Example Embodiment

[0062] Example one

[0063] figure 1 Shows the flow chart of the method for adjusting the brightness of the display screen provided by the first embodiment, such as figure 1 In the first embodiment, the method for adjusting the brightness of the display screen includes the following steps:

[0064] Step 101: Obtain the current brightness value of each pixel of the display screen in a preset grayscale screen; wherein the preset grayscale is any grayscale lower than a preset grayscale threshold.

[0065] For example, the gray scales generally include 256 levels of L0 to L255. In practical applications, the preset gray scales may be gray scales with lower gray scale values ​​such as L0, L1, and L2.

[0066] In this step, it is defined that the preset gray level is any gray level lower than the preset gray level threshold. For example, the preset grayscale threshold may be any one of L6 to L10, and when the preset grayscale threshold is L6, the preset grayscale may be any of L0, L1, L2, L...

Example Embodiment

[0071] Example two

[0072] See figure 2 In this embodiment, after the above step 103, the method for adjusting the brightness of the display screen further includes the following steps:

[0073] Step 104: Determine whether the display effect of the display screen meets the preset display effect; if so, perform step 104a; otherwise, perform step 104b and continue to perform step 104 until the display effect of the display screen meets the preset display effect.

[0074] Step 104a: End the process.

[0075] Step 104b: Re-obtain the current brightness value of each pixel of the display screen in the preset grayscale picture, and re-determine the target brightness value of each pixel, and according to the re-acquired current brightness value of each pixel, and The re-determined target brightness value adjusts the brightness of some or all of the pixels so that each pixel reaches the re-determined target brightness value.

[0076] In this step 104b, the reacquiring the current brightness ...

Example Embodiment

[0083] Example three

[0084] In this embodiment, an implementation manner of step 101 in the foregoing embodiment is given. See image 3 In the above step 101, obtaining the current brightness value of each pixel of the display screen in the preset grayscale image includes the following sub-steps:

[0085] Step a: Set the number of points collected by the CCD camera according to the resolution of the display screen.

[0086] Step b: Use the set CCD camera to collect the current brightness value of each pixel of the display screen.

[0087] In this embodiment, a CCD camera is used to obtain the brightness value of each pixel. For example, set the number of points collected by the CCD camera according to the screen resolution of the display screen, and then use the set CCD camera to collect the current brightness value of each pixel of the display screen, and store the collected current brightness value in the register.

Abstract

The invention provides a display screen brightness adjusting method and system. The method comprises the following steps: obtaining current brightness value of each pixel point of a display screen under a frame in preset gray scale, wherein the preset gray scale is any gray scale lower than a preset gray scale threshold value; determining target brightness value of each pixel point; and carrying out brightness adjustment on a part of or all pixel points according to the current brightness value and the target brightness value of each pixel point to enable each pixel point to reach the target brightness. The display screen brightness adjusting method and system improve uniformity of display brightness of the liquid crystal screen and enable the liquid crystal screen to be able to restore real frame information more accurately.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and system for adjusting the brightness of a display screen. Background technique [0002] At present, LCD screens generally have a relatively obvious defect, that is, under low-brightness screens, the brightness uniformity is poor, so that the LCD screen cannot accurately restore the real screen information, so there is a possibility of misleading the operator. [0003] At present, there is no better solution to this problem. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a method and system for adjusting the brightness of a display screen, which improves the uniformity of the display brightness of the liquid crystal screen, so that the liquid crystal screen can more accurately restore real picture information. [0005] In order to solve the above technical problems, the present invention provides the follow...
