Abstract

The invention provides a device for changing the color of a designated position of a screen by transmitting position data through the screen and receiving position information point by point, which comprises a handheld terminal and a processor. The processor transmits position data through the screen, the handheld terminal collects and transmits color information of a changed designated position to the processor, and the processor processes the information and then sends display information to the display to display. Therefore, the handheld terminal and the processor can change the color of the designated position of the screen.

Description

Device for changing color of designated position of screen by transmitting position data through screen and receiving position information point by point

Technical Field

The present invention relates to a screen-specific display method, and more particularly, to an apparatus for changing a color of a designated position of a screen by transmitting position data through the screen and receiving position information on a point-by-point basis.

Background

At present, with the continuous development of multimedia and touch screen technologies, touch capacitive screens and piezoresistive screens are more and more popular in multimedia classrooms. Such multimedia devices are mostly composed of touch screen devices, display devices, and projection devices or super-large liquid crystal displays, which are expensive to manufacture. Not only the total price is expensive, but also a large amount of manpower and material resources are needed for maintenance, the wiring construction among equipment and the like also occupy a large amount of space, and the failure rate of the mutual matching among multiple equipment is high.

Disclosure of Invention

In view of the above, the present invention provides an apparatus for changing a color of a designated position of a screen by transmitting position data through the screen and receiving position information point by point, which includes, but is not limited to, a handheld terminal and a processor, wherein the handheld terminal collects screen phenomenon information and display pixel position information and transmits the information to the processor, and the processor analyzes the information and then changes the designated color of a corresponding position and a display point according to an instruction. The color, the character image and the like of the appointed position of the screen can be changed at any time through the method.

The invention aims at a device for changing the color of the appointed position of the screen by transmitting position data through the screen and receiving position information point by point, which can solve the problem of high error probability when a plurality of devices are matched with each other and can solve the problems of wiring and space occupation.

According to the embodiment of the invention, the device for changing the color of the designated position of the screen by transmitting the position data through the screen and receiving the position information point by point comprises a handheld terminal and a processor, wherein the processor transmits each pixel information to the display, the handheld terminal outputs the confirmed screen information to the processor, and after the handheld terminal designates one or more points of the screen, the handheld terminal transmits a signal to the designated position of the screen after processing and changes the designated color for display.

In summary, in the screen display device according to the embodiment of the present invention, the processor transmits the screen pixel signal to the screen for displaying, the handheld terminal confirms the information and sends the color information for changing the designated point to the processor, and the processor changes the designated color of the designated point on the screen according to the instruction of the handheld terminal, so that the display problem of the screen and the multimedia classroom screen can be solved by using the device for transmitting the position data through the screen and receiving the position information point by point, and the device is convenient to move and carry compared with the existing multimedia devices, and has the characteristics of being capable of rapidly mounting the device without excessive debugging.
