Application.

The description may use the phrases "in one embodiment", "in another embodiment", "in another embodiment", or "in other embodiments", which may refer to the same in accordance with the present application. Or one or more of the different embodiments.

The application provides a display screen. Detailed description will be made one by one in the following embodiments.

The first embodiment provided by the present application is an embodiment of a display screen.

The present embodiment is described in detail below with reference to FIG. 1. FIG. 1 is a schematic diagram of a display screen according to an embodiment of the present application.

The display screen includes a circuit board 1 and a flexible material as a substrate. The electronic chip 2 and the LED lamp 3 are disposed only on the same side surface of the substrate. The electronic chip 2 and the LED lamp 3 are electrically connected to an electronic circuit in the substrate. The LED lamps 3 are arranged on the circuit board 1 in an array for realizing display information output.

The circuit board is one of the important components in the electronics field. As long as the electronic components of the integrated circuit are used, the circuit board is used to connect the electronic components together for the purpose of design.

Flexible material refers to a material that has a certain degree of softness and flexibility. In practical applications, the flexible materials we commonly use are generally polymer materials. For example, clothing fabrics and plastic films in everyday products. The term "flexible material" as used in electronic products refers to materials in the field of wearable materials, such as flexible electrodes, flexible sensors, and the like.

The substrate is the base material. In this embodiment, the circuit board 1 is made of a flexible material as a substrate, that is, the substrate of the circuit board 1 is made of a flexible material. Flexible materials commonly used in circuit boards include FPC materials.

A circuit board made of FPC material (referred to as FPC circuit board) is a circuit board made of polyimide or polyester film with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness and good bending property. However, FPC materials are generally very limited in their use. A small area of FPC board can achieve multi-layer wiring, double-sided patch. However, it is very difficult to use on a large area.

In this embodiment, the electronic chip 2 and the LED lamp 3 are disposed only on the same side surface of the substrate, and the electronic circuit in the substrate is laid in multiple layers; the electronic chip 2 is specifically a patch. With multi-layer wiring, the form of single-sided patch solves the problem that FPC cannot achieve large-size applications. For example, the number of lattices of the basic unit in the LED screen can only be realized on the FPC board is 16×16 (the number of LED lamps and columns on the lamp board), and the visual resolution is only 16 pixels×16 pixels. Only simple animations with one word or similar emoticons can be displayed. The application can realize the product screen size of 24cm×24cm, the number of lattices is 64×64, the visual resolution is 64 pixels×64 pixels, and the optimal viewing distance is 3-10 meters.

The electronic chip 2 includes a display driving chip for obtaining a trigger command for turning on or off the LED lamp 3, and lighting or turning off the LED lamp 3 in response to the trigger command.

A single-chip microcomputer is an integrated circuit chip that integrates computer technology into a piece of silicon using ultra-large-scale integrated circuit technology to form a small and complete microcomputer system. Often used as a circuit control core is widely used.

At present, the smallest single chip microcomputer on the market has a size of 5 cm x 5 cm and cannot be made into a soft patch. In order to make the display screen suitable for the application on the clothing, the present application uses the single-chip microcomputer used in the mobile phone as the control chip, and reduces the size of the single-chip microcomputer to 2cm×4cm. The control chip 4 controls display information of the display screen for attaching to the surface of the substrate, the surface being different from the surface on which the LED lamp 3 is disposed. For example, the control chip is attached to the surface of the substrate using an insulating paste. The control chip 4 is electrically connected to the display driving chip through an interface for transmitting a triggering command for turning on or off the LED lamp 3 to the display driving chip.

The control chip 4 includes a control module and a communication module.

The communication module specifically refers to a 2G mobile communication module. 2G communication is the basic technology in the mobile phone industry. At present, it is widely used in data transmission, GPS positioning and other fields, with low cost, stable data and low transmission failure.

The 2G mobile communication module receives display information and/or control commands according to the mobile communication protocol, and transmits the display information and/or control commands to the control module. For example, after the remote device edits the display information and/or generates the control command, the display information and/or the control command are transmitted to the communication module of the control chip 4 by the 2G mobile communication method. This transmission method can be point-to-point transmission or one-to-many transmission.

The control module 4 receives the display information and/or the control command, and generates a trigger command for generating the LED lamp 3 according to the display information and/or the control command to send to the display driving chip. The control module 4 can make the display information flexible by the control command. For example, the control module stores a plurality of display information, and the control command obtained by the control module sequentially changes the display information every one minute, and the control module changes the display information once every one minute.

The control chip 4 further includes: a power supply interface 5; the display screen receives external power supply through the power supply interface 5. The power supply interface 5 can be an interface that is wired by the control chip 4 to the edge of the screen. For example, the interface is a mini USB interface. The external power supply can be a mobile lithium battery.

In order to prevent the display screen attached to the surface of the garment from being affected by rain or perspiration, the surface of the circuit board 1 and/or the control chip 4 is subjected to a protective treatment; the protective treatment includes: moisture proof treatment and/or anti-salt treatment. And / or anti-corrosion treatment. For example, use a three-coat paint for processing.

The surface of the display LED lamp 3 is covered with a mask 6 of transparent material. For example, a PU fabric is used as a mask for a transparent material, and the PU fabric is laser-cut to complete the appearance. The other side surface of the display LED lamp 3 is covered with a textile fabric 7 having an adsorption function. For example, a woven fabric with an adsorption function. The use of different fabrics before and after the display reduces the lightness of the product, while the softness is not limited. At the same time, since the other side surface of the display LED lamp 3 is made of cloth, the display screen can be easily fixed to the surface of the clothing.

This application is designed using the technical standards of semi-outdoor LED screens, that is, using P2/P3/P4 production standards. Suitable for indoor and outdoor applications where sunlight is not strong. The best visual distance is 3-10 meters, and the text, pictures and videos on the screen can be clearly seen.

A person skilled in the art can clearly understand that, for the convenience and brevity of the description, the electronic device to which the data processing method described above is applied can refer to the corresponding description in the foregoing product embodiment, and details are not described herein again.

The above embodiments are merely exemplary embodiments of the present application, and are not intended to limit the present application, and the scope of protection of the present application is defined by the claims. A person skilled in the art can make various modifications or equivalents to the present application within the spirit and scope of the present application, and such modifications or equivalents are also considered to fall within the scope of the present application.
