Description

TECHNICAL FIELD

[0001] The utility model relates to screen adjustment technical field especially is a kind of touch screen of hierarchical adjustable brightness. BACKGROUND

[0002] Resistive touchscreen: Resistive touchscreen is an early adopted touch screen technology. It consists of two layers of transparent film with conductive coating, and the two layers of film are separated by a small gap. When the user touches the screen with a finger or other object, these objects will be pressed between the two layers of film, causing the coating to contact each other, thereby changing the flow of current. By measuring this current change, the touch position can be accurately determined. Capacitive touchscreen: Capacitive touchscreen uses a layer of transparent capacitive layer to detect touch action. When the user touches the screen with a finger, the capacitive layer will form a changing electric field, thereby changing the current in the sensor. By detecting this current change, the touch position can be determined. Capacitive touchscreen can provide higher accuracy and response speed, and supports multi-point touch better. Surface acoustic wave touchscreen: Surface acoustic wave touchscreen detects touch by transmitting acoustic waves on the surface of the touchscreen. The edge of the touchscreen is provided with a transmitter and a receiver, and the acoustic waves formed between them are reflected on the surface of the screen. When an object touches the screen, the acoustic waves will be blocked or scattered, thereby causing interference between the sensors. By detecting this interference, the touch position can be accurately determined. Surface capacitive touchscreen: Surface capacitive touchscreen is similar to capacitive touchscreen, but adds small sensing electrodes on the transparent capacitive layer on the screen surface. When the user touches the capacitive screen, the current distribution in the electric field will change, so that the touch position can be detected. Surface capacitive touchscreen is suitable for large touch screens, and has high transparency and durability.
