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 course of the invention that:

[0027] Taking the LCD display module (LCM, LiquidCrystalDisplayModule) as an example, when the existing LCM can withstand the temperature and ensure the product quality, the normal temperature is 80 degrees Celsius; and the touch screen (TP, TouchPanel) is currently unable to withstand too high a temperature. But the silicone injection molding temperature currently used is generally 180°C....

Abstract

The invention provides an injection molding method of liquid silicone rubber and an electronic device with display screen. The method comprises the following steps: coating mould injection molding Overmolding glue on a product to be treated by injection molding; after curing molding of the glue, carrying out low temperature injection molding with liquid silicone rubber for the product to be treated by injection molding, wherein the low temperature is 25-80 DEG C. The electronic device with display screen comprises a device housing and a display module, the display module comprises a glass cover plate and a display screen, the display module is treated by low temperature injection molding with liquid silicone rubber, wherein the display screen and the glass cover plate are bonded, and the width of the glass cover plate is less than the width of the display screen; the edge of the display screen is fixed to the device housing. The width of the glass cover plate is less than the width of the display screen, the edge of the display screen is fixed by the device housing, and shielding regions do not need to be printed at the two sides of the glass cover plate; Low temperature injection molding with liquid silicone rubber is carried out for the electronic device at a low temperature environment, so that burning-out of the electronic device is prevented, and adhesion strength between the silicone rubber and the electronic device parts is guaranteed.

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...
