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 and device for mending the hue error of an OLED display panel, and a display device. Ageing is carried out on all the monochromatic luminescent devices in the OLED display panel; the aged monochromatic luminescent devices are subjected to a luminescence lifetime attenuation test, the luminescence lifetime attenuation rates corresponding to the monochromatic luminescent devices are obtained; when it is determined that the difference between every two luminescence lifetime attenuation rates of the monochromatic luminescent devices is larger than a preset threshold, the monochromatic luminescent device with the largest luminescence lifetime attenuation rate is aged again till the difference between every two luminescence lifetime attenuation rates of the monochromatic luminescent devices is smaller than the preset threshold. Therefore, the initial service life of all the monochromatic luminescent devices can be rapidly consumed, the problem of residual images in the initial stage of usage is mended, and meanwhile, the lifetime attenuation rates of the monochromatic luminescent devices become slow and consistent so that hue error which happens to displayed images after an OLED display product is used for a long time can be mended.

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 ...
