With the continuous advancement of LCD module and backlight technology, flat-panel TVs have gradually developed from CCFF (Cold Cathode Fluorescent Lamp) backlights to LED backlights. The thickness of the whole machine is also greatly reduced from the original 100mm at every turn. All-in-one computers have gradually become mainstream. The whole machine manufacturers only purchase the O/C (Open Cell) inside the module, and integrate the module and the whole machine into the integrated design and manufacturing (the face frame and the front iron frame of the module are combined into one). Not only has the cost reduced, but the thickness has also been reduced accordingly. I’d like to expand on the acrylic guide plate to help you understand why the glass light guide plate is excellent enough to be used in LCD screen.
Here is the list of the article:
What’s the working principle of light guide plate?
What’s the benefits of glass light guide plate in LCD screens?
Which TV models can the glass light guide plate be used in?
The light guide plate uses optical grade acrylic/PC sheet, and then uses high-tech materials with extremely high reflectivity and non-light absorption, and UV screen printing technology is used to print the light guide dots on the bottom surface of the optical grade acrylic sheet. The optical grade acrylic sheet is used to absorb the light emitted from the lamp and stays on the surface of the optical grade acrylic sheet. When the light hits each light guide, the reflected light will diffuse in all angles, and then destroy the reflection condition and exit from the front of the light guide plate. The light guide plate can emit light evenly through a variety of dense and different light guide points.
When the plastic light guide plate is used in the application of ultra-large size and ultra-thin LCD TV, its poor system strength and large thermal deformation are the biggest shortcomings. At the same time, the plastic thermal expansion coefficient is large, and the size is greatly affected by the environmental temperature. The structure requires a large safety gap, which is not conducive to narrow Border design. Optical grade glass light guide plate has good light transmittance and good strength, which can solve some of the application deficiencies of plastic light guide plate
Comprehensive advantages and disadvantages of glass light guide plate, glass light guide plate is suitable for some applications of high strength, narrow frame and ultra-thin models.
(1) Ultra-thin LCD TV: Reduce the thickness of the light guide plate, and use its own strength to enhance the strength of the system.
(2) Large LCD TV: Reduce the side safety gap, which is conducive to the narrow frame design, and uses its own strength to enhance the system strength.
(3) Ultra-thin prototype: Through optical glue bonding technology: the glass light guide plate is bonded with two or more materials such as optical film, reflector, back plate, etc., to further reduce the structure and assembly space and thickness to achieve the ultimate Ultra-thin, ultra-narrow display effect.
