Abstract

The invention relates to an anti-peep display system for a microcomputer system. The anti-peep display system comprises a display card of a microcomputer, a TMDS (Transition Minimized Differential Signaling) data receiving and decoding circuit, a T' trigger, controllable liquid crystal eyeglasses, a driving circuit of a data signal and a control signal, a TMDS data encoding and transmitting circuit and a display, wherein the display card of the microcomputer is connected with the TMDS data receiving and decoding circuit; the TMDS data receiving and decoding circuit is connected with the driving circuit of the data signal and the control signal; the input end of the T' trigger is connected with the TMDS data receiving and decoding circuit; the output end of the T' trigger is connected withthe driving circuit of the data signal and the control signal; the controllable liquid crystal eyeglasses are controlled by the output end of the T' trigger synchronously; the TMDS data encoding and transmitting circuit is connected with the driving circuit of the data signal and the control signal; and the display is connected with the TMDS data encoding and transmitting circuit. According to the anti-peep display system, contents on the display can only be seen by people who operate the microcomputer and an application system thereof, and other people cannot see, so that the anti-peep problem of the microcomputer system is solved.

Description

technical field [0001] The invention relates to an anti-peeping display system of a microcomputer system. Background technique [0002] In many occasions, the user of the microcomputer is unwilling to let the people around him see the display interface of the microcomputer he is operating, such as the ATM machine of the bank, the microcomputer running online banking in the business hall of the bank, or the computer of other business halls. Inquiry machines and computers in public places, etc. [0003] The way to solve the above problems at present is "one-meter line" or blocking with a shielding plate. There is still no solution to the above-mentioned problems at the technical level. [0004] The patent of the present invention, that is, the anti-peeping display system does not solve the above-mentioned problems by means of space isolation, but by means of electronic technology. Contents of the invention [0005] The object of the present invention is to solve the anti-...
