Detailed Description
In order to make the technical means and functions of the present invention easy to understand, the present invention is specifically described below with reference to the embodiments and the accompanying drawings.
Example (b):
as shown in fig. 1 and fig. 2, the present embodiment provides an intelligent touch pad 100 with a customized conductive structure, including: the display device comprises a panel 1, a conductive structure 2, a light guide plate 3, a back plate 4 and a touch control playing system 5.
The conductive structure 2 is disposed on the inner wall of the panel 1 for recognizing touch sensing, and when a user touches the panel, the conductive structure 2 generates a capacitance change, thereby obtaining a changed electrical signal. Wherein, the inner wall of different panels has different logos, and different logos correspond relevant audio and video content to reach the purpose of accurate input.
Further, the conductive structure 2 is electrically connected to the input pins of the touch module 52 through the middle channels of the light guide plate 3 and the back plate 4. Thus, when a user touches the area of the panel 1 where the conductive structure 2 is located, the conductive structure 2 is able to transmit a varying electrical signal to the touch module 52.
As shown in fig. 3, the conductive structure 2 is attached to the panel by using conductive ink, conductive paint, conductive tape, and other conductive means, and has a shape designed into different patterns according to requirements, such as LOGO or trademark of company LOGO.
The conductivity of the conductive ink is affected by the kind of conductive material, the particle size, the shape, the filling amount, the dispersion state, the kind of binder, the curing time, and the like. Ag and Cu are widely used conductive ink materials in the metal system. The nano Ag ink has high conductivity and oxidation resistance, but is expensive; the nano Cu printing ink has strong conductivity, low price and easy oxidation; the graphene serving as the novel conductive ink has the advantages of low cost and corrosion resistance. Meanwhile, the conductive paint is a paint capable of being sprayed, is prepared by adding conductive metal powder into a specific resin raw material, and can play a role in conducting after being dried to form a paint film. In addition, the conductive adhesive tape is a metal foil or conductive cloth with a high-conductivity back adhesive, the conductive back adhesive and the conductive base material of the conductive adhesive tape form a complete conductor, and the conductive adhesive tape is a conductive material which is economical and practical and is convenient to use.
Furthermore, the conductive ink can be printed on the inner wall of the panel by an aerosol printing technology, the printing mode is that the nano conductive ink is formed into aerosol by ultrasonic oscillation or airflow, the aerosol is transmitted to an ink jet port by using transmission carrier gas (atomization), and then the conductive ink is printed on a required substrate, namely the inner wall of the panel, by a printing mode. Meanwhile, aerosol printing can utilize a beam of covering gas to cover the outside of the conductive ink to control the direction of printing airflow so as to ensure the printing accuracy. However, the method needs to model the printed pattern in advance, and has certain requirements on the performance of printing equipment and the viscosity of the conductive ink.
Further, the conductive ink and the conductive paint may be printed with patterns on the inner wall of the panel using gravure printing. The printing mode is a printing mode of making the pattern part on the surface of the printing panel dent, spreading the conductive material on the surface, scraping the redundant conductive material by using a scraper blade, and transferring the conductive material to a printing stock by using larger pressure. The method can obtain thicker conductive layer, thereby obtaining conductive structure with high conductivity. In addition, the conductive paint and the conductive adhesive tape can adopt a conductive material transfer method of writing and printing, and a target pattern is formed by directly bonding the conductive material and the panel, so that the operation is visual and flexible, and a low-price printing method is provided for non-professionals.
The light guide plate 3 is fixed with the panel 1 through screws, is provided with a groove 6 for placing the LED lamp strip 51, can fully scatter the LED lamp strip 51, and realizes softer and uniform irradiation effect.
In practical application, the suitable printing material, pattern and mode should be selected in consideration of practical situations such as material cost, printing difficulty, precision requirement and the like.
The back plate 4 is fixed on the light guide plate 3 and used for shielding the touch module 52, the main control module 53 and the wireless communication module 54, so that the beauty of the panel 1 is improved.
In this embodiment, the back plate 4 and the light guide plate 3 are provided with an interface for electrically connecting the conductive structure 2 and the touch module 42.
As shown in fig. 4, the touch playing system 5 is fixed on the back panel 4 and configured to control the playing device 7 to play video and audio, and includes an LED light bar 51, a touch module 52 electrically connected to the conductive structure 2 and configured to obtain a touch signal, a main control module 53 electrically connected to the touch module 52 and configured to receive an electrical signal and then form a touch signal to control the LED light bar 51 to turn on or off, and a wireless communication module 54 electrically connected to the main control module 53 and communicatively connected to the playing device 7 to further control the playing device 7.
Specifically, the input pin of the input end of the main control module 53 is electrically connected to the output pin of the touch module 52, so that the touch module 52 can transmit the touch signal to the main control module 53, and the main control module 53 can receive the touch signal. An output pin of the output end of the main control module 53 is electrically connected to the LED light bar 51 to control the on/off of the LED light bar 51 on the board, and the other end of the LED light bar 51 is connected to the power supply or the ground.
In addition, an output pin of the output terminal of the main control module 53 is electrically connected to the input terminal of the wireless communication module 54 to control the wireless communication module 54 to operate. The wireless communication module 54 can remotely control the playing device 7 to play the corresponding video and audio signals.
In this embodiment, the playing device 7 adopts a liquid crystal display, an LED display, a projection device, or the like, and the transmission mode between the wireless communication module 54 and the playing device 7 is NB-IoT, LORA, WIFI, bluetooth, zigbee, or other communication modes.
The working process of the intelligent touch pad with the customized conductive structure of the embodiment is as follows:
in the intelligent touch pad 100 with the customized conductive structure of the present embodiment, when the user touches the area of the conductive structure 2, the hand of the user will generate a capacitance change with the conductive structure 2. The conductive structure 2 transmits the varying electrical signal to the touch module 52 to form a touch signal. After receiving the touch signal sent by the touch module 52, the input end of the main control module 53 outputs and controls the LED light bar 51 and the wireless communication module 54 to work. For example, when a user touches a panel with a LOGO of a company, the LED light bar on the panel can be lighted and the remote control playing device 7 can play the introduction video of the company.
