Abstract

The invention discloses a screen lens structure of a mobile terminal. The screen lens structure comprises a 2.5D arc-face glass optical lens and a transparent material. The 2.5D arc-face glass optical lens is used as a screen lens. The transparent material extends to the lower end face of the peripheral arc edge of the 2.5D arc-face glass optical lens and is used for forming the screen lens structure achieving a 3D function with the 2.5D arc-face glass optical lens. The transparent material has the function of the glass optical lens. The face radian of the transparent material is identical to that of the peripheral arc face of the 2.5D arc-face glass optical lens, the connecting faces of the transparent material and the 2.5D arc-face glass optical lens are matched, the lower end face of the transparent material is matched with the screen edge of the mobile terminal, and the 2.5D arc-face glass optical lens and the transparent material are combined and fixed to form an integrated structure with a smooth surface. According to the screen lens structure of the mobile terminal, the machining difficulty in the prior art is reduced, the appearance of the screen of the mobile terminal can achieve a stereoscopic effect, the manufacturing mode is low in cost, and the needs of consumers for pursuing fashion-orientation and diversification can be met.

Description

Technical field [0001] The invention relates to the field of mobile phone screens, in particular to a screen lens structure of a mobile terminal and a manufacturing method thereof. Background technique [0002] With the development of screen technology, consumers are increasingly dissatisfied with the flat screen effects of mobile terminals. Single curved screens, 2.5D curved screens and 3D curved screens are becoming more and more popular. However, the current 3D curved screens are all processed using 3D forming glass technology. The 3D forming glass technology is to place the glass between the arc molds, heat it to 800°C close to the melting edge, and then press it into the arc mold After the glass is bent, it is processed and polished by CNC engraving machine, and then the decorative pattern is thermally transferred for visual effect processing. [0003] At present, the processing yield of 3D formed glass is low, the overall yield rate is less than 50%, and the production canno...
