Embodiment Construction

[0031] figure 1 It is a principle block diagram of realizing backlight adjustment of an existing LCD TV or LCD display. Such as figure 1 As shown, the backlight adjustment of the existing LCD TV or LCD display is realized by the device shown in the figure, including: LCD backlight adjustment module 11 , LCD module 12 and remote controller 13 .

[0032] The LCD backlight adjustment module 11 is a module that is present in LCD TVs or LCD displays with backlight adjustment function, and is mainly used to realize backlight adjustment. In the prior art, the adjustment of LCD backlight is realized by pulse width modulation (PWM) signal, which is to use the principle of persistence of vision of the human eye to periodically control the rapid opening and closing of LCD backlight with a certain frequency and duty cycle. ;In practical applications, the frequency of PWM dimming is generally above 100Hz, so the human eye will not see the light flicker generated by PWM dimming, and the h...

Abstract

The invention relates to a method and a device for transmitting data, in particular to a method and a device for transmitting data by utilizing LED backlight. The device comprises an encoder, an LCD backlight adjusting module, an LCD module, an optical sensor and a decoder, wherein the encoder is arranged on an LCD television or an LCD display and used for encoding the data to be transmitted and converting the data to a proper backlight control signal; the LCD adjusting module is used for carrying out backlight adjustment; the LCD module set is used for transmitting encoded data to be transmitted as an optical signal; the optical sensor is arranged on a user remote controller and used for receiving the LCD backlight signal; and the decoder is used for carrying out decoding operation on the received encoded signal. When the method and the device for transmitting the wireless data of the invention are adopted, the data transmitting function can be conveniently added to the LCD television or the LCD display, the change of the system is small, and the cost is low.

Description

technical field [0001] The present invention relates to a data transmission method and device, more specifically, to a wireless data transmission method and device. Background technique [0002] If the existing LCD TV or LCD monitor wants to realize the wireless data transmission function (for example: send the current program information etc. The sending module properly encodes the information to be sent to the corresponding receiving device (such as a remote control) with data receiving function, and the receiving device restores the received information through the decoder and displays it to the user. Therefore, it is necessary to add a data sending module on the LCD TV or LCD display. [0003] The existing technology has the following disadvantages: due to the need to add an additional data transmission function module, it will inevitably lead to an increase in development costs; in addition, on a platform without this function, if this function needs to be added, the c...
