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 present invention discloses an organic light -emitting display panel, its testing method and device and its display method. By setting the gray level of the display screen of the organic light -emitting display panel;When the setting of the order brightness is switched to other screens without residual shadows, determine the current data signal voltage value corresponding to the current maximum gray order; according to the determined data signal voltage value and the highest gray order brightness, determine the valid pulse of the light control signal to occupy the duty kitchenThe ratio; according to the determined valid pulse occupation ratio and the setting of the other ash levels set, determine the voltage value of the data signal corresponding to the other ash gradients;The corresponding data signal voltage value.While changing the voltage value of the data signal to eliminate the display residual, the valid pulse occupation ratio of the lighting control signal is adjusted to adjust the lighting time of the display panel, so as to achieve the brightness set by each gray level.

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...
