Embodiment Construction

[0016] The radio frequency induction liquid crystal screen of the present invention, its specific embodiment is, select suitable transparent material, built-in wireless induction coil, the display unit that is made of liquid crystal screen and backlight LED, supercapacitor, control unit and beating detection device, be assembled into response only Waterproof RF-sensing LCD screen with specific high-frequency alternating magnetic field.

[0017] In order to save the cost of the control unit, a single-chip microcomputer can be used as the control unit and generate random numbers.

[0018] The control unit generates a trigger control signal according to the change of the external magnetic field or collects the user's slapping or touching action, controls the display of the LCD screen randomly or according to specific rules, and controls the working current, which is fed back to the external alternating magnetic field.

Abstract

The invention discloses a radiofrequency sensing liquid crystal display. The radiofrequency sensing liquid crystal display is characterized in that a wireless sensing coil capable of matching with high-frequency alternating magnetic field, a charging unit and a low-power-consumption liquid crystal display panel are built in, and the wireless sensing coil charges the charging unit. The radiofrequency sensing liquid crystal display can generate a trigger control signal randomly or after detecting a change in the alternating magnetic field, thus controlling display of the radiofrequency inductive liquid crystal display to change. The radiofrequency sensing liquid crystal display is low in cost and power consumption and is, accordingly, especially applicable to wireless sensors.

Description

technical field [0001] The invention relates to the technical field of wireless induction power supply and detection and the field of interactive games, in particular to a radio-frequency induction liquid crystal screen capable of sensing an external high-frequency alternating magnetic field, and capable of randomly controlling the display of the liquid crystal screen. technical background [0002] In recent years, wireless charging technology has gradually become popular, and most of them are used in the field of mobile phone charging. However, at present, there has been no major breakthrough in the method of realizing wireless power control and interactive control of large-scale desktops. If the overall desktop can be equipped with charging and gaming functions, multiple radio-frequency sensing LCD screens can cooperate with wireless sensing desktops to realize game effect upgrades and multi-functions. rules of the game. [0003] The purpose of the product of the present ...
