[0044] Electromagnetic shielding glass is a kind of light-transmitting shielding device against electromagnetic radiation and electromagnetic interference, involving many fields such as optics, electricity, metal material, chemical raw material, glass and machinery, and is widely used in electromagnetic compatibility field. It is divided into two types of wire screen sandwich type and plating type. The wire screen sandwich type is synthesized by glass or resin and shielding wire screen made by special process at high temperature, attenuates electromagnetic interference through special process, does not distort various observed patterns (including dynamic color image) for the shielding glass, has the characteristics of high fidelity and high definition, and also has the characteristics of explosion-proof glass. The electromagnetic shielding glass mainly solves the electromagnetic interference between electronic systems and electronic equipment, prevents electromagnetic information leakage, protects against electromagnetic radiation pollution, effectively protects the normal work of instruments and equipment, protects the safety of confidential information, and protects the health of workers. Electromagnetic shielding is one of the effective methods for suppressing electromagnetic interference widely used in electromagnetic compatibility engineering.

[0045] As an example, in the embodiment, the electromagnetic shielding film can be made of a film with conductive properties (Ag, ITO indium tin oxide, etc.), can be plated on glass, or other substrates such as plastic film, and the main performance indicators of the material are light transmittance and shielding effectiveness, that is, what percentage of energy is shielded.

[0046] As an example, in the embodiment, the drive board has powerful video processing capabilities such as image position and phase automatic calibration, end image saturation, sharpness enhancement adjustment, and image local enhancement; has 2-way video channels with 1-way VGA signal and 1-way DVI signal input for secular switching; the output interface is a double-channel LDVS, which can support a TFT liquid crystal screen with a resolution of 1920X 1200; the system uses a high-efficiency power supply processing system with voltage wide range input, overcurrent protection, reverse connection protection, high efficiency, low EMI and other characteristics; the board card is strictly controlled in production process, and industrial-grade components are used for conventional and core components to ensure that the LCD drive board works normally in a wide temperature range (-40℃ ~ 80℃) and other harsh environments; it is suitable for liquid crystal display control systems in special fields such as industrial control, military and ship.

In order to solve this problem, an AC to DC power module is designed inside the 12.1 inch display. The power supply is a low ripple and low power consumption power supply, which considers the influence of electromagnetic shielding and the problem of power consumption in design.

[0048] As an example, AC / DC module makes alternating current 220V to direct current 12V power supply design principle is: first is to 220V high voltage transformer, the turns ratio of transformer is determined according to the lower circuit. The current after transformation is still alternating current, and becomes pulse direct current after passing through rectifier circuit. The filter circuit can eliminate the pulse, but the output of the residual voltage is still unstable. Finally, through the voltage stabilizing circuit, the voltage is stabilized.

[0049] As an example, the contact on the thin film key is located on the conductive part on the PCB board (mostly above the gold finger on the circuit board), when the key is pressed by external force, the center point of the contact is concave, contacts the circuit on the PCB, thereby forming a loop, current passes through, and the whole product can work normally.
