Embodiment Construction

[0011] see figure 2 and image 3 , which is a schematic diagram of a screen 20 controlled by optical signals in the present invention. The screen 20 includes a display screen 21, a resistive film screen 22 and a controller 27 that cooperate with the surface of the display screen 21, and the resistive film screen 22 includes a glass screen. Or the basic layer 221 of hard plastic material, the surface of the basic layer 221 is coated with a layer of transparent metal oxide (transparent conductive resistance) conductive layer 222, and the conductive layer 222 is covered with a layer of transparent protective layer 223 again, and the inner surface of the protective layer 223 is also coated with a Layer conductive layer 224, two conductive layers 222,224 are connected to controller 27 respectively, there are many small (less than 1 / 1000 inch) transparent isolation points 226 between two conductive layers 222,224 to separate two layers of conductive layers 222,224 Open insulation....

Abstract

The invention provides a screen controlled by adopting optical signals, which comprises a display screen and a resistor film screen matched with the surface of the display screen, wherein the resistor film screen is provided with two conductive layers which are mutually separated and insulated; a plurality of photoresistors are connected between the two conductive layers; and the photoresistors change the resistance under the irradiation of specific light rays.

Description

technical field [0001] The invention relates to a display screen, in particular to a display screen which can be controlled by light signals. Background technique [0002] With the advancement of science and technology, the input methods of electronic products have also become various. At present, the commonly used input methods include keyboard, mouse, touch screen input, etc., especially touch screen input. Users only need to touch the icons on the screen with their fingers Or text can realize the host operation, so that the human-computer interaction is more straightforward, people use the touch screen instead of the mouse or keyboard. When working, the user first touches the touch screen with fingers or other objects, and then the system locates and selects information input according to the touched icon or menu position. The touch screen consists of a touch detection component and a touch screen controller; the touch detection component is used to detect the user’s tou...
