Embodiment Construction

[0023] In order to make those skilled in the art more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 and figure 2 As shown, in one embodiment of the present invention, the finished liquid crystal diaphragm includes a diaphragm body 100, and the diaphragm body 100 includes an upper film base material 10, an upper film conductive layer, and an upper film conductive layer arranged sequentially from top to bottom. 20. The liquid crystal layer 30, the lower film conductive layer 40 and the lower film substrate 50. On the front of the diaphragm body 100, an upper film substrate is formed at a predetermined distance from the peripheral edge line 70 of the diaphragm body 100. 10 and the half-cut line 60 cut off by the upper film conductive layer 20. The upper conductive layer 20 and the lower con...

Abstract

The invention discloses a liquid crystal diaphragm cutting method and a finished liquid crystal diaphragm. The liquid crystal diaphragm cutting method comprises the steps that S1, a liquid crystal diaphragm is cut into multiple finished diaphragms of preset sizes; S2, cutting is carried out to form semi-cutoff lines on the portions, with a preset distance, from the edges of the peripheries of thefinished diaphragms, and the semi-cutoff lines cut off upper film conductive layers on the finished diaphragms. The liquid crystal diaphragm cutting method has the advantages that after the liquid crystal diaphragm is cut into the finished diaphragms of the preset sizes, re-cutting is carried out to form semi-cutoff lines on the portions, with a preset distance, from the edges of the peripheries of the finished diaphragms, the semi-cutoff lines cut off the upper film conductive layers on the finished diaphragms so that the voltage of the upper film conductive layers cannot reach the edge of the liquid crystal diaphragm, and the upper film conductive layers and lower film conductive layers do not short-circuit; the semi-cutoff lines formed by re-cutting the finished diaphragms can block theflow of liquid crystal, so that the liquid crystal around the diaphragm can be fixed, thereby not causing cracking of the diaphragm.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for cutting a liquid crystal film and a finished liquid crystal film. Background technique [0002] With the development of liquid crystal writing board (light energy blackboard) technology, the competition in the liquid crystal writing board industry is becoming more and more fierce, and the cost requirements of products are also getting higher and higher. How to improve product quality and reduce product cost has become an urgent problem for manufacturers. problem. For a long time, the main problem that has plagued the industry of liquid crystal writing boards (light energy blackboards) is that the defective rate of liquid crystal diaphragms remains high, mainly manifested in the fact that the diaphragms are easy to burst and short circuit after cutting. The existing traditional process method is to use artificial Use glue to reduce bursting and use a b...
