Description
[technical field]
The present invention relates to a kind of liquid crystal indicator, particularly relate to a kind of color liquid crystal display arrangement.
[background technology]
Lcd technology has obtained very great development in recent years, and liquid crystal indicator has progressively replaced heavy CRT display device.The frivolous energy-conservation of electronic installation is social now universal demand, therefore makes more frivolous, the more power saving of display device, is the direction that manufacturer constantly makes great efforts.Current, use the light source of light emitting diode as liquid crystal indicator, replace cathode fluorescent tube, be an approach that makes frivolous energy-conservationization of liquid crystal indicator.Fig. 1 illustrates the schematic top plan view of a kind of color liquid crystal display arrangement of prior art; Fig. 2 illustrates the diagrammatic cross-section of facing of a kind of color liquid crystal display arrangement of prior art.Color liquid crystal display arrangement 10 as depicted in figs. 1 and 2 comprises display panels and backlight.Described backlight comprises white light source 182 (for example being white light emitting diode or cathode fluorescent tube) and light guide plate 181.The light 191 that white light source 182 sends becomes more uniform white area source 192 after light guide plate 181, invest display panels.Display panels comprises: the liquid crystal cell that is made of substrate 12, substrate 17 and liquid crystal layer 15; Be positioned at first polaroid 111 in substrate 12 outsides; Be positioned at second polaroid 112 in substrate 17 outsides; Be positioned on the substrate 12 and be positioned at a plurality of red colour filter block 131 of liquid crystal cell inboard, a plurality of green colour filter block 132 and a plurality of blue colour filter block 133.Display panels can also comprise common electrode 141 and the pixel electrode 142 that is separately positioned on substrate 12 and the substrate 17, so that liquid crystal is driven.White area source 192 filters through red colour filter block 131, green colour filter block 132 and blue colour filter block 133 respectively becomes red light 193, green light 194 and blue light 195, this three coloured light and then form various colors.
The principle of luminosity of at present the most frequently used white light emitting diode sends blue light for adopting semiconductor electronic and hole-recombination, be mixed with yellow fluorescent powder in the light emitting diode, the blue-light excited yellow fluorescent powder of part sends sodium yellow, and sodium yellow and the mixing of non-switched blue light obtain white light.Because hole and the compound of electronics can generate heat simultaneously, temperature raises and causes fluorescence radiation efficient to reduce, and the chromaticity coordinates of white light also can be changed.
In addition, the colour filter block in the display panels absorbs unwanted color in the white light, only allows corresponding red, green or blue light pass through, and can reduce the utilization factor of light like this.
