Embodiment approach

[0031] In the first type, there are two film-shaped constant-temperature liquid circulation pipelines 5, which are respectively attached to the two opposite sides of the base 2, and the two film-shaped constant-temperature liquid circulation pipelines 5 are connected in series or in parallel connected to the liquid supply system. Wherein, in this embodiment, the constant temperature effect of the parallel-connected thin-film constant-temperature liquid circulation pipelines 5 is due to the series-connected thin-film constant-temperature liquid circulation pipelines 5 .

[0032] The second type, such as Figure 5 As shown, there are four film-shaped constant-temperature liquid circulation pipelines 5, which are respectively attached to the four sides of the base 2, and the four film-shaped constant-temperature liquid circulation pipelines 5 are connected in parallel to the supply liquid system, and,

[0033] The joints of any two sides are respectively set as the liquid inlet...

Abstract

The invention relates to a measuring machine for the height of an optical spacer. The measuring machine comprises a base for placing an item to be measured, a measuring device, and a film-like constant temperature liquid circulation line, wherein the film-like constant temperature liquid circulation line is attached to the side of the base. According to the measuring machine for height of opticalspacer, temperature of the base is regulated by setting the film-like constant temperature liquid circulation line to prevent the internal temperature of the equipment from being too high. Therefore,the fluctuation and influence of the ambient temperature on the measurement of the PS size is eliminated, and the accuracy of the data measurement is improved. The accurately measured PS size is provided for bonding process of the TFT and CF, Cell Gap(box thickness) uniformity of liquid crystal distribution is ensured, and the liquid crystal display effect is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, and more particularly, to an optical spacer height measuring machine. Background technique [0002] As a mainstream product in the flat panel display market, TFT-LCD panels change the arrangement of liquid crystal materials by controlling the electric field between the upper and lower substrates of TFT (Thin Film Transistor) and CF (Color Filter), so as to achieve the expected display effect. [0003] like figure 1 As shown, the PS (Photo Spacer) process is an important process in the production of CF substrates. Through the adjustment of process parameters, PS spacers with different column heights and sizes can be obtained to maintain the uniform flatness of the TFT substrate and CF substrate. , and Cell Gap (box thickness) that provides liquid crystal distribution. When TFT and CF are laminated (in the same pressure state), different sizes of PS have different compression amou...
