A display method and display device

Abstract

The invention discloses a display method and a display device, and the method aims at any pixel in a display panel, and comprises the steps: obtaining the input gray scale of the pixel; Judging a display partition where the pixel is located, and calling a conversion matrix corresponding to the display partition, Wherein the conversion matrix is used for converting the color gamut of the display partition into a unified color gamut of the display panel, and the unified color gamut of the display panel is the intersection of the actual color gamuts of the display partitions of the display panel;Obtaining an output gray scale of the pixel according to the conversion matrix and the input gray scale; And controlling the pixel to emit light according to the output gray scale. The display partition converts the color gamut into a consistent uniform color gamut through a conversion matrix; According to the display panel and the display device, all the display partitions on the display panel have the same uniform color gamut, so that the color uniformity of the display panel is improved, and the color display of the full display panel is more accurate due to the fact that all the display partitions have the same uniform color gamut, so that the display quality of a picture can be ensured when a complex picture is displayed.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display method and a display device. Background technique [0002] Color uniformity is one of the important criteria to measure the quality of display panels. Taking the active-matrix organic light emitting diode (AMOLED) display panel as an example, the AMOLED display panel is a display panel that uses OLED devices evaporated on a TFT substrate circuit to achieve self-illumination to achieve picture display. Power consumption, high contrast ratio, wide color gamut, wide viewing angle, wide operating temperature range, fast response time, and can be made into foldable, rollable flexible form and many other advantages. However, due to the limitations of the process, the actual production of AMOLED display panels often cannot guarantee that the device performance of the R / G / B sub-pixels (sub-pixel) in each pixel (pixel) is exactly the same, and when the performanc...

However, due to the limitations of the process, the actual production of AMOLED display panels often cannot guarantee that the device performance of the R / G / B sub-pixel (sub-pixel) in each pixel (pixel) is exactly the same, and when the performance difference reaches a certain level, it will cause R / G / B monochromatic color uniformity is poor, and the color gamut of different pixels is inconsistent, which affects the normal display of the picture

[0003] In order to improve the color uniformity of the display panel, the existing compensation methods often only compensate for a single white picture, so this compensation method cannot guarantee the display quality of complex pictures
