Abstract
The utility model provides a stroke segment type color liquid crystal display (LCD) comprising a negative black-and-white display screen and a backlight unit used for supplying light source for display of the negative black-and-white display screen, wherein a region color filter layer is arranged on the backlight unit; the light source penetrates through the region color filter layer so as to form backlight of different colors. In the stroke segment type color LCD, white point light sources pass through the backlight unit to reach the stroke segment type color LCD; after the white point light sources pass through the backlight unit with the region color filter layer, different colors can be formed in different regions, therefore, patterns which are matched with the light and are displayed by the negative black-and-white display screen can show corresponding colors, so that colorization is formed. The stroke segment type color LCD can be realized without matching of a special drive IC (integrated circuit) and a three-color LED (light-emitting diode) lamp, therefore, the cost of the method is relatively low.

Embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to shown in Fig. 1-3, a kind of segmentation colour liquid crystal display device, comprise negativity white and black displays screen 1 and be used to provide the back light unit 2 of light source for the demonstration of negativity white and black displays screen, described back light unit 2 is provided with regional chromatic filter layer, this chromatic filter layer zones of different is formed with the filter coating of different colours, described light source forms the backlight of different colours by behind the regional chromatic filter layer.
The segmentation colour liquid crystal display device that the utility model provides, arrive a segmentation colour liquid crystal display device by the white point light source through back light unit, the white point light source is by after the back light unit of region chromatic filter layer, formed the light of different colours in zones of different, therefore the negativity white and black displays screen display pattern that is complementary with it just can show corresponding color, to form colorize.The utility model does not need special-purpose drive IC and three-color LED light to cooperate realization, so the method cost is lower.
Described back light unit 2 comprises reflectance coating 21, light guide plate 22, diffusion sheet 23, time bright enhancement film 24, last bright enhancement film 25 and the shading glue 26 of sequential cascade, described shading glue 26 is located at the negativity white and black displays and is shielded 1 below, is provided with regional chromatic filter layer on any film material between light guide plate 22 and the negativity white and black displays screen 1.Be that described regional chromatic filter layer can be arranged on diffusion sheet 23, following bright enhancement film 24, go up on any one the film material in bright enhancement film 25 and the shading glue 26, the purpose of She Zhiing is to consider that different colours in the chromatic filter layer has the complicacy of offset and technology between adjacent like this, through inventor's research, be produced on the aforementioned several film materials proper.
Preferably, described regional chromatic filter layer is located on the bright enhancement film material, can at utmost reduce the damage to the film material like this.The method that the zone chromatic filter layer is located on the bright enhancement film material has no particular limits, as long as can effectively be formed at the bright enhancement film material.Particularly, described regional chromatic filter layer adopts the mode of printing to be produced on the bright enhancement film, and perhaps described regional chromatic filter layer adopts the mode of coating to be produced on the bright enhancement film.Further, the pattern that the described regional chromatic filter layer area of going up on the bright enhancement film is gone up each viewing area than negativity white and black displays screen is big, because a segmentation LCDs has many places that do not show, therefore can chromatic filter layer make than needs show local big, can effectively reduce the precision of chromatic filter layer and display pattern contraposition like this.
The color of the filter coating of zones of different has no particular limits in the described regional chromatic filter layer, can make according to actual needs, as field of liquid crystal display mode commonly used, described regional chromatic filter layer comprises redness, green and blue three filter coating zones.Certainly, filter coating also can be other color in the described regional chromatic filter layer, such as being redness, yellow and three filter coating zones of purple.As a kind of concrete embodiment, please refer to shown in Figure 3, the segmentation colour liquid crystal display device implementation result figure that accompanying drawing 3 provides for the utility model embodiment.Particularly, the described regional chromatic filter layer of going up on the bright enhancement film 25 is divided into three zones 251,252 and 253, in 251,252 and 253 3 zones, make the colour filter film of redness, yellow and purple respectively, 1 pair of negativity white and black displays screen should have three viewing areas 11,12 and 13, when the negativity white and black displays is shielded 1 display pattern, 11 zones be red font, 12 zones be yellow font, 13 zones be the purple font, other places are black.The entire display screen curtain is a black when not showing, can not see the color of colour filter film in the chromatic filter layer, this is because the white and black displays screen shows for negativity, guaranteed that the white and black displays screen is enough black when not showing, color filter film all can not be seen in the place of display pattern and non-pattern displaying, has guaranteed the background color consistance.
Described negativity white and black displays screen 1 comprises first transparency carrier 11 and second transparency carrier 12 that is oppositely arranged, the inside surface of described first transparency carrier is provided with first oriented layer 16, the inside surface of described second transparency carrier is provided with second oriented layer 17, the circumferential edges of described first transparency carrier and the second transparency carrier inside surface is provided with frame adhesive 15, described first oriented layer, second oriented layer and frame adhesive surround a cavity, accommodate liquid crystal 18 in the described cavity, described liquid crystal can be selected the liquid crystal of negative material for use; Further, the outside surface of first transparency carrier 11 outside surface that is provided with first polaroid, 13, the second transparency carriers 12 is provided with second polaroid 14.Preferably, described first oriented layer and second oriented layer are the vertical orientation layer, when adopting the vertical orientation material to make to be made into negativity white and black displays screen not show, can't see background color.
The segmentation colour liquid crystal display device that the utility model provides, its principle of work is exactly that white light source is through behind the filter coating, the filter coating of zones of different forms the light of different colours, cooperates negativity white and black displays screen to hide the character that saturating characteristic forms different colours simultaneously, forms colorize.Adopt the LCD of this structure to have the low-cost colorize of realizing, reach good effect in some applications, described application can be that other requirement of refrigerator, air-conditioning, electric cooker or the like is not very high field.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
