Embodiment Construction

[0025] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples. And in the case of no conflict, the embodiments in this description and the features in the embodiments can be combined with each other.

[0026] The inventor noticed during the invention that:

[0027] Taking the LCD display module (LCM, Liquid Crystal Display Module) as an example, when the existing LCM can withstand the temperature and ensure the product quality, the conventional temperature is 80 degrees Celsius; and the touch screen (TP, Touch Panel) is currently also due to the internal There are lines that cannot withstand too high a temperature. But the silicone injection molding tempera...

Abstract

Provided in the present invention are a liquid silicone rubber injection molding method and an electronic device with a display screen. The method comprises: coating the product to be injected with Overmolding glue, injecting a liquid silicone rubber at a low temperature on the product after the glue solidified, the low temperature is from 25℃ to 80℃. The electronic device with a display screen comprises a device housing and a display module, the display module comprises a glass cover plate and a display screen and is molded by injecting the liquid silicone rubber at a low temperature, wherein the display screen is bonded with the glass cover plate, the width of the glass cover plate is less than that of the display screen, and the edge of the display screen is fixed to the device housing. In the present invention, the width of the glass cover plate is less than that of the display screen, and the edge of the display screen is fixed by the device housing, therefore blocked areas are no longer required to be printed on the two sides of the glass cover plate. Injecting the liquid silicone rubber at a low temperature on the electronic device ensures that the electronic device will not be burned out and the binding force between the silicone rubber and the electronic device at a low temperature environment.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a liquid silicone injection molding method and an electronic device with a display screen. Background technique [0002] At present, in the manufacturing process of terminal equipment, attempts have been made to integral injection molding of silica gel and glass. However, since the current injection molding temperature of silicone is usually 180°C, it cannot be used for products that are afraid of high temperatures; in addition, the curing speed of silicone is relatively slow (usually about 10 minutes), which affects productivity, and is particularly easy to fall off, resulting in poor assembly and appearance defects etc. Contents of the invention [0003] The embodiment of the present invention proposes a liquid silicone injection molding method and an electronic device with a display screen, which solves the problem in the prior art that silicone injection molding cannot b...
