Embodiment Construction

[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] The main solution of the embodiment of the present invention is: when it is detected that the AMOLED display panel is powered on, time the first continuous power-on duration of the display panel; according to the first continuous power-on duration, obtain the corresponding TFT Each gray scale compensation value; adjusting the driving current of each corresponding TFT on the display panel according to each gray scale compensation value.

[0050] In the prior art, most of the current sub-circuits are constructed based on the TFT of AMOLED pixels to correct the temperature drift of the TFT, such as 4T2C, 6T1C, etc.; it has a better effect when the temperature drift of the TFT is small, but it cannot be used when the drift is large. Processing, and the construction of sub-circuits is difficult and costly, resulting...

Abstract

The invention discloses a method for eliminating afterimages in AMOLED display. When it is detected that the AMOLED display panel is powered on, the first continuous power-on duration of the display panel is counted; according to the first continuous power-on duration, the corresponding Each gray-scale compensation value of each TFT; and determine each specific gray-scale compensation value of each TFT according to different gray scales, and compensate each TFT according to each gray-scale compensation value, thereby adjusting to reach the corresponding each of the display panel. The drive current of the TFT ensures that the drive current flowing through the TFT remains constant. The invention also discloses a display terminal and a computer-readable storage medium. The present invention solves the problem of AMOLED display afterimage by using low-cost and simple implementation.

Description

technical field [0001] The invention belongs to the technical field of plane display, and in particular relates to an AMOLED display residual image elimination method, a display terminal and a storage medium. Background technique [0002] OLED, that is, Organic Light-Emitting Diode (Organic Light-Emitting Diode), is divided into AMOLED (Active-matrix organic light-emitting diode, active matrix organic light-emitting diode) and PMOLED (Passive-Matrix organic light-emitting diode, passive OLED ), OLED display technology has the characteristics of self-luminescence, using very thin organic material coating and glass substrate, when there is current passing through, these organic materials will emit light; while AMOLED has faster response speed, higher contrast ratio, and wider viewing angle. wide, and can save power, etc., and has been more and more used in the displays of TVs, mobile phones, and digital cameras. [0003] AMOLED is a current-driven device, and each AMOLED pixe...
