Abstract
The utility model provides a backlight display device for touch keystrokes of an electromagnetic oven. The backlight display device comprises a panel, a touch inductor board and a display control panel which are sequentially arranged from the top down, wherein the panel is made from a diaphanous material, keystroke identification marks are arranged on the surface of the panel, and a light shield layer is correspondingly covered on the surface of the panel where the keystroke identification marks are not arranged; and the touch inductor board is clung to the lower surface of the panel and connected with the display control panel through conductive lead wires. The backlight display device is characterized in that the touch inductor board is a transparent flexible diaphragm board, light-emitting elements are arranged on the upper surface of the display control panel and correspond to the underneath of the keystroke identification marks, and light guiding supports are arranged at the peripheries of the light-emitting elements. In the backlight display device, the touch inductor board and the control display panel are separately arranged, the light-emitting elements are directly arranged right below the keystrokes, and light sources are transmitted to the panel through the light guiding supports, so that the backlight effect of the touch keystrokes is more exquisite and vivid. The backlight display device has the advantages of simple and convenient structural design, and good backlight display effect, and is low in cost because common SMD (Surface Mounted Device) LED lamps serve as the backlight.
