Abstract

The invention discloses a method for sealing a signal transfer belt of a liquid crystal screen. The method for sealing a signal transfer belt of a liquid crystal screen includes: step 1, connecting the FPC and the signal transfer belt through a heterosquare conductive adhesive film by hot pressing; Apply sealant to the hot-pressed position of the FPC and the signal transfer belt, and paste anti-static tape; step 3, after the sealant is cured, apply the sealant around the FPC and the signal transfer belt, and stick it again Cover with anti-static tape. The liquid crystal screen signal transfer belt sealing method solves the problems of blurred screen, black screen, white screen and the like that occur due to comprehensive environmental stress.

Description

technical field [0001] The invention relates to a sealing method for a liquid crystal screen signal transition tape. Background technique [0002] The application requirements of liquid crystal displays on aircraft are the highest. Due to the influence of outdoor ambient light, in order to meet strong light visibility, the brightness requirements of liquid crystal displays are relatively high (usually greater than 800cd / m2), while the brightness of civilian displays is usually designed around 400cd / m2 . LCD screen is a passive luminescent display medium, which mainly realizes the high-brightness display of LCD by increasing the brightness of the backlight source. Therefore, the design of the backlight is the key factor to realize the high-brightness display of the liquid crystal display. [0003] The backlight is divided into bottom backlight and side backlight according to the position in the display. The two backlights have their own advantages and disadvantages. The bot...
