[0058] When the first storage capacitor C st1 with the first liquid crystal capacitor C lc1 The ratio of is not equal to the second storage capacitor C st2 with the second liquid crystal capacitor C lc2 When the ratio is higher, the method for manufacturing a liquid crystal panel further includes the following steps.

[0059] First, according to V 1 =C st1 / (C st1 +C lc1 )*V curing1 Relational expression, to generate the voltage V of the first pixel electrode 311 to be 1 When it is equal to a coupling voltage V, the first curing voltage V that needs to be applied to the second common electrode 324 curing1 .

[0060] Next, according to V 2 =C st2 / (C st2 +C lc2 )*V curing2 Relational expression, to generate the voltage V of the second pixel electrode 321 to be 2 When equal to the coupling voltage V, the second curing voltage V required to be applied to the third common electrode 334 curing2 .

[0061] That is to say, during the process of curing the alignment o...

[0066] Considering the manufacturing process, it is desired to use the same curing voltage (V curing1 =V curing2 ), and the voltage reaching the two pixel electrodes is the same (V 1 =V 2 ) purpose, it is necessary to adjust the first liquid crystal capacitor C lc1 , the first storage capacitor C st1 , the second liquid crystal capacitor C lc2 and the second storage capacitor C st2 The proportional relationship between them.

[0067] It can be known from the aforementioned relational formula that the voltages at the two pixel electrodes are the same (V 1 =V 2 ) and the two curing voltages are the same (V curing1 =V curing2 ), the first storage capacitor C st1 with the first liquid crystal capacitor C lc1 ratio (C st1 / C lc1 ) must be equal to the second storage capacitor C st2 with the second liquid crystal capacitor C lc2 ratio (C st2 / C lc2 ), which satisfies C st1 / C lc1 =C st2 / C lc2 Relationship.

[0068] That is, when the first storage capacitor C ...

Abstract

A method for preparing liquid crystal face-plate applies PSA technique to change specific value of each liquid crystal capacity to storage capacity in unit pixel for making voltage on each pixel electrode in unit pixel be approximately equal in order to let predip angle of liquid crystal molecule be more identical.

Description

technical field [0001] The invention relates to a method for making a liquid crystal panel, in particular to a method for making a liquid crystal panel by utilizing polymer stable alignment technology. Background technique [0002] With the advancement of display technology, compared with traditional CRT displays, liquid crystal display (TFT-LCD) has become the main force in the display market due to its advantages of lightness, thinness, low radiation, and small size without occupying space. At the same time, it is widely used in various electronic products such as calculators, personal digital assistants (PDA), notebook computers, digital cameras, and mobile phones. [0003] In response to the rapid development of liquid crystal display products, the competition among liquid crystal panel manufacturers is increasing day by day. The industry's active investment in research and development and the adoption of more advanced production equipment have led to a continuous reduc...
