the refresh of the second frame image three times, for example, the image data corresponding to the next frame image, that is, the third frame image, is stored in the first storage area A when the first complete refresh is performed.
如图2c所示，显示驱动芯片将第三帧图像存储在第一存储区A以覆盖之前保存的图像数据，在第二帧图像完成显示之后，例如接收第三刷新次数为1次，则表示第三帧图像不需要进行多次的刷新，即将第三帧图像存储在第一存储区A之后，读第一存储区 A中的图像数据进行一次画面刷新即可，此时也可以理解为对第三初始帧频进行倍频处理，只是倍频处理的系数为1。As shown in Figure 2c, the display driver chip stores the third frame image in the first storage area A to cover the previously saved image data. After the second frame image is displayed, for example, the number of times of receiving the third refresh is 1, which means The third frame image does not need to be refreshed multiple times, that is, after the third frame image is stored in the first storage area A, the image data in the first storage area A is read and refreshed once. The third initial frame frequency is subjected to frequency multiplication processing, but the coefficient of frequency multiplication processing is 1.
值得一提的是，前述关于接收卡设置预设倍频表以及基于预设倍频表得到刷新次数的步骤也可以在显示驱动芯片的内部实现，前述提到的图像帧数、初始帧频、目标帧频以及刷新次数仅为了更好地理解本实施例。It is worth mentioning that the aforementioned steps of setting the preset frequency multiplier table on the receiving card and obtaining the refresh times based on the preset frequency multiplier table can also be implemented inside the display driver chip. The aforementioned image frame number, initial frame rate, The target frame rate and the number of refreshes are only for better understanding of this embodiment.
综上所述，本实施例公开的图像显示方法通过将输入的第一帧图像存储至第一存储区，并对第一帧图像的第一初始帧频进行倍频处理至目标帧频输出，以及将输入的第二帧图像存储至第二存储区，并对第二帧图像的第二初始帧频进行倍频处理至目标帧频输出，即当图像的初始帧频为低帧频时对该图像的初始帧频进行倍频处理后输出显示，从而通过提高图像帧频来提高对应的低灰刷新率，可以解决现有相关技术在低帧频情况下的低灰刷新率低，导致低灰显示不好的问题，避免在接收卡端进行倍频处理造成的带宽损失，且支持不同帧频切换显示。To sum up, the image display method disclosed in this embodiment stores the input first frame image in the first storage area, and performs frequency multiplication processing on the first initial frame rate of the first frame image to output the target frame rate, And store the input second frame image in the second storage area, and perform frequency multiplication processing on the second initial frame rate of the second frame image to output the target frame rate, that is, when the initial frame rate of the image is a low frame rate, The initial frame frequency of the image is multiplied and then output and displayed, so that the corresponding low-gray refresh rate can be improved by increasing the image frame frequency, which can solve the problem of low low-gray refresh rate in the case of low frame frequency in the prior art, resulting in low The problem of bad gray display can avoid the loss of bandwidth caused by frequency multiplication processing on the receiving card side, and support switching display of different frame rates.
