Abstract

The embodiment of the invention discloses a method for determining aperture opening ratio of an OLED display panel, which not only considers the maximum value of the aperture opening ratio preset by the display panel, the minimum value of the aperture opening ratio of a preset sub-pixel, and the luminance of a first light emitting unit, a second light emitting unit and a third light emitting unitbut also considers the difference of luminance decay speeds of the first light emitting unit, the second light emitting unit and the third light emitting unit at different times of application, thereby obtaining a first luminance decay curve by adjusting the luminance decay speeds of the first light emitting unit, the second light emitting unit and the third light emitting unit in advance and setting the aperture opening rate of each sub-pixel in the display panel based on the first luminance decay curve obtained after the adjustment so as to reduce the luminance difference of the first lightemitting unit, the second light emitting unit and the third light emitting unit in the process of application of the display panel, relieve the color shift phenomenon of the display panel in the process of application, and prolong the service life of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for determining the aperture ratio of an OLED display panel. Background technique [0002] With the development of display technology, color AMOLED (abbreviation of Active-matrix Organic Light Emitting Diode, active-matrix organic light-emitting diode or active-matrix organic light-emitting diode) display panels are more and more applied to mobile phones and tablets. , TV and other electronic display fields. However, the service life of the existing AMOLED display panel needs to be improved. Contents of the invention [0003] In order to solve the above technical problems, an embodiment of the present invention provides a method for determining the aperture ratio of an OLED display panel, so as to prolong the service life of the display panel. [0004] In order to solve the above problems, the embodiments of the present invention provide the following technical solu...
