Abstract
The utility model discloses an LED liquid crystal display with adjustable colors, which belongs to the field of automated machinery. The LED liquid crystal display with the adjustable colors comprises a full-spectrum backlight module, a display mainboard and a liquid crystal display screen; the full-spectrum backlight module includes a plurality of light-emitting cylinders; each light-emitting cylinder includes a plurality of LED light-emitting tubes with different wave spectra; the LED light-emitting tubes with the same wave spectrum are parallelly connected onto the same control line of the display mainboard; and the display mainboard is connected with the liquid crystal display through a data line. Compared with the prior art, the LED liquid crystal display with the adjustable colors is capable of arbitrarily adjusting brightness and colors and realizing color images from black and white to arbitrary single color to arbitrary color temperature, and has wide market prospect.
Description
Technical field
The utility model relates to a kind of LCD of LED color tunable, belongs to the automated machine apparatus field.
Background technology
At present, for the backlight liquid crystal display module, mainly contain two kinds of patterns of cathode fluorescent tube (CCFL) and LED-backlit.
For cathode fluorescent tube (CCFL) backlight mode, there is high-power shortcoming in it, and mercury metal is necessary element in process of production, there is the operating voltage height simultaneously, expends shortcomings such as the energy is big, serviceable life is short, but because its price is lower, still occupy certain market share at present, but because the many disadvantages of its existence, it can be replaced by the LED-backlit pattern gradually.
The LED-backlit pattern is as new things, again and again impressive on market, though it can bring a lot of benefits technically, such as can allow indicator screen brightness more evenly, lower, the profile of product power consumption can more frivolous fashion, but what generally adopt in the market is W-LED (white light LEDs) backlight; In fact, this backlight only is that luminous components and parts have been changed, and shortcoming to some extent all on display color and homogeneity be we can say aspect the lifting of display effect very faintly, even does not promote, and it can not realize full spectrum in theory simultaneously.
Therefore, all there is weak point in two kinds of present backlight modes, and the former is unfavorable for environmental protection, and latter's color is undesirable, also makes product can't enter the high, refined, peak products ranks.
The utility model content
The purpose of this utility model is to provide a kind of LCD of LED color tunable.At present LED-backlit module displays device popularize the luminous problem that suffered main resistance is LED energetically, it is not full spectral light in theory;
The utility model not only remedies this defective, realizes the full spectrum function of display; And can make any adjustment of LCD realization to brightness and color.The utility model proposes to be made up of the LED luminotron of different chromatograms the module backlight of full spectrum on the basis of traditional LED-backlit module; And distinguish independently different drive controlling for different spectrum, thereby can realize any adjustment brightness and color.
The technical solution of the utility model is:
A kind of LCD of LED color tunable is characterized in that comprising full spectrum module backlight, display main board and LCDs; Described full spectrum module backlight comprises some pillar made of LED plate, and each described pillar made of LED plate comprises the LED luminotron of some different wave spectrums; Wherein the LED luminotron of same wave spectrum is connected in parallel on the same control line of described display main board; Described display main board is connected with described LCD through data line.
Further, described pillar made of LED plate comprises the LED luminotron of three kinds of wave spectrums of red, green, blue.
Further, described pillar made of LED plate comprises red, blue, green and other any or the LED luminotron of several wave spectrums.
Further, described pillar made of LED plate evenly distributes and constitutes described full spectrum module backlight.
Further, described display main board comprises a control module, is used for controlling respectively the LED luminotron strength of current of different wave spectrums.
Compared with prior art, the beneficial effects of the utility model are:
1. really come into the market for the LED LCD, carry out theoretical foundation.
2. can make lcd products realize that energy consumption is low, the life-span is long.
3. can make the arbitrary any adjustment of LCD realization to brightness and color; Realization is from the coloured image of black and white to any monochrome to any colour temperature.
4. can make the LED lcd products enter high-grade, precision and advanced field.
Description of drawings
Accompanying drawing is a structural principle synoptic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
With reference to the accompanying drawings, the utility model has increased the control of full spectrum module backlight and global function on the basis of conventional liquid crystal; That is to say that the utility model forms a pillar made of LED plate at interval by having different wave spectrum RGBs (R, G, B) LED luminotron, then with the full spectrum of the evenly distributed formation of pillar made of LED plate module backlight, the LED luminotron that wherein will have same wave spectrum is controlled by the same control line of display main board, such as the LED luminotron of all red wave spectrums being connected in parallel on the same control line of display main board; In like manner, LED luminotron green and blue wave spectrum divides into groups to be connected in parallel on the two other control line of display main board respectively, display main board is controlled the strength of current of the LED luminotron of each wave spectrum respectively by control module, thereby control the brightness of different wave spectrum LED luminotrons, realize the light emitting control of full spectrum; Display main board is connected with LCD through data line.Because the utility model is by the integral body control of display main board to each wave spectrum LED luminotron in the pillar made of LED plate, the chromatogram frequency range that the formation system needs offers liquid crystal display and uses; Thereby the utility model can be realized the demonstration of the arbitrary image of arbitrary hue effect.
Luminous main body in the utility model can be formed at interval for the LED luminotron of multiple wave spectrum, all LED luminotrons of each wave spectrum are connected in parallel on the same control line of display main board, therefore, persons skilled in the art can combination in any pillar made of LED plate, corresponding some control lines of employing are controlled the LED luminotron of each wave spectrum respectively, so the utility model dirigibility height, applicability is strong.
Claims (5)
1. the LCD of a LED color tunable is characterized in that comprising full spectrum module backlight, display main board and LCDs; Described full spectrum module backlight comprises some pillar made of LED plate, and each described pillar made of LED plate comprises the LED luminotron of some different wave spectrums; Wherein the LED luminotron of same wave spectrum is connected in parallel on the same control line of described display main board; Described display main board is connected with described LCD through data line.
