Problems solved by technology

[0005] 1. Every time a product with a different resolution is changed, it takes 1 to 2 hours to replace and confirm the fixture, resulting in a decrease in production capacity;
[0006] 2. For each product with different resolutions, 4 to 8 fixtures need to be prepared, and the number of fixtures will be large, resulting in an increase in cost;
[0007] 3. It takes 1 to 2 months to make a fixture suitable for one resolution, and the new product stage may not be able to detect in time to confirm the yield status

Abstract

A display device includes: a first substrate, a second substrate and a display molecule layer disposed between said first substrate and said second substrate; a plurality of thin film transistors disposed on the display area of said first substrate; a plurality of gate lines respectively electrically connected to the control terminal of said thin film transistor; a plurality of data terminals located on the peripheral area and respectively electrically connected to the first terminal of said thin film transistor; and a plurality of virtual terminals located in the peripheral area and respectively electrically insulated from each of said thin film transistors; wherein said data terminals and said virtual terminals are staggered along a first direction.

Description

technical field [0001] The invention relates to the field of display design, in particular to the design of a test pad (Array Test Pad) in the display and a display device using the test pad. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD, Thin Film Transistor Liquid Crystal Display) is a common display, TFT-LCD is an active matrix liquid crystal display, and the liquid crystal pixels on the TFT-LCD are driven by thin film transistors, that is, through Active switches are used to achieve independent and precise control of each pixel, so that high-speed, high-brightness, high-contrast display screen information can be achieved to achieve fine display effects. [0003] The structure of TFT-LCD mainly includes CF substrate, TFT substrate and liquid crystal material. In the production process of the TFT-LCD panel, it is an important step to check the electrical characteristics of the TFT substrate. In the prior art, an Array Tester (Array Te...
