Abstract

The application relates to an LCD electric detection test device, which comprises a base and a gland, the upper surface of the base is provided with an insulating cushion layer for placing an LCD product and a first conductive adhesive tape for abutting against a connecting terminal of the LCD product, the lower surface of the insulating cushion layer is provided with a supporting plate, and the supporting plate is slidably connected to the base. The sliding direction of the supporting plate and the height direction of the base are arranged in the same direction; and a positioning mechanism for positioning the supporting plate is arranged between the supporting plate and the base. The gland is connected to the upper portion of the base in a flip mode, a pressing strip is installed on the side, facing the base, of the gland, a second conductive adhesive tape is bonded to the side, facing the base, of the pressing strip, and when the gland is pressed on the base, the first conductive adhesive tape and the second conductive adhesive tape are attached to each other. The LCD electric detection test device can be suitable for front-mounted and back-mounted LCD products at the same time, the possibility of tilting of the LCD products during electric detection test is reduced, and then the compatibility of the LCD products and the accuracy of electric detection test results are improved.

Description

technical field [0001] The present application relates to the technical field of LCD production, in particular to an LCD electrical testing device. Background technique [0002] With the continuous development of flat panel display technology, LCD has been widely used in various in electronic products. LCD products need to undergo various tests before packaging to detect the production quality of LCD products. [0003] LCD electrical testing refers to the process of testing whether LCD products can display normally by applying voltage to the connection terminals of LCD products; LCD electrical testing is generally carried out with the help of test fixtures. The test fixture includes a base and a pressure plate. The upper surface of the base is provided with an insulating pad for placing LCD products and a first conductive strip for abutting against the connection terminals of the LCD products; the lower surface of the pressure plate is provided with a second The conductiv...
