Backlight device of touch-type remote controller

Abstract

The invention discloses a backlight device of a touch-type remote controller. The backlight device comprises a PCB (2), and light emitting diodes (3), wherein the front face of the PCB (2) is provided with at least one group of touch-type keys (4). The backlight device of the touch-type remote controller is characterized in that: the PCB (2) below each touch-type key (4) of each group is provided with transmittance holes (5); on the back face of the PCB (2), each group of transmittance holes (5) is provided with a light guide groove (1); and the two ends of the light guide groove (1) are respectively provided with the light emitting diodes (3). By making use of the characteristic that the light guide groove can make light distribute uniformly, the backlight device of the touch-type remote controller makes use of fewer light emitting diodes to achieve a better backlight effect, and can achieve the beneficial effects of cost conversation, low power consumption and stable circuit when achieving the technical effect of effective backlight.

Description

technical field [0001] The invention belongs to the technical field of remote control, in particular to a backlight device of a touch-type remote control. Background technique [0002] With the continuous development of social economy, various electrical appliances have become daily products in common people's families, such as TV, air conditioner, DVD, home theater and so on. In order to facilitate the operation and use of these household appliances, they are generally equipped with remote controls. With the rapid development of touch technology, it has also been rapidly developed in the field of remote controls for daily products, and is more and more popular with people for its lightness, bright appearance and good feel. Among the existing touch-type remote controllers, there are still some remote controllers without any backlight, and it is difficult to identify the function of the buttons when using the remote controller in a dark place, and some remote controllers use...

AI Technical Summary

Problems solved by technology

Among the existing touch-type remote controllers, there are still some remote controllers without any backlight, and it is difficult to identify the function of the buttons when using the remote controller in a dark place, and some remote controllers use a setting under each touch button. A light-emitting diode realizes the backlight function of the remote control. As the functions of home appliances are becoming more and more powerful, there are correspondingly more function keys on the remote control. If this method is used to realize the backlight function, a large number of light-emitting diodes must be installed. The technical solution of placing light-emitting diodes directly under the touch keys not only has the disadvantages of light divergence and poor control, but also increases the cost with the increase of the number of light-emitting diodes, which consumes more power, and the corresponding increase in solder joints also brings come more unstable factors
