Abstract

The invention provides a manufacturing method of a trackpad. The method comprises: step 1, providing a glass substrate; step 2, conducting etching on the surface of the glass substrate with silk print etching ink; and step 3, immersing the etched glass substrate in a glass polishing solution to carry out polishing, thus obtaining the trackpad. The invention also provides the trackpad obtained by the method. Employment of the method disclosed in the invention to manufacture the trackpad can ensure the touchpad certain roughness, improve the touch sense of existing trackpads, and can endow the trackpad with certain light transmittance and guarantee its glossiness. Therefore, the method is conducive to improve the quality of the trackpad, thus further improving the use performance of electronic products.

Description

technical field [0001] The invention relates to the field of touch panels, and more specifically, to a touch panel and a manufacturing method thereof. Background technique [0002] In the global information age, with the advancement of science and technology and the continuous improvement of living standards, electronic products such as mobile phones and notebook computers are increasingly developed and popularized. Continuous research and development and improvement of the appearance, in order to occupy more markets. [0003] The touchpad is an input component configured on a frame surface such as a liquid crystal display or a cathode ray tube, allowing the user to press from above with a finger or a pen tip in accordance with the instructions on the see-through screen to detect the press position to enter the position. In recent years, with the continuous improvement of the performance and production quality of the touch panel, and the sharp reduction of the price, the t...
