Problems solved by technology
However, due to the limitations of LCD panel manufacturing technology or hardware defects, it is easy to cause the LCD produced to fail to achieve the theoretical display effect.
For example, when the same driving signal is input to each pixel of the LCD screen, the luminance and chromaticity of the optical signal output by each pixel are prone to inconsistency, that is, the chromaticity difference and the brightness difference; when the luminance and chromaticity between pixels When the chromaticity difference is greater than the difference range that can be recognized by the human eye, the human eye can easily perceive these bad display effects, causing visual discomfort to the viewer

The embodiment of the invention relates to the technical field of displays, and discloses a screen correction method and device and electronic equipment. The method comprises the steps of obtaining first display parameters of pixel points of at least two display areas of a target screen; wherein the type of the first display parameter comprises a first spectral tristimulus value; according to the first display parameter, determining a target area in the display area and determining a second display parameter of a pixel point of a non-target area in the display area; wherein the target area is the display area, the brightness parameter of which meets a preset requirement, in the display area; the type of the second display parameter comprises a second spectral tristimulus value; converting the brightness parameter into a target display parameter of the second spectral tristimulus value type; and compensating the second display parameter according to the target display parameter. The embodiment of the invention provides a mode for adjusting the display uniformity of the LCD panel.
Description
technical field [0001] The present application relates to the technical field of displays, and in particular, the present application relates to a screen calibration method, device and electronic equipment. Background technique [0002] Liquid Crystal Displays (LCDs) are widely used in the field of displays, for example, in industrial applications, human-computer interaction interfaces of some machines, panels of complex control equipment, displays of medical instruments, and the like. However, due to the limitations of LCD panel manufacturing technology or hardware defects, it is easy to cause the produced LCD to fail to achieve the theoretical display effect. For example, when the same driving signal is input to each pixel of the LCD screen, the luminance and chromaticity of the optical signal output by each pixel are prone to inconsistency, that is, the chromaticity difference and the brightness difference; when the luminance and chromaticity between pixels When the chro...
