Problems solved by technology

When it is required to display more content, such as a vertically aligned liquid crystal display with a duty ratio of 1 / 16duti or above, the products made in the prior art will have reduced contrast, obvious crossover effects, and narrow viewing angle range, resulting in poor display. Defects such as blind spots, the LCD monitor cannot display graphics normally

Abstract

A method for manufacturing a high-duty cycle vertical orientation liquid crystal display device comprises a preceding step of forming patterns on glass substrates, a middle step of coating the substrates with an orientation liquid and carrying out orientated friction, and a final step of manufacturing a glass box, injecting liquid crystals, and manufacturing a liquid crystal display screen, wherein in the middle step, the glass substrate is coated with the orientation liquid; the glass substrate coated with the orientation liquid is baked and cured in a low-temperature environment of 60-120 DEG C; and orientated friction is performed on one of a pair of glass substrates for forming the glass box. The vertical orientation liquid crystal display device manufactured using the method of the invention may achieve high-channel number digital driving, namely, the duty cycle of the liquid crystal display may be 1-1 / 128 duty. The method for manufacturing the high-duty cycle vertical orientation liquid crystal display device has the advantages of high contrast ratio, full-visual angle without dead zone, high response speed, high definition, and the like.

Description

Technical field [0001] The invention relates to the manufacturing technology of liquid crystal displays, in particular to the manufacturing technology of the directional rubbing process of high duty ratio vertical alignment to the liquid crystal display. Background technique [0002] The vertical alignment liquid crystal display (VA-LCD) has the characteristics of high contrast and wide viewing angle, which is unique in the field of liquid crystal display. The product has a wide range of applications, such as automotive products, home appliances, smart wearables and other applications. The existing (VA-LCD) product is a low duty cycle (1 / 8 DUTY and below) liquid crystal display with a low number of driving channels. In the low duty cycle, such as 1 / 2, 1 / 4 DUTY use will reflect the characteristics of high contrast and wide viewing angle, so more field-type liquid crystal displays are currently applicable. The existing vertical alignment liquid crystal display (VA-LCD) manufactur...
