Abstract
A combined liquid crystal display comprises a black and white liquid crystal display and a color TFT liquid crystal module, wherein the color TFT liquid crystal module is arranged on the back of the black and white liquid crystal display, the polarization axis of a back polarizer of the black and white liquid crystal display is parallel to the polarization axis 5 of a front polarizer of the color TFT liquid crystal module, and the middle of the black and white liquid crystal display is provided with a light valve with the same size as the display area of the color TFT liquid crystal module. The utility model adds the color TFT liquid crystal module to match and use on the basis of the black and white liquid crystal display, thereby greatly enriching the display content; the cost of the whole scheme of the combination instrument is greatly reduced compared with that of the scheme of the full-liquid crystal color instrument, but the overall display content, the diversity of the display colors and the appearance integrity are not obviously deteriorated compared with the scheme of the full-liquid crystal color instrument. The scheme of the large-size black and white liquid crystal display and color TFT liquid crystal module combined instrument can well solve the problems of display singleness of a vehicle-mounted black and white liquid crystal display and high price of a large-size full liquid crystal color instrument.
Description
Technical Field
The utility model relates to an on-vehicle demonstration technical field.
Background
The conventional black-white liquid crystal display can only realize monochrome display, the display effect is monotonous, and if a large-size color liquid crystal display is adopted, the mold opening cost and the manufacturing cost are very high. The design of the large-size black and white liquid crystal display and color TFT liquid crystal module combined instrument not only can enable the black and white liquid crystal display to display colors, but also can solve the problem that the large-size color liquid crystal display is expensive.
At present, the vehicle-mounted instrument tends to be changed from a mechanical instrument to a full liquid crystal instrument. However, if a large-sized full liquid crystal color instrument is adopted, the price is very expensive, and if a large-sized black and white liquid crystal display is adopted as a vehicle-mounted instrument, the display effect is single, and complicated color contents cannot be displayed.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned problem that current on-vehicle instrument exists, the utility model provides a combination LCD.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: a combined liquid crystal display comprises a black and white liquid crystal display and a color TFT liquid crystal module, wherein the color TFT liquid crystal module is arranged on the back of the black and white liquid crystal display, the polarization axis of a back polarizer of the black and white liquid crystal display is parallel to the polarization axis 5 of a front polarizer of the color TFT liquid crystal module, and the middle of the black and white liquid crystal display is provided with a light valve with the same size as the display area of the color TFT liquid crystal module.
The black-white liquid crystal display is manufactured in a VA black film mode.
The combined liquid crystal display of the utility model adds the color TFT liquid crystal module to match and use on the basis of the black and white liquid crystal display, thereby greatly enriching the display content; the cost of the whole scheme of the combination instrument is greatly reduced compared with that of the scheme of the full-liquid crystal color instrument, but the overall display content, the diversity of the display colors and the appearance integrity are not obviously deteriorated compared with the scheme of the full-liquid crystal color instrument. The scheme of the large-size black and white liquid crystal display and color TFT liquid crystal module combined instrument can well solve the problems of display singleness of a vehicle-mounted black and white liquid crystal display and high price of a large-size full liquid crystal color instrument.

Fig. 2 is a front view structure diagram of the combined liquid crystal display of the present invention.
In the figure: 1. black and white liquid crystal display, 2, black and white liquid crystal display rear polarizer, 3, color TFT liquid crystal module, 4, polarizing axis of polarizer, 5, polarizing axis of front polarizer, 6, light valve.
Detailed Description
The utility model discloses a combination LCD structure is shown in fig. 1 and fig. 2, adopts jumbo size black and white LCD 1 and colored TFT LCD module 3 combination meter, and jumbo size black and white LCD 1 is in the front during the combination, and colored TFT LCD module 3 is after, counterpoint collocation combination, and simultaneously jumbo size black and white LCD 1 back polaroid polarization axis 4 keeps parallel with colored TFT LCD module 3's preceding polaroid polarization axis 5. The large-size black and white liquid crystal display 1 is manufactured by a VA black film mode, a light valve 6 with the same size as the display area of the color TFT liquid crystal module 3 is arranged in the middle of the display, and other display contents can be designed around the light valve 6. The middle light valve 6 is driven statically, so that the light transmittance during lighting can be ensured, and other display contents can be driven in a multi-path or static manner. The front black-white liquid crystal display can display black and white display contents when the combination instrument is lightened, and the middle light valve is lightened, so that the light valve only plays the role of a light switch, the contents displayed by the color liquid crystal module matched below can be displayed when the light valve is lightened, and the large-size full-liquid-crystal color instrument is integrated when the front side of the combination instrument is observed.
The color TFT liquid crystal module is added on the basis of the black and white liquid crystal display to be matched for use, so that the display content is greatly enriched. The black and white liquid crystal display can display information such as water temperature, oil quantity, alarm and the like, and the color TFT liquid crystal module matched with the lower part of the middle light valve can display complex contents such as information of a running computer, navigation information and the like. The cost of the whole scheme of the combination instrument is greatly reduced compared with that of the scheme of the full-liquid crystal color instrument, but the overall display content, the diversity of the display colors and the appearance integrity are not obviously deteriorated compared with the scheme of the full-liquid crystal color instrument. The scheme of the large-size black and white liquid crystal display and color TFT liquid crystal module combined instrument can well solve the problems of display singleness of a vehicle-mounted black and white liquid crystal display and high price of a large-size full liquid crystal color instrument.
