Abstract

The invention discloses an AMOLED (Active-Matrix Organic Light Emitting Diode) displayer, a testing component of the displayer and a defect testing method of the displayer. The testing component comprises at least one odd switch, at least one even switch, a first switch circuit, a second switch circuit, and at least one signal source circuit, wherein the at least one odd switch is electrically connected with odd data lines of multiple data lines respectively, the at least one even switch is electrically connected with even data lines of multiple data lines respectively, the first switch circuit is electrically connected with the at least one odd switch and used for transmitting and controlling control signals for connecting and disconnecting the at least one odd switch, the second switch circuit is electrically connected with the at least one even switch and used for transmitting and controlling control signals for connecting and disconnecting the at least one even switch, and the at least one signal source circuit is used for receiving signals from a signal source respectively; each one of the at least one odd switch and the at least one even switch is electrically connected with one of the at lest one signal source circuit, so that signals are transmitted to the corresponding data line.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an AMOLED display, a testing component thereof and a defect testing method thereof. Background technique [0002] Organic light-emitting diodes (OLEDs) have aroused widespread interest due to the advantages of low cost, low power consumption, high brightness, self-illumination, full color, wide viewing angle, and easy fabrication on flexible substrates. In organic light emitting diode displays, AMOLED (Active Matrix / Organic Light Emitting Diode, active matrix organic light emitting diode panel) products use thin film field effect transistors (TFT, hereinafter referred to as transistors) to form pixel circuits to realize OLED screen display. [0003] In the current AMOLED product design, the pixel circuit in the AA area (Active Area, effective display area) adopts the structure of nTmC (n≥4, m≥1, m and n are both positive integers), for example, generally adopts 4T1C / 4T2C Circui...

AI Technical Summary

Problems solved by technology

like figure 2 As shown, when a short circuit occurs between two data lines, or a short circuit occurs between the ITO electrodes on both sides of a data line, the test signal cannot be effectively detected, which is not conducive to the detection of short circuit defects.
