Abstract: A film-applying device and method for 3D glass with two opposite curved edges. The film-applying device comprises: an upper base for fixing a film; a lower base for fixing the 3D glass; a roller structure for rotating a rotary cylinder of the upper base; and a lifting cylinder for moving the upper base, the rotary cylinder, and the roller structure up and down and making the roller structure apply a pressure to press-fit the 3D glass and the film. The roller structure comprises a lower roller and an upper press roller; the rotary cylinder is used for rotating the upper base to change or fix the relative position of the upper base and the roller structure. The device has a simplified structure. The device and method are suitable for applying a film to 3D glass with two opposite curved edges due to convenient operations, high film-applying precision and efficiency.

Abstract: A forming method for curved glass has been provided. The method comprises: placing a flat glass plate in a pattern die, and placing the pattern die in a forming apparatus; and subjecting the pattern die successively to staged heating, staged forming and staged cooling, so as to obtain the curved glass, wherein the staged heating is performed over stages which are different from each other in temperature, the staged forming is performed over stages which are different from each other in temperature, and during at least one of the stages, a varying pressure which varies from low pressure to high pressure is applied to the pattern die, the staged cooling is performed by cooling the glass plate in the pattern die over stages which are different from each other in temperature. The glass product could be used as front and rear covers of electronic products including notebook computers, mobile phones, tablet computers and smart watches.

Abstract: The present disclosure provides a UV film sensor, a preparation method therefor, and a corresponding touch screen. The UV film sensor comprises a film substrate (A) containing a printing surface (a) and an attaching surface (b), and a UV adhesive layer (1), an electroplated color developing particle layer (2), an ink layer (3), a hardened layer (4), an index matching layer (5) and a transparent conducting layer (6) for constructing a touch function structure are sequentially formed on the printing surface of the film substrate from one side close to the film substrate to the other side away from the film substrate. The touch screen is obtained after adhering a cover glass to the attaching surface of the film substrate in the UV film sensor via an optical grade transparent double-sided adhesive. The obtained touch screen only contains one layer of substrate. The touch screen can be thinner as a whole.

Abstract: A method for preparing a sapphire lens includes the following steps: sequentially forming an ink layer and a coating film layer on one surface of a large polymeric membrane; laser-cutting the obtained large polymeric membrane to form two or more small polymeric membranes that are as thick as the large polymeric membrane; laminating the surface of the small polymeric membrane that does not contain the ink layer and the coating film layer to one surface of a sapphire sheet, such that an adhesive layer is formed between the small polymeric membranes and the sapphire sheet, wherein the sapphire sheet has a thickness of 0.3 to 1.5 mm, and the polymeric membrane has a thickness of 0.02 to 0.2 mm; and pressing the obtained sheet material to remove bubbles, thereby obtaining a sapphire lens.

Abstract: A touch panel and a preparation method therefor, which relate to the technical field of electronic device preparation. The method for preparing a touch panel comprises: firstly, preparing a BM frame layer (1), and then sequentially preparing an ITO1 layer (2), an OC1 layer (3) and an ITO2 layer (4a, 4b) in the BM frame layer (1); then, preparing a window frame layer (5) outside the BM frame layer (1) by means of a printing process; and finally, preparing a designated metal wiring layer (6a, 6b) and an OC2 layer (7). The touch panel and the preparation method therefor solve the problem that a white window frame in the current industry is yellowed easily. Compared with a yellow light lithography for preparing the window frame, the printing process for preparing the window frame is simpler in production process, higher in defect-free rate and lower in corresponding cost, and can reduce pollution from discharge of wastewater and waste gas generated by the chemical solution to the environment.
