Description

Technical Field

[0001] The utility model relates to the technical field of display screen lamination, in particular to a lamination device for producing an anti-deviated liquid crystal display screen. Background Art

[0002] Liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers. LCD displays use two polarized materials with a liquid crystal solution between them. When an electric current is passed through the liquid, the crystals rearrange themselves so that light cannot pass through them. Therefore, each crystal acts like a shutter, which can either allow light to pass through or block light.

[0003] However, in the production process of LCD screens, the precise bonding of the LCD panel and the backlight module is a key step to ensure product quality. In actual operation, the existing bonding device has a problem of slippage due to the small friction between the work surface and the screen, since the screen is directly placed on the work surface. This leads to poor display effect and affects the final display effect of the product.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-drifting laminating device for LCD production is proposed. Utility Model Content
