Backlight indicator used by controller and provided with correction film and manufacture method thereof

Abstract

The invention discloses a backlight indicator used by a controller and provided with a correction film. The backlight indicator comprises a backlight indicator basic body, a backlight color domain pad printing film and the light-transmitting correction film. A light-transmitting area is arranged on the end surface of the backlight indicator basic body, a correction film arranging area larger than the light-transmitting area is arranged on the inner side of the backlight indicator basic body corresponding to the light-transmitting area, the backlight color domain pad printing film is attached onto the light-transmitting area in printing mode, and the light-transmitting correction film is attached onto the correction film arranging area in sticking mode. A manufacture method of the backlight indicator used by the controller and provided with the correction film is further disclosed. According to the technical scheme, flaws of parts provided with backlight color domains and used in the controller brought by uneven color and poor impression degree due to various conditions happened on several parts in the manufacture process can be effectively overcome and compensated, part rejection rate is reduced or avoided, and product qualified rate is greatly improved. In addition, the manufacture method is simple in process, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning controllers, in particular to a controller backlight indicator with a correction film and a manufacturing method thereof. Background technique [0002] Backlight color gamut technology is more and more applied to the manufacture of automobiles, electronics, home appliances, communications and other parts. There will be defects caused by uneven color and poor perception of individual parts due to various reasons (such as mold defects, part attachments, tiny bubbles in the pad printing layer, impurities, and particles in the manufacturing environment). It is also possible to engrave the bumps away, resulting in a thinner light-transmitting color film at this point and forming a light color spot. [0003] In the book "Mechanical and Electrical Technology" published in the fourth issue of 2006, the article "Application of In-mold Injection Molding Technology in Automotive Air Cond...

AI Technical Summary

Problems solved by technology

[0007] The first purpose of the present invention is to solve the problem of the backlight parts for controllers with backlight color gamut in the prior art. Due to the uneven color and poor perception in the backlight color gamut, the light-transmitting color film is thin and light-colored. A backlight indicator for a controller with a correction film that improves, compensates for defects caused by uneven color and poor perception, and reduces or avoids scrapped parts
