Liquid crystal display polarizer production stretching procedure processing technology

Abstract

The invention relates to a liquid crystal display polarizer production stretching procedure processing technology. The technology uses a liquid crystal display polarizer production stretching procedure processing device, wherein the liquid crystal display polarizer production stretching procedure processing device comprises a stretching groove, a color supplementing groove, a stretching device anda color supplementing device, wherein the stretching groove is located on the left side of the color supplementing groove, the stretching device is installed on the stretching groove, and the color supplementing device is mounted on the color supplementing groove. According to the liquid crystal display polarizer production stretching procedure processing technology, PVA film stretching and colorsupplementing treatment are carried out by adopting the design concept of intermittent joint operation, the intermittent working pace of the stretching device and the intermittent working pace of thecolor supplementing device are consistent and controlled mechanically, the working intensity of workers is relieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display modules, in particular to a process for the production and stretching process of a liquid crystal display polarizer. Background technique [0002] The full name of the polarizer is a polarizer, which can control the polarization direction of a specific beam. When natural light passes through the polarizer, the light whose vibration direction is perpendicular to the transmission axis of the polarizer will be absorbed, and only the vibration direction and the transmission axis of the polarizer will be absorbed by the transmitted light. For polarized light parallel to the axis, polarized lenses are globally recognized as the most suitable lenses for driving. When the light is reflected from the surface of the object, it has been partially polarized to produce glare. Blurring, causing eye fatigue and discomfort. Polarizers are made according to the principle of polarization of light. Th...

Problems solved by technology

[0003] 1. In the process of stretching the PVA film, the PVA film is in a loose state as a whole, and the unstretched part is prone to move and shrink inward, thus weakening the stretching effect of the stretching device on the PVA film, and the stretching of the PVA film The degree is low, and at the same time, the stretching device stretches the PVA film instantly with a large stretching force, which easily causes the PVA film to be stretched too much;

[0004] 2. After the PVA film is supplemented with color, there will be excess floating color on the surface of the PVA film, which will easily cause uneven color on the PVA film without scraping off, and will also have a certain impact on the subsequent bonding of the PVA film and the TAC film. At the same time, the two steps of color replenishment and floating color removal are separated and performed separately, which easily complicates the operation steps
