Problems solved by technology

[0002] The traditional LGP light guide plate is made of acrylic resin or other organic resins. Due to the raw material, the LGP light guide plate has always had shortcomings such as insufficient physical strength, easy deformation due to heat and humidity, and can only be processed by various auxiliary materials and plastic frames. designed to overcome
It is undeniable that such shortcomings have become a constraint to reduce the thickness of LCD TVs and achieve more stylish designs of products
[0003] In addition, curved displays are becoming more and more fashionable at present, so it is necessary to prepare curved light guide plates to adapt to different product terminals. However, in the production process of curved glass light guide plates, due to the high softening temperature of glass, it is necessary to heat the glass before the curved surface Light guide dots can only be printed after forming. Printing dots on a curved glass plate has technical defects such as high production difficulty and poor quality.

Embodiment 1

[0018] A method for designing a PCB impedance plate, comprising the following steps:

[0019] a. Prepare a 4mm ultra-clear glass plate, grind the edges of the ultra-clear glass plate, and polish one side of the ultra-clear glass plate as the light-emitting surface, and the unpolished side as the dot surface;

[0020] b. Wash the polished ultra-clear glass plate with soft water, and dry it with hot air;

[0021] c. On the dot surface of the ultra-clear glass plate, print dots with high-temperature resistant ink according to the designed dots. The diameter of the dots is 100 μm, and the thickness of the ink is 0.5 mm. The high-temperature resistant ink is based on silicone resin It is prepared by adding glass powder, vanadium pentoxide and light guide powder;

[0022] d. Send the ultra-clear glass plate after screen printing into the tempering furnace, temper it at 700°C and shape it according to the set arc surface;

[0023] e. Cooling and cleaning the ultra-clear glass plate...

Embodiment 2

[0025] a. Prepare a 3.5mm ultra-clear glass plate, grind the edges of the ultra-clear glass plate, and polish one side of the ultra-clear glass plate as the light-emitting surface, and the unpolished side as the dot surface;

[0026] b. Wash the polished ultra-clear glass plate with soft water, and dry it with hot air;

[0027] c. On the dot surface of the ultra-clear glass plate, print dots with high-temperature resistant ink according to the designed dots. The diameter of the dots is 110 μm, and the thickness of the ink is 0.8mm. The high-temperature resistant ink is based on silicone resin It is prepared by adding glass powder, vanadium pentoxide and light guide powder;

[0028] d. Send the ultra-clear glass plate after screen printing into the tempering furnace, temper it at 720°C and shape it according to the set arc surface;

[0029] e, cooling and cleaning the ultra-clear glass plate after the curved surface is formed, to obtain a curved glass light guide plate;

Abstract

The invention discloses a bent glass light guide plate preparation method. Light guide screen dots can be printed through high-temperature-resistant printing ink before curved surface formation of plate glass. The method is simple in printing process and high in quality, and can enable a light guide plate to keep good light guide performance after formation; and the technical defect caused by a mode that a curved surface is formed first, and then, the light guide screen dots are printed in the prior art is overcome.
