Abstract

The invention discloses a chip testing device of a display and a display with the chip testing device. The device comprises M testing wires, N switch units and a control unit, the testing wires are arranged on N to-be-tested signal lines on a chip in a penetrating manner; when the testing wires face the to-be-tested signal lines of a first film of the chip, the testing wires are arranged on a second film of the chip; when the testing wires face the to-be-tested signal lines on the second film, the testing wires are arranged on the first film; the testing wires are used for receiving signals on at least one to-be-tested signal line; first ends of the N switch units are separately connected with the N to-be-tested signal lines correspondingly; a second end of each switch unit is connected with an optional one of the M testing wires; each switch unit is used for controlling the corresponding to-be-tested signal line to communicate with the corresponding testing wire; and the control unit is used for controlling the N switch units, so that required signals can be measured rapidly and effectively, and accuracy and effectiveness of signal measurement are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display chip testing device and a display with the device. Background technique [0002] Displays such as TFT LCD often have poor wiring and other defects during reliability testing and normal use. In the related art, it is usually necessary to measure the output signal of the driver chip or other wires when performing fault analysis. However, in the related art, there is an insulating layer on the surface of the signal line and there is no test point, so that the required signal cannot be measured, which greatly affects the analytical test of the product. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a chip testing device for a display, which can quickly and effectively measure a required signal without distort...
