Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as Figure 3-6 and Figure 8 Shown is the preferred embodiment provided by the present invention.

[0036] It should be noted that, when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0037] It should also be noted that the orientation terms such as left, right, up, and down in this embodim...

Abstract

The present invention relates to the technical field and provides a backlight touch key which comprises a panel which is provided with a touch key. A PCB is attached under the panel. The PCB is provided with a light source for projecting light toward the touch key opposite to the touch key. The outer periphery cover of the light source is provided with a backlight structure for uniformly dispersing the light emitted by the light source. After the light emitted by the light source is uniformly dispersed by the backlight structure, the light is projected to the touch key, then after the light is homogenized by touch key which is a translucent material, uniform backlight is formed on the touch key by the light, and thus the backlight touch key has the advantages of good control effect, small space occupation, flexible backlight control, uniform backlight and low cost and is suitable for a single LED control large character touch key.

Description

technical field [0001] The invention belongs to the technical field of touch keys, and in particular relates to a backlight touch key. Background technique [0002] With the development of electronic technology, the design direction of various electronic products is developing in the direction of thinness and ease of use, striving to integrate more functions in as small a volume as possible, and at the same time control production costs while improving product appearance. Traditional mechanical keys are gradually replaced by more compact touch keys or touch screens due to their high cost and large size, and touch keys are increasingly used in electronic products due to their low cost. [0003] The structure of the touch key includes: a panel that is arranged on the outermost side of the backlight structure and carries the touch key, a circuit board that enables the touch key to realize the manipulation function, and a key board that forms a printed circuit on the surface. In...
