Embodiment Construction
[0015] The liquid crystal display substrate provided by the present invention and its cutting method will be described in detail below with reference to the accompanying drawings.
[0016] refer to figure 2 , a schematic diagram of an embodiment of the liquid crystal display substrate of the present invention. The liquid crystal display substrate includes: a thin film transistor array glass substrate 21 and a color filter glass substrate 22 , an external lead connection terminal area 23 and a black layer 24 .
[0017] The thin film transistor array glass substrate 21 and the color filter glass substrate 22 are bonded by sealant, and can be cut along preset cutting lines to form at least two liquid crystal display panels (only one liquid crystal display panel is shown in the figure). Among them, the coating of the frame sealant can adopt the design method of the coating of the frame sealant under the cutting line (that is, the COS design), that is, the coating of the frame se...

The invention discloses a liquid crystal display substrate and a liquid crystal display substrate cutting device and method. The liquid crystal display substrate comprises a thin film transistor array glass substrate, a colored filter glass substrate, an external lead connector area and a black bottom layer, wherein the thin film transistor array glass substrate and the colored filter glass substrate are bonded through sealing glue, the external lead connector area is arranged on the thin film transistor array glass substrate, and the black bottom layer is arranged under the colored filter glass substrate and extends from a colored filter cutting line on the colored filter glass substrate to the external lead connector area by a preset width. Due to the fact that the black bottom layer extends from the colored filter cutting line on the colored filter glass substrate to the external lead connector area by the preset width and expands by a certain width based on the colored filter cutting line after cutting is finished to automatically detect whether black bottom layer residues exist, whether colored filter glass substrate residues exist in the external lead connector area is detected automatically without manual work, in this way, production efficiency is improved and production cost is reduced while the quality of a liquid crystal display panel is improved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display substrate capable of automatically detecting whether there is any residue after cutting a glass substrate of the liquid crystal display substrate, a liquid crystal display substrate cutting device and a cutting method. Background technique [0002] The liquid crystal display panel (panel) is the most important component of the liquid crystal display (Liquid Crystal Display, LCD). , TFT) array substrate, and a liquid crystal layer (Liquid Crystal Layer) disposed between the two substrates. In the manufacturing process of liquid crystal display panels, in order to improve production efficiency, multiple TFT array substrates are first formed on a larger TFT Glass (TFT glass substrate), and multiple CF substrates are formed on another larger CF Glass (CF glass substrate); then, two larger TFT glass substrates and CF glass substrates are glued ...
