Problems solved by technology
However, in the existing scribing process, the method for judging the front and back of the liquid crystal display requires very skilled operators or technicians to judge with human eyes, and it must be judged for each piece
This poses a great challenge to the requirements of the operator and the fatigue work. A little carelessness will lead to misreading the front and back, scribing errors, and resulting in bad waste.
What's more, it will cause a huge waste of material cost and labor cost

Embodiment
[0029] A liquid crystal display panel with a scratch-proof design, such as Figure 1-4 As shown in the figure, the liquid crystal display device unit and the scribing foolproof symbols are arranged in a regular order. The liquid crystal display device unit includes a substrate 101, and a common electrode 201 and a segment electrode 202 are regularly distributed on the substrate 101. The scribing The foolproof symbols are distributed on the four top corners of the common electrode 201 and the segment electrode surface 202, which are respectively the top angle A, the top angle B, the top angle C and the top angle D. , bottom, left and right edge 0.05-0.1mm. The scribing foolproof symbol is a nested combination of a symbol and a letter, and the directionality of the letter is used as a foolproof distinction, wherein the symbol is an equilateral right triangle or a square, and the height and width are both 1mm, so The height and width of the letters mentioned above are both 0.6mm...

Abstract
The invention discloses a method for operating a liquid crystal display panel with scribing and foolproof symbols. The common electrodes and the segment electrodes on the substrate are respectively arranged in a row, a column or a whole surface, and each substrate is provided with a corresponding dicing foolproof symbol. By adopting the fool-proof design of the present invention, quick selection of front and back sides and precise alignment of the liquid crystal display can be realized, which is safe and fool-proof, improves the production efficiency, the accuracy rate and saves the cost. The method can be used in manual and automatic visual alignment planning. piece.
Description
technical field [0001] The invention particularly relates to a method for operating a liquid crystal display panel with a scribing foolproof symbol. Background technique [0002] With the development of liquid crystal display technology, the manufacturing process of liquid crystal display devices is becoming more and more mature, and excellent process methods are the key to ensuring the production quality of liquid crystal devices. The dicing process of the liquid crystal display requires that the liquid crystal display be cut into liquid crystal displays with accurate dimensions and correct front and back sides. However, in the existing dicing process, the method for judging the front and back of the liquid crystal display requires very skilled operators or technicians to judge by human eyes, and must judge each piece. This poses a great challenge to the requirements of operators and fatigue operations. A little carelessness will lead to misreading of the front and back, d...
