Description

Technical Field

[0001] The present invention relates to the field of display screens, and in particular to a panel laminating device for producing liquid crystal display screens. Background Art

[0002] Panel lamination for LCD production is a critical step in display manufacturing, involving the precise and secure bonding of the front panel (LCD screen, touchscreen layer, etc.) to the backplane or other components. LCDs are a flat-panel display technology that utilizes the properties of liquid crystal materials to display images by controlling the transmission or blocking of light. The liquid crystal material in a display has controllable optical properties. When voltage is applied, its alignment changes, affecting the polarization of the light passing through it. Polarizers control the on / off switching of light, enabling image display.

[0003] However, traditional panel laminating devices used in LCD production lack an automatic adjustment mechanism and usually adopt manual or semi-automatic positioning and clamping methods. This adjustment is prone to errors, resulting in the display screen not being completely centered or the angle being inaccurate. The applied pressure cannot be automatically and accurately adjusted to the appropriate range, resulting in a lack of pressure monitoring and automatic adjustment system, which can lead to over-tightening or over-loosening during operation.
