Description

technical field [0001] The invention relates to a polarizer attaching technology, in particular to a polarizer attaching method and device, and belongs to the field of liquid crystal display manufacturing. Background technique [0002] With the development of display technology, thin film transistor liquid crystal display (hereinafter referred to as: TFT-LCD) has gradually become the mainstream of the market because of its superior performance such as high quality, low power consumption, and no radiation. In the TFT-LCD structure, the polarizer is an important component, and its function is to realize the polarization and analysis of natural light. In the TFT-LCD manufacturing process, the attachment of polarizers has become an important process. [0003] figure 1 It is a structural schematic diagram of a polarizer attaching device in the prior art, such as figure 1 As shown, the device includes a horizontal substrate 11 and an adsorption substrate 12. When attaching a po...

AI Technical Summary

Problems solved by technology

[0004] There is a certain contact pressure between the horizontal substrate 11 and the adsorption substrate 12 of the above-mentioned polarizer attaching device. When the horizontal substrate 11 moves horizontally, the stability of the pressure between the two substrates is an important parameter. In the actual process, The problem of non-uniform attachment due to pressure instability between the two substrates is often present, affecting the performance of the panel

Since the horizontal substrate 11 moves in one direction (the negative direction of the X-axis), there are differences in the stress of the attached polarizer on the panel along the X-axis and the Y-axis, which may easily cause the panel to bend in a certain direction. At the same time, in the heating environment, the shrinkage difference of the polarizer is more obvious
