Abstract
The utility model discloses a display device comprising a blacklighting lamp-house (1), a LCD (3) and an additional layer which is arranged between the blacklighting lamp-house (1) and the LCD and is provided with a colorful pattern. The display device of the utility model is applicable to the household electrical products, and has the advantages of colorful screen effect on the condition that the cost is not increased.
Description
Technical field
The utility model relates to field of display devices, particularly a kind of liquid crystal indicator that the color screen effect is arranged.
Background technology
Along with the raising of people's quality of life, all can be equiped with liquid crystal indicator usually in the household appliances, only consider usually in demonstration that at present the color of the light emitting diode of change backlight changes the effect of demonstration, its demonstration is very dull.Thereby part producer adopts the color screen display device to replace LCD, but existing color screen display device price is very expensive, and it can't be popularized at cost increasingly competitive today, can't satisfy user's demand.
The utility model content
The technical problems to be solved in the utility model is, the liquid crystal indicator that a kind of cost is low, the color screen effect is arranged is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of display device, comprise LCDs, backlight and be arranged on described LCDs and described backlight between have the extra play of color screen pattern.
Display device of the present utility model is characterized in that, described extra play is a light transmission medium colored or black and white.
Display device of the present utility model is characterized in that, described light transmission medium is fixed on the lower surface of described LCDs.
Display device of the present utility model is characterized in that, described light transmission medium is fixed on the upper surface of described backlight.
Display device of the present utility model is characterized in that, described light transmission medium is arranged between described LCDs and the described backlight replaceably.
Display device of the present utility model is characterized in that, described extra play is for being imprinted on the color screen pattern by ink-jet technology the patterned layer of described LCDs lower surface or backlight upper surface.
Display device of the present utility model is characterized in that, described backlight is light emitting diode or electroluminescent source.
Display device of the present utility model is characterized in that, described display device also comprises the driving circuit of lighting backlight and LCDs.
Display device of the present utility model is characterized in that, described display device is installed in the housing.
Display device of the present utility model is characterized in that, described backlight is the light source of white.
Compared with prior art, the utility model display device is provided with the extra play of color screen pattern between backlight and LCD, have the advantage that is issued to the color screen effect in the prerequisite that does not increase too much cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model display device is described further, in the accompanying drawing:
Fig. 1 is the synoptic diagram of the utility model display device first embodiment.
Fig. 2, Fig. 3 and Fig. 4 are the structural representations of the utility model display device first embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model display device is described in further detail.Fig. 1 is the synoptic diagram of the utility model display device first embodiment.Described display device can be installed in the housing 10, comprises backlight 1, LCDs 3, and is arranged on the extra play that has the color screen pattern between described LCDs 3 and the described backlight 1.
The described extra play of present embodiment is the light transmission medium 2 that one deck has the color screen pattern, and described light transmission medium 2 can be hinge, transparent film paper or the like; The color screen pattern of described light transmission medium 2 makes described display device have the color screen effect.Described light transmission medium 2 can be solidificated in the lower surface of described LCDs 3, as shown in Figure 2; Also can be solidificated in the upper surface of described backlight 1, as shown in Figure 3; Can also be located at replaceably between described LCDs 3 and the described backlight 1, as shown in Figure 4.
Described display device can also comprise driving circuit, and described driving circuit is used to light described backlight 1 and LCDs 3.Described backlight 1 is light emitting diode (LED) or electroluminescent source (EL, Electro Luminescence), lights luminous by described driving circuit.
When described display device is worked, light the light emitting diode of backlight 1 or the displaying contents of electroluminescent source and display device by driving circuit by lighting circuit, illuminate light transmission medium 2 simultaneously, demonstrate the color screen pattern, thereby make the displaying contents of display device under the background of color screen pattern, show, have the effect that color screen shows.LCDs is the full-transparency type LCDs, and when background light source was lighted, pattern directly was presented on the liquid crystal display, when background light source does not work, though brightness is not high, also can sees through liquid crystal display and see background patterns.Because background patterns is positioned at the below of liquid crystal display, does not influence the former meaningful demonstration of liquid crystal.For guaranteeing the true of display color, the bias light source plate adopts white background illuminating source.
The extra play of another embodiment of the utility model display device is by ink-jet technology the color screen pattern to be reflected patterned layer at the lower surface of backlight 1 upper surface or LCDs 3.Can make the displaying contents of display device under the background of color screen pattern, show by the bright described patterned layer of illumination of backlight 1 light emitting diode or electroluminescent source equally, have the effect that color screen shows.
