Problems solved by technology

At present, the welding goggles on the market can basically block all ultraviolet rays, and the infrared transmittance is less than 5%, but at the same time, the visible light transmittance is about 0.1%, so the vision is dark after wearing, which brings extreme difficulties to the welding workers. Big trouble, and directly affect the welding quality

Example Embodiment

[0021] [Example 1]

[0022] In this embodiment, a high-grade LCD welding goggles includes a thickened filter, a first C compensation polarizer, a first LCD liquid crystal cell, a second C compensation polarizer, and a second LCD liquid crystal from top to bottom. Cell and R compensation polarizer; the liquid crystal twist angle of the first and second LCD liquid crystal cells is 70°, and the absorption axis of the first and second C compensation polarizers is clamped with the friction axis in the first and second LCD liquid crystal cells The angles are respectively 1°; the monomer transmittance of the first and second C compensation polarizers and R compensation polarizers are both 42%, and the polarization degree is 99%; the thickened filter is an ultraviolet filter with thickness It is 1mm and the monomer transmittance is 27%.

[0023] The first liquid crystal cell and the second liquid crystal cell are both TN liquid crystal cells.

[0024] The thickness of the liquid crystal la...

Abstract

The invention relates to a pair of high-class LCD welding goggles. The pair of high-class LCD welding goggles sequentially comprises a thickened light filter, a first C compensating polaroid, a first LCD liquid crystal box, a second C compensating polaroid, a second LCD liquid crystal box and an R compensating polaroid from top to bottom. The uniformity, light dispersivity, response speed and viewing angle dependence meet the primary standard of European union (CE) certification. When the pair of high-class LCD welding goggles is used, strong arc light can be blocked in time during welding, the state of clear viewing field can be also rapidly recovered after welding is stopped, and smooth performing of welding work is effectively guaranteed.

Description

technical field [0001] The invention relates to an LCD goggle, in particular to a high-grade LCD welding goggle whose uniformity, light diffusion, response speed, and viewing angle dependence meet the EU CE 1 / 1 / 1 / 1 standard. Background technique [0002] The short-term exposure of the ultraviolet rays generated by electric welding to the eyeball will cause damage to the cornea and conjunctival tissue (28nm light is the most serious), and the strong infrared rays generated can easily cause eye lens turbidity. Welding goggles are used to block infrared and ultraviolet rays. At present, the welding goggles on the market can basically block all ultraviolet rays, and the infrared transmittance is less than 5%, but at the same time, the visible light transmittance is about 0.1%, so the vision is dark after wearing, which brings extreme difficulties to the welding workers. It is a big trouble and directly affects the welding quality. [0003] In addition, the current welding gogg...
