Abstract

The invention relates to array substrate detecting equipment. The array substrate detecting equipment comprises a signal input unit and a signal detecting unit, wherein the signal input unit is connected with a plurality of array substrates, and is used for inputting detection signals to the array substrates; the signal detecting unit is used for acquiring electrical waveform signals of pixels in the array substrates and determining whether the pixels on the array substrates are defected or not; an on-off switch is connected between each array substrate and the signal input unit. The array substrate detecting equipment can independently input a detection signal to only one certain array substrate to be detected, so that when the signal detecting unit detects that the pixels in the array substrate are defected, the array substrate detecting equipment can accurately distinguish the array substrate with the defected pixels.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and in particular, to an array substrate detection device. Background technique [0002] In the manufacturing process of Thin Film Transistor Liquid Crystal Display (hereinafter referred to as TFT-LCD), after preparing multiple array substrates on the glass substrate, in order to ensure the quality of the product, it is necessary to use testing equipment to test the array substrates. Pixels in the sensor are detected to avoid defective products in the subsequent production process. [0003] figure 1 It is a schematic diagram of an existing detection of an array substrate. Such as figure 1 As shown, when the array substrate 1 is detected, the signal input unit (not shown in the figure) moves to the top of the array substrate 1 to be detected, and is arranged on the glass substrate 2, and is connected to the data lines and gates of the array substrate 1 respectively. A pl...
