Embodiment Construction

[0036] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] see figure 1 , figure 1 A flowchart of an OLED compensation method provided by an embodiment of the present invention, the OLED compensation method includes steps S11-S13:

[0038] S11 , judging whether the pixel on the panel has a degree of brightness attenuation reaching a preset threshold of initial brightness.

[0039] In this embodiment, the attenuation degree of the R / G / B three-color OLED device is estimated by using the basic method of display data counting, and then the color shift under the current attenuation degree is obtained by calculation (the change of the R / G / B brightness ratio) , first determine whether it reaches the brightness compensation threshold (compensation starting point). For example...

Abstract

The invention discloses an OLED (Organic Light Emitting Diode) compensation method, a compensation device and a display device. The OLED compensation method comprises the following steps: judging whether pixels on a panel have a preset threshold value of which the brightness attenuation degree reaches initial brightness or not; if the pixel with the brightness attenuation degree reaching the preset threshold value of the initial brightness exists, carrying out brightness compensation on each pixel on the panel; and if the pixel of which the brightness attenuation degree reaches the preset threshold of the initial brightness does not exist, compensating the color cast of the OLED. According to the invention, color cast correction and display effect optimization are completed while brightness compensation is realized, the color cast problem caused by inconsistent attenuation degrees of R / G / B three-color devices is solved, and the effects of prolonging the service life of a display and maintaining color characteristics are achieved.

Description

technical field [0001] The present invention relates to the technical field of OLED display, and more specifically, relates to an OLED compensation method, a compensation device and a computer-readable storage medium. Background technique [0002] As a new display technology, AMOLED (Active-matrix Organic Light-emitting Diode) display continues to develop and progress to bring more and more abundant display products; due to process and process reasons, the characteristics of the display display are not uniform, and uniformity compensation is required (De-Mura); and in the display process, TFT (Thin Film Transistor) devices or OLED (Organic Light-emitting Diode) devices and other drive units and light-emitting units will have characteristic drift, which will lead to worsening of the unevenness of the display, and it is also necessary to The characteristic drift of the device is detected and compensated; for the characteristic drift of the device in the AMOLED display, the ind...
