Inductive key and electronic device with same

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...

AI Technical Summary

Problems solved by technology

[0005] 1. In order to achieve the luminous effect of the sensor button, it is necessary to open a light-transmitting hole 3 on the sensor button board 1, so that the light of the LED light 2 can be transmitted to the front of the product, which will destroy the circuit layout and induction of the sensor button board 1. The structural strength of the keypad 1 itself

[0006] 2. The luminous effect is realized by making the light pass through the light-transmitting hole 3. In this way, when the size of the sensor button is fixed, if you want to change the luminous shape, for example, increase the area of ​​the light-emitting area by increasing the light-transmitting hole 3, you must reduce the sensor The area of ​​area 4 will sacrifice the sensitivity of the sensor buttons. Based on this limitation, the existing sensor buttons have a single lighting shape, and it is not easy to realize the diversification of lighting shapes.

[0007] 3. For each light-emitting point on the sensor button, it is necessary to set an LED lamp 2. The usage of LED lamp 2 is large, and opening the corresponding light-transmitting hole 3 on the sensor key board 1 also increases the complexity of the process. Degree and processing man-hours, the cost of sensor buttons is higher
