Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
A TFT module with an energy-saving reflection display function comprises a TFT liquid crystal box 4, a VA type monochromatic pen section liquid crystal box 2, an upper polarizer 1, a lower polarizer 5 and a backlight 6.
The VA type monochromatic pen section liquid crystal box 2 is directly attached to the upper surface of the TFT liquid crystal box 4 through the optical cement 3, and the visual angles of the VA type monochromatic pen section liquid crystal box 2 and the TFT liquid crystal box 4 are kept opposite; when the two liquid crystal boxes are jointed, the TFT liquid crystal box 4 needs to be provided with an aluminum film upwards. This is because the monochrome pen-segment liquid crystal cell 2 requires a reflective layer underneath it to act as a reflector.
The upper surface of the VA type monochromatic pen section liquid crystal box 2 is attached with a polarizer 1, and the lower surface of the TFT liquid crystal box 4 is attached with a lower polarizer 5; the upper polarizer 1 and the lower polarizer 5 are both polarizers matched with the TFT liquid crystal box 4. Finally, the two bonded liquid crystal cells are assembled on a backlight 6.
When the VA type monochromatic pen section liquid crystal box 2 is a reflective-mode front display, the TFT liquid crystal box 4 is a TN type TFT liquid crystal box.
When the VA type monochromatic pen section liquid crystal box 2 is in a reflective mode, the TFT liquid crystal box 4 is a VA type TFT liquid crystal box.
Firstly, when the monochromatic pen-segment type liquid crystal box 2 is a TFT module in the positive display:
1) the front is a monochromatic pen-section type liquid crystal box 2, and the original matched polaroid (upper polaroid 1) of the TFT liquid crystal box 4 is attached to the front of the liquid crystal box, and the angle is the same as that before.
2) The rear piece of the monochromatic pen-section type liquid crystal box 2 is not adhered with a polaroid, and is directly adhered to the TF liquid crystal box 4 by using optical cement, so that the visual angles of the two liquid crystal boxes are kept opposite in visual angle.
3) The front of the TFT liquid crystal box 4 is directly jointed with the monochromatic pen-section type liquid crystal box 2 without being jointed with a polaroid.
4) During the attaching, the TFT liquid crystal box 4 is attached to the monochromatic pen-section type liquid crystal box 2 with the aluminum film facing upwards; contrary to the usual way of using TFT liquid crystal cells 4.
5) The non-aluminum film side of the TFT liquid crystal box 4 is pasted with a polarizer 5 in the original mode. Behind the lower polarizer 5 is a backlight 6.
When the monochromatic pen-section type liquid crystal box 2 is a TFT module for negative display:
the structure is basically the same as that of the front display, the TN type TFT liquid crystal box is only required to be changed into the VA type TFT liquid crystal box, the two attached polaroids are also required to be changed into the polaroids of the VA type TFT liquid crystal box, and the angle of the paster is consistent with that of the original paster on the VA type TFT liquid crystal box. The rest is the same.
The utility model discloses the special display effect that can realize does:
1) when the TFT liquid crystal box 4 works, the display effect is the same as that of the single TFT liquid crystal box 4, and the single-color pen-segment type liquid crystal box 2 has no influence on the single-color pen-segment type liquid crystal box
2) When the TFT liquid crystal box 4 and the backlight are closed and the single-color pen section type liquid crystal box 2 works, the reflective display of black matrix white characters or white matrix black characters is realized.
The above embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation and specific operation processes are given, but the protection scope of the present invention is not limited to the above embodiments.
