Abstract

The invention relates to a liquid crystal panel using short-circuit rod detection, in particular to a liquid crystal display panel with short-circuit rods sharing array detection and panel detection. The liquid crystal display panel comprises a panel area, multiple short-circuit rods, multiple panel testing pads and multiple array testing pads. The panel area comprises multiple scanning lines and multiple data lines. The multiple short-circuit rods are arranged in the panel area. The multiple scanning lines and the multiple data lines are electrically connected to the short-circuit rods corresponding to the multiple short-circuit rods by a switching circuit. The multiple panel testing pads are arranged in the panel area. The multiple panel testing pads are respectively electrically connected to the multiple short-circuit rods. The multiple array testing pads are arranged outside the panel area. The multiple array testing pads are electrically connected to the panel testing pads corresponding to the multiple panel testing pads. The liquid crystal display panel has a compact structure and good usage effect.

Description

technical field [0001] The invention relates to a liquid crystal display panel using a short-circuit bar for detection, in particular to a liquid crystal display panel with a shared short-circuit bar for array detection and panel detection. Background technique [0002] Please refer to figure 1 , figure 1 Schematic diagram of test pads for array testing of prior art liquid crystal display panels. The manufacture of the liquid crystal display panel 100 includes an array process, a panel process, and a module process, and tests are performed after each process to eliminate defective products. The array detection includes a full contact detection and a shorting bar detection, and the test pad 130 for the shorting bar detection is disposed outside the panel area 110 of the liquid crystal display panel 100 . In the full-contact detection, each scanning line and each data line are electrically connected to a test pad 120 respectively, and then each test pad 120 is contacted wit...
