Embodiment Construction

[0069] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0070] figure 1 It is a schematic structural diagram of a detection device of an AMOLED display device provided by an embodiment of the present invention. like figure 1 As shown, the detection device 100 includes a lighting module 110 , a current detection module 120 and a judgment module 130 .

[0071] Wherein, the screen of the AMOLED display device is divided into a plurality of detection areas. The lighting module 110 is used for sequentially lighting a plurality of detection areas of the screen of the AMOLED display device. The current detection module 120 is used to obtain the detection current, and the detection current is the lit detection area (such as figure 2 or image 3 The sum of the driving currents of the light-emitting c...

Abstract

The invention discloses a detection device and method, a repairing device, a repairing method and a repairing system for AMOLED (active matrix organic light-emitting diode) display devices, and belongs to the field of AMOLED display devices. The detection device comprises a lighting module, a current detection module and a judging module; the lighting module is used for sequentially lightning multiple detection areas of a screen of an AMOLED display device, the screen is divided into multiple detection areas, and each detection area includes at least one light-emitting unit; the current detection module is used for acquiring detection current, the detection current is a sum of driving currents of the light-emitting units in the detection areas that are lit; the judging module is used for judging whether the detection areas are bad areas according to the detection current. The screen of the AMOLED display device is divided into the multiple detection areas which are lit, the detection current of the detection areas is acquired, and whether the detection areas are bad areas is judged according to the detection current; accordingly, brightness uniformity of the AMOLED display device is detected, the detection efficiency is high, detection standards are uniform, and the accuracy is high.

Description

technical field [0001] The present invention relates to the field of AMOLED display devices, in particular to a detection device and method, a repair device and method, and a repair system of an AMOLED display device. Background technique [0002] An AMOLED (Active-matrix organic light emitting diode, active matrix organic light emitting diode) display device has the characteristics of low driving voltage, long life, and high resolution, and is an OLED display device with great potential. [0003] After the AMOLED display device is fabricated, brightness detection needs to be performed to detect the brightness of each area on the screen. The smaller the luminance difference between the various areas on the screen of the AMOLED display device, the better the luminance uniformity. If there are areas with too high or too low brightness on the screen, it is considered that the AMOLED display device has poor mura (screen brightness is not good enough). evenly). [0004] At pres...
