Description

Light-emitting device of touch panel

Technical Field

The utility model relates to the field of notebook equipment, in particular to a light-emitting device of a touch panel.

Background

The conventional touch pad (touch pad) does not have a light emitting effect, generally has a simple track input mode, and is often used to replace the input function of a mouse. In order to satisfy a variety of input modes, a new application of a touch panel, i.e., a light-emitting touch panel device combining a touch panel and a backlight module, has appeared on the market. Taking most of the light-emitting touch panel devices as an example at present, when the light is not emitted, a mode (track detection) of a general touch panel is executed, for example, to operate a mouse cursor; when the light is emitted, a specific pattern can be displayed, and a function corresponding to the specific pattern, such as displaying a numeric keypad, and executing a touch input mode, can be executed. It will be appreciated that the specific pattern is typically where the light emitting area is located.

The main components of the light-emitting touch panel device include a plurality of stacked films and a circuit board provided with light-emitting elements, and the layers are usually bonded by water glue. In order to avoid the situation that the touch system judges the wrong shape, the water gel is distributed in the area where light does not need to be emitted, so that the surface of the touch pad is flat and is not easy to deform under the touch of a user, and the situation that the touch signals are inconsistent is avoided.
