Problems solved by technology

The difference between the forward transfer characteristic curve and the reverse transfer characteristic curve is obvious especially in the low-middle gray scale range, that is to say, when the pixel switches from the dark state to a certain low-middle gray scale, or switches from the brightness to the same low-middle gray scale mentioned above When the level is high, even if the pixel input is the same data signal corresponding to the middle and low gray scale, when the screen is switched, it will cause the afterimage of the previous frame to appear in the switched screen

Abstract

The invention discloses an organic light-emitting display panel, a testing method thereof, a testing device thereof, and a display method thereof. The brightness of the various gray scales of the display frame of the organic light-emitting display panel is set. When the display frame of the organic light-emitting display panel is switched from the set frame including the highest gray scale brightness to other frames in a trace-free way, a data signal voltage value corresponding to the current highest gray scale is determined. According to the determined data signal voltage value and the highest gray scale brightness, an effective pulse duty ratio of a light-emitting control signal is determined. According to the determined effective pulse duty ratio and the set brightness of other gray scales, the data signal voltage values corresponding to other gray scales are determined. The effectivepulse duty ratio of the determined light-emitting control signal and the data signal voltage values corresponding to the various gray scales are stored. When the data signal voltage values are changed to eliminate display residuals, and the effective pulse duty ratio of the light-emitting control signal is adjusted to adjust the light-emitting time of the display panel, and therefore the brightness set by the various gray scales is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel, a testing method and device thereof, and a display method thereof. Background technique [0002] As a new generation of display devices, organic electroluminescent devices have attracted widespread attention due to their unique characteristics such as self-luminescence, fast response, wide viewing angle and flexible display. Organic Light-Emitting Diode (OLED) is a current-driven active light-emitting display device, which can be divided into passive matrix organic light-emitting diode display device (PM-OLED) and active matrix organic light-emitting diode display device according to the driving method (AM-OLED). The instantaneous high current required by passive driving will lead to defects such as high power consumption and low efficiency, but the use of AM-OLED can overcome the above shortcomings and realize high-resolution and low-po...
