Embodiment Construction

[0037] The specific implementations of the method, device and display device for improving the color shift of an OLED display panel provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Embodiments of the present invention provide a method for improving the color shift of an OLED display panel, such as image 3 As shown, specifically, the following steps may be included:

[0039] S101. Perform aging treatment on each monochromatic light-emitting device in the OLED display panel;

[0040] S102. Perform a luminous lifetime attenuation test on each of the single-color light-emitting devices after the aging treatment, to obtain the corresponding luminous-lifetime attenuation rates of the monochromatic light-emitting devices;

[0041] S103. Determine whether the difference between the luminous lifetime decay rates of each monochromatic light-emitting device is greater than a preset threshold; if...

Abstract

The invention discloses a method, a device and a display device for improving the color shift of an OLED display panel. The aging treatment is performed on each monochromatic light-emitting device in the OLED display panel; The decay test is used to obtain the corresponding luminous life decay rate of each monochromatic light-emitting device; when it is determined that the difference between the luminous life decay rates of each monochromatic light-emitting device is greater than the preset threshold, the monochromatic luminescence with the fastest luminous life decay rate is determined. The device is subjected to aging treatment again until the difference between the luminous life decay rates of each monochromatic light-emitting device is less than the preset threshold, which can quickly consume the initial service life of each monochromatic light-emitting device and improve the image afterimage that occurs in the early stage of use. At the same time, the lifetime decay rate of each monochromatic light-emitting device becomes flat and tends to be consistent, which can effectively improve the color shift of the display image after long-term use of the OLED display product.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method, device and display device for improving color shift of an OLED display panel. Background technique [0002] With the development of display technology, consumers have higher and higher requirements for audio-visual products. For display manufacturers, the production of high-resolution and high-quality displays is the development direction, while Organic Light Emitting Diode (OLED) ) has been widely used in displays due to its characteristics such as self-illumination, high brightness, wide viewing angle, fast response, and RGB full-color components can be made. At present, the application of OLED display panels has entered the practical stage, and there are already Car audio and mobile phones use OLED display panels. In the future, OLED display panels will be widely used in thin and light displays such as mobile products, notebook computers, monitors, and wall-mounted ...
