The display screen is one of the key hardware of the notebook, accounting for about a quarter of the cost. The display screen is mainly divided into LCD and LED. Among them, LCD refers to liquid crystal display, mainly including TFT, UFB, TFD, STN and other types of liquid crystal display.

Laptop LCD screens are commonly used as TFTs. TFT screens are thin-film transistors, which are active matrix liquid crystal displays. Special light pipes are set on the back of the screen to actively control each independent pixel on the screen, which can greatly shorten the response time and effectively The ability to play dynamic pictures has been improved. Compared with STN, TFT has excellent color saturation, reduction ability and higher contrast, and it can still be seen clearly under the sun, but the disadvantage is that it consumes more power and costs more.

The position detection module within the frame of the horizontal electronic whiteboard locates the X-axis coordinates of the electronic whiteboard pen, and the position detection module within the frame of the vertical electronic whiteboard locates the Y-axis coordinate of the electronic whiteboard pen.

The specific operation is:

The RF transmitting module in the electronic whiteboard pen transmits a connection signal to the RF receiving module of the electronic whiteboard main body,

The control module receives the signal from the RF receiving module, the position record module records the position information of the electronic whiteboard marker detected by the position detection module, and the control module continuously transmits the position information data sent by the position record module to the data conversion module to record the position information , depict the trajectory of the electronic whiteboard pen through the continuously recorded position information; the data conversion module converts the position information into a data format conforming to the human-computer interaction protocol; the interface module provides the data converted by the data conversion module to the notebook computer;

When the whiteboard pen stops writing and drawing, the RF transmitting module in the electronic whiteboard pen transmits a disconnection signal to the RF receiving module of the main body of the electronic whiteboard,

When the control module receives the disconnection signal of the RF receiving module, the control module stops transmitting the location information sent by the location recording module to the data conversion module, and stops recording the location information.

Among them, when the electronic whiteboard pen is pressed to write and draw, a certain section of the continuous infrared diode receiving and receiving light path in the horizontal direction of the X axis is blocked, and the position data of this part of the light emitting diode is transmitted to the position recording module, and the position recording module calculates according to the blocked part of the infrared diode. The center point of the blocked part is used as the real-time X-axis information of the whiteboard pen; at the same time, a certain section of the continuous infrared diode receiving and receiving light path on the Y-axis is blocked, and the position data of this part of the LED is sent to the position recording module. Some infrared diodes calculate the center point of the blocked part as the real-time Y-axis information of the whiteboard pen. The X-axis information and the Y-axis information are sent to the control module by the position recording module as position information data.

In order to be more easily recognized by the operating system, the data conversion module can convert the above position information into a data format conforming to the HID human-computer interaction protocol, and then use the interface module to edit the data signal for use by the notebook.
