Method for polaroids debubbling in LCD (liquid crystal display) production

Abstract

A method for polaroids debubbling in LCD (liquid crystal display) production includes steps: 1) putting an LCD with the polaroids between pressure bearing plates, and tightening the pressure bearing plates by the aid of bolts, wherein the pressure bearing plates are steel plates wrapped with linen cloth; 2) putting the LCD at the step 1) along with the pressure bearing plates into a debubbling machine; 3) heating the interior of the debubbling machine to 60-70 DEG C, and keeping for 10-20min; 4) feeding compressed air into the debubbling machine to adjust the internal pressure of the debubbling machine to 0.5-0.8MPa, and keeping for 8-15min. By adoption of the method for polaroids debubbling in LCD production, bubbles generated in surface mounting of the polaroids can be eliminated effectively.

Description

technical field [0001] The invention relates to LCD production equipment, in particular to a method for defoaming polarizers in LCD production. Background technique [0002] Polarizer bubbles refer to the residual gas between the polarizer and the surface of the liquid crystal glass cell due to factors such as the attachment environment, attachment process, and attachment method when the polarizer is attached to the surface of the liquid crystal glass cell. When using the attachment device to attach the polarizer to the surface of the liquid crystal glass cell, since there is a large amount of gas between the two, it is difficult to drive out all the gas from the two simply by squeezing when attaching, and The attachment device and some human factors will also affect the attachment effect to a certain extent. When the polarizer is attached to the LCD glass box, a certain number of tiny bubbles will inevitably remain, some of which are even difficult to detect with the naked ...

Problems solved by technology

When using the attachment device to attach the polarizer to the surface of the liquid crystal glass cell, since there is a large amount of gas between the two, it is difficult to drive out all the gas from the two simply by squeezing when attaching, and The attachment device and some human factors will also affect the attachment effect to a certain extent. When the polarizer is attached to the LCD glass box, a certain number of tiny bubbles will inevitably remain, some of which are even difficult to detect with the naked eye. When the light deflected into one direction by the lower polarizer passes through these tiny bubbles, this part of the light will deviate from the original direction due to refraction, which will cause the color of this part to be inconsistent with the color of other parts, which will affect the display effect of the display.
