An embodiment of the invention provides a touch key module. The touch key module comprises a touch screen, a luminescence portion, a first conductive portion, a second conductive portion and a power supply, wherein the touch screen is provided with a touch key character; an area of the touch screen, where the touch key character is located, is a transparent area; the luminescence portion is a cold light sheet; the cold light sheet includes a basal layer, a first conducting layer, a luminescent layer, an electronic transmission layer and a second conducting layer which are successively stacked and arranged; the cold light sheet directly faces the transparent area; a first surface of the basal layer is an emergent light surface, is bonded with an inner surface of the touch screen and covers the transparent area; a second surface of the basal layer is contacted with the first conducting layer; one end of the first conductive portion is electrically connected to the first conducting layer; the other end of the first conductive portion is electrically connected to the power supply; and one end of the second conductive portion is electrically connected to the second conducting layer and the other end of the second conductive portion is electrically connected to the power supply. The embodiment of the invention provides a mobile terminal. The cold light sheet is arranged in an inner surface of the touch key character and gives out light so that brightness and uniformity are ensured to satisfy a requirement.
Description
technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a touch key module and a mobile terminal. Background technique [0002] The optical effect of the touch button of the mobile terminal generally requires moderate brightness and high uniformity, while ensuring that the optical structure is as simple as possible, and the space occupied by the thickness is as small as possible, which is convenient for the stacking design of the mobile terminal. In the prior art, the optical structure of the touch key module of the mobile terminal, such as figure 1 As shown, mainly a top-emitting LED (Light Emitting Diode, light emitting diode) lamp 101 transmits light to the touch key character area 105 of the touch screen 104 through the light guide film 103 . If the light-emitting surface of the LED lamp 101 is more than 1.0mm away from the inner surface of the touch screen 104, it is necessary to design a light guide column 102 to stren...
