Abstract

The invention relates to an inductive key which comprises an inductive key board and a light source arranged on the inductive key board. The front face of the inductive key board is provided with a non-inductive area and a plurality of inductive areas; the light source protrudes out of the front face of the inductive key board, a light guide film is arranged on the front face of the inductive key board, and the light guide film is provided with a reflection pit area. Light rays emitted by the light source are projected to the light guide film along the direction parallel to the light guide film, and the direction of propagation is changed by the reflection pit area. The invention also provides an electronic device with the inductive key. The inductive key and the electronic device with the same provided by the invention can realize diversified light shaping effects without arranging light holes in the inductive key board, so that the inductive key is easily beneficial to being thinned, and the cost is reduced.

Description

technical field

[0001] The invention relates to the field of sensor buttons, in particular to a sensor button with a luminous modeling effect and an electronic device with the sensor button. Background technique

[0002] Sensor buttons have been widely used in TVs, monitors, computer notebooks, handheld assistants, speakers, light boxes, CD players, instruments and other electronic devices to achieve function selection. The luminescent structure is arranged on the induction key, which can provide indication function for the user, so as to distinguish the key area and the non-key area.

[0003] With the development of thinner and lighter electronic products, such as flat-panel TVs, especially ultra-thin TVs and other thin electronic products, the front function buttons will use more sensory buttons with light-emitting structures, and the lighting shapes of the light-emitting structures are diversified. It can further play the effect of decoration and beautification, and impr...

Examples

Embodiment approach 1

[0030] Such as image 3 As shown, the embodiment of the present invention provides an inductive button, which can be widely used in various electronic devices such as TVs, especially flat-panel TVs and ultra-thin TVs, monitors, computer notebooks, handheld assistants, speakers, light boxes, CD players, and instruments. Implement function selection. The sensor button of the present invention can be used as an independent modular intermediate product for manufacturers to select and stick to the casing of electronic products such as the TV casing 7 to complete the assembly of the whole machine.

[0031] The sensor keypad provided by the embodiment of the present invention includes an inductive keypad 1 and several light sources 2 arranged on the inductive keypad 1. The inductive keypad 1 can be selected but not limited to the usual capacitive sensing type. image 3 In the embodiment of the present invention, there are two light sources 2. The light source 2 is preferably but not...

Embodiment approach 2

[0041] Such as Figure 12 , 13 As shown, this embodiment provides an electronic device including the sensor button in Embodiment 1, such as a thin flat-panel TV, an ultra-thin TV, a monitor, a computer notebook, a handheld assistant, a speaker, a light box, a CD player or an instrument, etc. etc., and other electronic devices that need to have inductive buttons should also be included in this embodiment. In this implementation manner, an ultra-thin TV is taken as an example for description. Since the present invention relates to the improvement of sensor keys, other existing components of electronic equipment will not be described again.
