Description
Technical Field
The invention relates to the technical field of liquid crystal panels, in particular to a liquid crystal panel with an ultra-narrow frame side coding structure and a side coding method thereof.
Background
The identification code (Glass ID) on the TFT-LCD liquid crystal panel comprises information such as product type, material, history and the like. The identification code (Glass ID) is generally composed of english letters, numbers, and two-dimensional codes. The laser code printing is generated in the production process in a laser code printing mode, and is an important carrier for producing digitalization and intellectualization. Referring to fig. 1, the identification code (Glass ID)80 is generally designed on the peripheral border of the Active Area (AA). Considering the precision of laser coding process, the width of the identification code (Glass ID) is about 200-1000 um. With the rise of products such as ultra-narrow frames, frameless frames and spliced screens, new challenges are brought to product processes by the design of increasingly narrow frames.
The bezel width is reduced, requiring a simultaneous reduction in the identification code (Glass ID) width. For an ultra Narrow bezel (ENB) product with a bezel width of less than 0.9mm, there are more stringent requirements for coding accuracy and recognition accuracy.
Referring to fig. 2, an identification code (Glass ID)80 of the ENB product is implemented by reserving a wider operation area (Dummy area) at the periphery of the bezel. And setting a frame on the Dummy area. By cutting, the Dummy area is cut off to realize a narrow bezel. Then, the coding is realized by pasting the character identification code 90 on an effective display Area (AA), and the identification code is torn off after the display finished product is assembled so as to avoid influencing the display.
