Description

Electronic product and LCD thereof

Technical field

The utility model relates to the electronic product field, is specifically related to the improvement of the LCD display structure of electronic product.

Background technology

Existing electronic product operated by rotary motion has display screen to be used for the information demonstration, and present display screen generally adopts LCD, and along with the increase of LCD area, the energy consumption of LCD backlight also increases.In field of mobile phones, after tested, when LCD is the brightest, the about 120mA(4V of the backlight power consumption of 4 inches screens power supply), the power consumption of 5 inches screens is about the 200mA(4V power supply), LCD(or LCD backlight) become the parts of the power consumption of mobile phone.

The structure of LCD of the prior art comprises along the reverse direction of its light of launching (arrow among Fig. 1): first Polarizer, 1, the first glass substrate 2 as shown in Figure 1 successively, colored filter 3, public electrode 4, liquid crystal 5, show electrode 6, second glass substrate 7, second Polarizer 8, diffuser plate 9, light guide plate 10, reflecting plate 11 also comprises the backlight 12 that is arranged between light guide plate 10 and the reflecting plate 11.

Polarizer is actually a kind of lines more intensive " grating ", and light can only pass through from grating, and other places then can not be passed through.After tested, the light that backlight 12 sends has only 1/2 can pass through second Polarizer 8, and remaining light has only 1/3 can pass through colored filter 3, consider the transmittance of first glass substrate 2, second glass substrate 7 and liquid crystal 5 again, the aperture opening ratios of display screen etc., the luminous energy of actual transmission display screen is less than 10%.

Therefore, the luminous energy major part of the backlight 12 among the LCD is not used for Presentation Function but waste, and the luminous energy of these wastes simultaneously is absorbed in LCD and converts heat energy to, increased the thermal value of LCD.

The utility model content

The purpose of this utility model is to provide a kind of LCD, is intended to solve the waste problem of the luminous energy among the LCD of prior art.

For this reason, the utility model is by the following technical solutions:

A kind of LCD, powered by power circuit, described LCD comprises first Polarizer, first glass substrate, colored filter, public electrode, liquid crystal, show electrode, second glass substrate, second Polarizer, diffuser plate, light guide plate and reflecting plate successively along the reverse direction of its light of launching, and also comprises the backlight that is arranged between described light guide plate and the described reflecting plate;

Described second Polarizer is provided with photoelectricity conversion thin film with respect to the one side of described backlight, and described photoelectricity conversion thin film is electrically connected with described power circuit.

The utility model also provides a kind of electronic product, comprises above-mentioned LCD, also comprises energy-storage battery and is the power circuit of described LCD power supply, and described energy-storage battery is electrically connected with described LCD by described power circuit.

The LCD that the utility model provides, be provided with photoelectricity conversion thin film at described second Polarizer with respect to the one side of described backlight, when LCD works, the light that described backlight is launched is transmitted to described second Polarizer " grating " normally to be passed through when locating, be transmitted to " grating " local time in addition and then absorbed by described photoelectricity conversion thin film and be converted to electric energy, the electric energy of described conversion is the LCD power supply by described power circuit.Therefore, the LCD that the utility model provides, but the luminous energy that is not used for Presentation Function that the described backlight of effective recycling is launched reaches purpose of energy saving; Simultaneously, owing to recycled the described luminous energy that is not used for Presentation Function, reduced the thermal value of LCD.

The electronic product that comprises the above LCD that the utility model provides, but the luminous energy that is not used for Presentation Function that the backlight of the described LCD of effective recycling is launched reaches purpose of energy saving; Simultaneously, owing to recycled the described luminous energy that is not used for Presentation Function, reduced the thermal value of electronic product.
