Embodiment 1
[0035] figure 1 A flowchart showing a method for adjusting brightness of a liquid crystal display according to an embodiment of the present invention. Such as figure 1 As shown, the method may mainly include step S100, step S200 and step S300, each step will be described in detail below.
[0036] Step S100 , determining the pixels in the display panel of the liquid crystal display that need to be switched in gray scale as the pixel area to be processed.
[0037] For example, when the image displayed on the display panel of the liquid crystal display changes, for example, the display panel switches from displaying a black background to displaying a white image, it may be necessary to increase the brightness of some pixels, and the area where these pixels are located is The area of pixels to be processed. Specifically, it is necessary to switch the pixels in the pixel area to be processed from the first grayscale d1 to the second grayscale d2, wherein the first grayscale ...
Embodiment 2
[0044] figure 2 A flowchart showing a method for adjusting brightness of a liquid crystal display according to another embodiment of the present invention. Such as figure 2 as shown, figure 2 The brightness adjustment method shown with the figure 1 The main difference in the brightness adjustment methods shown is that figure 1 The brightness adjustment method mainly includes step S100, step S200 and step S300, and figure 2 The brightness adjustment method mainly includes step S100, step S200, step S310 and step S320. figure 2 Winning mark and figure 1 The same steps, that is, step S100 and step S200 have the same function, for the sake of brevity, the detailed description of these two steps is omitted, and the detailed description of step S310 and step S320 is mainly given.
[0045] Step S310 is executed after step S200, and the display area corresponding to the area to be dimmed in the display panel is determined as the display area to be processed according to ...
Embodiment 3
[0054] Figure 4 A flowchart showing a method for adjusting brightness of a liquid crystal display according to yet another embodiment of the present invention. Such as Figure 4 as shown, Figure 4 The brightness adjustment method shown is figure 1 A possible specific implementation of the brightness adjustment method shown. Figure 4 Winning mark and figure 1 The same steps, that is, step S100 and step S200 have the same function, for the sake of brevity, the detailed description of these two steps is omitted, and the detailed description of step S311 and step S321 is mainly given.
[0055] Such as Figure 4 As shown, in a possible implementation manner, step S300 may include: step S311, using formula 1 to calculate the brightness value of the area to be dimmed at time t,
[0056] A ( t ) = A m ...
