Fig. 2 is the structural representation of rotary mode liquid crystal indicator first embodiment in the utility model plane.The utility model liquid crystal indicator 2 comprises that infrabasal plate 211, that a upper substrate 210, one and this upper substrate 210 are oppositely arranged is clipped in the liquid crystal layer 230 between this two substrates 210,211.Be sequentially provided with both alignment layers 240 on a colored filter 250 and on these upper substrate 210 inner surfaces, polaroid 220 on these upper substrate 210 arranged outside one.These infrabasal plate 211 inner surfaces are provided with public electrode 212, an insulation course 260, pixel electrode 213, a semi-reflective layer 217 and both alignment layers 241 once, wherein this public electrode 212 and this pixel electrode 213 are parallel interval settings, can be vertical bar shape or curve list structure.These infrabasal plate 211 arranged outside are polaroid 221 once.Wherein, this liquid crystal layer 230 comprises a plurality of liquid crystal molecules, this insulation course 260 is to adopt the transparent insulation material, make this public electrode 212 and pixel electrode 213 keep this public electrode 212 of electric insulation and pixel electrode 213 to adopt transparent conductive material to make, as tin indium oxide (Indium Tin Oxide, ITO) or indium zinc oxide (Indium Zinc Oxide, IZO) etc.This pixel electrode 213 is transparency electrodes, is arranged alternately with these public electrode 212 levels.When applying a driving voltage, can produce an electric field that is parallel to infrabasal plate 211 between this public electrode 212 and the pixel electrode 213, this electric field can make the liquid crystal molecule of liquid crystal layer 230 rotate in the plane that is parallel to infrabasal plate 211.
This semi-reflective layer 217 is positioned at infrabasal plate 211 inboards, it is reflector space 2171 and penetration region 2172 that this semi-reflective layer 217 contains two zones, when 2 work of rotary mode liquid crystal indicator in this plane, the light beam irradiates of launching from module backlight (figure do not show) is to this semi-reflective layer 217 time, the light beam that shines on this semi-reflective layer 217 is partly passed through, for demonstration provides a light source; When external environment light (figure do not show) when shining on this semi-reflective layer 217, can reflect at this semi-reflective layer 217, light beam can be reflected back toward this liquid crystal layer 230, for demonstration provides another light source.This two light source can jointly or separately for rotary mode liquid crystal indicator 2 in this plane provides illumination, realization shows.This reflector space 2171 is that the dielectric material by high reflectance piles up and forms, and this penetration region 2172 is that the dielectric material by high penetration piles up and forms.
Please together consult Fig. 3, this colored filter 250 comprises a black matrix" 252, a dyed layer 253 and a protective clear layer 254.This dyed layer 253 has red (R), green (G), blue (B) three kinds of coloring units.This black matrix" 252 is arranged between this three coloring units; its effect is that blocking is by the light between three coloring units; prevent leakage of light and stop coloured material to mix; protective clear layer 254 covers on black matrix" 252 and the dyed layer 253, is used to protect this black matrix" 252 and dyed layer 253.These colored filter 250 each coloring units are divided into A of first and second portion B by itself and semi-reflective layer 217 corresponding relations; wherein corresponding with reflector space 2171 part is the A of first; the part corresponding with penetration region 2172 is second portion B; wherein on the A of this first a plurality of apertures 255 are set; this aperture 255 is the non-staining part; filled by protective clear layer 254, the coloured part area of the A of this first equates with aperture 225 areas.
During ambient light incident, it penetrates colored filter 250 A of first, through the reflector space reflection, penetrate outgoing behind the A of first once more, module light backlight is through penetration region 2172, penetrate outgoing behind the colored filter 250 second portion B, therefore ambient light is module light backlight twices through the light path of colored filter 250 through the light path of colored filter 250, because the A of first is provided with aperture 255, coloured part 253 areas of the A of this first are half of the A of this first area, therefore ambient light penetrate the painted total amount of coloured part 253 and module light penetration coloured part 253 backlight painted total amount about equally, all emergent raies can obtain roughly the same color saturation; Therefore rotary mode liquid crystal indicator 100 demonstration briliancy and contrast is all higher and color saturations all emergent raies are roughly the same in this plane are to guarantee its good display quality.
Please together consulting Fig. 4 again, is the colorful filter structure synoptic diagram of rotary mode liquid crystal indicator second embodiment in the utility model plane.This colored filter 250 ' comprise equally transparent substrates 251, a black matrix" 252 ', a dyed layer a 253 ' and protective clear layer 254 ', itself and colored filter 250 differences are: the second portion B ' thickness in each coloring units is the twice of first's A ' thickness.When liquid crystal indicator 2 was realized showing, ambient light needed secondary through the A ' of first, and module light backlight is as long as once pass through second portion B ', so the painted total amount that all emergent raies penetrate coloured part about equally, and its color saturation is also consistent.
Seeing also Fig. 5, is the colorful filter structure synoptic diagram of rotary mode liquid crystal indicator the 3rd embodiment in the utility model plane." thickness is identical, make outgoing light color saturation degree unanimity, and second portion B " colour saturation and be about the A of first " twice of colour saturation, and its structure is more simple for thickness and the A of first for this colored filter 250 " second portion B ".
Seeing also Fig. 6, is the structural representation of rotary mode liquid crystal indicator the 4th embodiment in the utility model plane.In this plane in rotary mode liquid crystal indicator 3 and the plane difference of rotary mode liquid crystal indicator 2 be: this semi-reflective layer 317 is to be piled up by multilayer dielectric material to form between infrabasal plate 311 and following polaroid 321.When rotary mode liquid crystal indicator in this plane 3 work, the light beam irradiates of launching from module backlight (figure does not show) can make the light beam that shines on this semi-reflective layer 317 partly pass through, for demonstration provides a light source to this semi-reflective layer 317 time; When external environment light (figure do not show) when shining on this semi-reflective layer 317, can reflect at this semi-reflective layer 317, light beam can be reflected back toward this liquid crystal layer 330, for demonstration provides another light source.This two light source can jointly or separately for rotary mode liquid crystal indicator 3 in this plane provides illumination, realization shows.Equally, in this plane, in the rotary mode liquid crystal indicator 3, a plurality of apertures 355 are set on the A of first of colored filter 350.Certainly, colored filter 350 second portion thickness B also can be the twice of the A of first thickness, and perhaps colour saturation be the twice that first colour saturation to second portion.
