Imaging touch control film and large-screen interactive media system applying imaging touch control film

Abstract

The invention discloses an imaging touch control film. The imaging touch control film comprises a back projection imaging film with back projection imaging function, an electromagnetic induction layer consisting of ultrafine conducting wire grids and a transparent protective film which are orderly attached. The imaging touch control film has lower cost, high recognition precision and long service life, is convenient for assembly and disassembly, and is convenient for mass application. The invention also discloses a large-screen interactive media system applying the imaging touch control film, the large-screen interactive media system comprises the imaging touch control film which is adhered to the rear side of thick sheet glass as well as a controller and a data processor which are connected with the large-screen interactive media system, an output end of the data processor is connected to a liquid crystal display screen or a projector through a VGA, and another output end is connected to an audio through an audio output port. The large-screen interactive media system has the advantages that the large-screen interactive media system saves energy sources, reduces light pollution, has safe use, and is suitable for various occasions, thereby achieving active interactive media effect.

Description

technical field [0001] The invention relates to an imaging touch film, in particular to a functional film with a built-in ultrafine wire grid electromagnetic induction layer for touch control and rear projection imaging, which belongs to the technical field of materials and electronics. Background technique [0002] With the wide popularization and application of computer technology, the electronic and digital channels of information are becoming more and more abundant. People use various peripherals of computers to realize various methods to complete the initial digitization process of information processing. For example: various keyboard input methods, voice input, image acquisition, etc., among which the most effective and convenient one is to directly input information and command through touch and click. Such as, when utilizing computer drawing drawing, because utilize mouse operation can't really be as flexible as the operation that people use pen to draw on paper, an...

Problems solved by technology

Today's small-size LCD touch screens cannot perform rich and colorful multimedia applications due to their small screen size and weak expressiveness, while large-size LCD touch screens limit the application of large-size LCD touch screens due to factors such as large power consumption, space occupation, and high price.

The emergence of projection imaging film and electromagnetic induction touch film solves the disadvantages of large-size touch LCD screens. However, two films need to be used at the same time to achieve imaging and touch functions. Professional film stickers are required to install and install. The procedures are cumbersome and inconvenient to disassemble, often causing damage to the imaging film

Due to the separation of touch film and imaging film, the application difficulty of touch film and projection imaging film is increased, which limits the promotion and application of touch film and imaging film

[0003] In addition, in the real-life media system, outdoor static advertisements and one-way video advertisements are the most used. These two media methods are one-way indoctrination communication, it is difficult to resonate with consumers, so the effect is not very good

Moreover, the LED advertising screens used in video advertising media consume power and cause light pollution.
