Large-size capacitance screen-based touch display integrated machine and data output method thereof

Abstract

The invention discloses a touch-display integrated machine based on a large-size capacitive screen, which includes a capacitive screen, a display screen and a control device. The capacitive screen includes a first sensing layer, a first adhesive layer and a second sensing layer arranged in sequence. The first sensing layer and the second sensing layer are attached through the first adhesive layer; the second sensing layer of the capacitive screen and the display screen are attached through the second adhesive layer; the first sensing layer and the second sensing layer are connected to each other through the data transmission bus The control device is electrically connected; the display screen is electrically connected to the control device; the invention also provides a data output method of the touch-display integrated machine. The touch-display all-in-one machine based on the large-size capacitive screen of the present invention uses a large-size capacitive screen combined with a display screen to realize a low-cost touch-sensitive all-in-one touch-display machine with a good appearance overall effect, which can be widely used in teaching, seminars and most In the desktop puzzle game, various data can be identified and converted through the data output method, which meets the needs of flexible control of display function and playback format.

Description

technical field [0001] The invention relates to a touch-display integrated machine, in particular to a touch-display integrated machine based on a large-size capacitive screen and a data output method thereof. Background technique [0002] The capacitive touch screen is coated with a layer of transparent special metal conductive material on the glass surface. When the finger touches the metal layer, the capacitance of the contact will change, so that the frequency of the oscillator connected to it will change. By measuring the frequency Changes can determine the location of the touch to obtain information. At present, traditional touch-display all-in-one machines are mainly implemented by projection equipment, infrared screens, or plug-in touch screens, which are complex in structure design, high in cost, low in touch sensitivity and precision, and poor in appearance integration. Considering the advantages of the built-in capacitive screen, its display function is more comp...

AI Technical Summary

Problems solved by technology

At present, traditional touch-display all-in-one machines are mainly realized by projection equipment or infrared screens, or external touch screens. The structural design is relatively complicated, the cost is high, the touch sensitivity and precision are not high, and the appearance integration effect is not good.
