Abstract

It is display device with time sequence control circuit, programmable voltage generator, grating and source drive circuit and display panel. Wherein the redundant picture element unit and display picture element unit is formed with non-silicon thin film transistor and organic light diode. This invention can compare the working current of each display picture element unit and relative redundant picture element unit. Then the time sequence control circuit can compensate the current of the display unit after working a while according to the comparing results.

Description

technical field

[0001] The invention relates to a detection technology of a display device, in particular to a detection technology of a display device using an organic light emitting diode as a pixel component. Background technique

[0002] Due to the rapid progress of the multimedia society, the technologies of semiconductor components and display devices have also made rapid progress. As far as the display is concerned, since the thin film transistor-active matrix organic light emitting diode (Thin Film Transistor-Active Matrix Organic Light Emitting Diode, hereinafter referred to as TFT-AMOLED) display has no viewing angle limitation, low manufacturing cost, high response speed (about a hundred times that of liquid crystal Above), power saving, can be used for DC drive of portable machines, wide operating temperature range, light weight and can be miniaturized and thinned with hardware equipment, etc., so it meets the characteristic requirements of displays in the multim...
