Method for preparing thin type press key panel

Abstract

A method for manufacturing a thinning keystroke panel including a smooth surface, a misty surface or a grain layer is disclosed, comprising the steps of: at first, manufacturing a first module whose inside bottom surface is coarse surface, smooth surface or grain surface, dropping colloid into the first module and covering a first carrier on the surface of the colloid, using idler wheels to roll and press the first carrier and the colloid so as to be flat within the module; then irradiating with ultraviolet light in order that the colloid is hardened to form a keystroke layer attached to the first carrier, afterwards, on the carrier, sequentially film-forming a bottom colour layer, a functional colour layer and a font colour layer as the background of the keystroke panel; subsequently, manufacturing a second carrier, printing a reflecting layer on the surface of the second carrier, disposing the second carrier and the silicon gel into the second module to be hot-pressed to form an elastic elasticity layer, then bonding the elasticity layer with the keystroke layer to complete the manufacturing of the keystroke panel.

Description

Technical field [0001] The invention relates to a key structure, in particular to a manufacturing method of a thin key structure. Background technique [0002] When purchasing a mobile phone, general consumers, in addition to considering the functions of the mobile phone, the most important thing is whether the appearance and shape of the mobile phone are novel enough and whether the size is small enough. Therefore, some mobile phones print colored patterns on the casing or buttons, or directly produce three-dimensional patterns on the casing, so as to increase the added value of the product and the consumer's desire to buy. [0003] See Figure 1A , The traditional three-dimensional texture production is to attach a first transparent layer 2a on the substrate 1a, attach a first color layer 3a and a color opening 31a on the first transparent layer 2a, and attach a second color layer 3a on the first color layer 3a. The transparent layer 4a, and the second color layer 5a attached t...

Problems solved by technology

Because this scheme arranges the textured layer 1b between the film layer 2b and the elastic layer 3b, not only the steps or procedures of the production are increased, but also the man-hours are relatively increased. On the other hand, the thickness of the keys is also increased. A less-than-ideal design for the thickness of the buttons
