Abstract: An LCD includes a display module and a backlight module arranged below the displaying module. The displaying module includes an upper and lower transparent substrates, a liquid crystal layer formed between the upper and lower transparent substrates, a translucent reflecting layer formed between the liquid crystal layer and the lower transparent substrate, and an anti-reflection coating formed between the translucent reflecting layer and the lower transparent substrate. The backlight module is adjacent to the lower transparent substrate. Therefore, a first transmission rate of an inner light that passes from the backlight module to the displaying module is increased, and a luminance of the liquid crystal display is improved.

Abstract: The present invention provides a multi-color LCD device comprises two liquid crystal panels stacked up and down. A first polarizer, a second polarizer, and a third polarizer or a reflector are disposed above, between, and below these two liquid crystal panels, respectively. Each of the polarizers has a transmission axis and an absorption axis orthogonal to each other. The transmission axis of each of the polarizers lets white light be transmitted. The absorption axes of the first and second polarizers absorb lights of complementary colors. The absorption axis of the third polarizer absorbs white light. Through whether applying voltages onto the two liquid crystal panels or not, different color displaying effects can be achieved. The present invention has the advantage of low cost.

Abstract: The present invention provides a multi-color liquid crystal display, wherein polarizing plates are disposed above, below, and between at least two liquid crystal displaying modules stacked up and down. The polarizing plates can be combinations of polarizing plates absorbing monochromatic light and general uncolored polarizing plates. Various kinds of colors can be achieved according to whether a voltage is applied onto the liquid crystal displaying modules. The present invention has a low price to apply to some portable products requiring less number of colors.

Abstract: The present invention provides a color display comprising a plurality of pixels. Each of the pixels comprises at least two sub-pixels, each being composed of at least two colors. At least two data transmission lines of the same color in each line of the longitudinally-arranged pixels are joined together by a conductive line to be connected to the same driving part and simultaneously controlled. The present invention can let a display of lower resolution have better color mixing effect to obtain displaying effect commensurate with that of a high-level display. Moreover, the problem of zigzagged or brick-shaped pictures can be improved.

Abstract: The present invention proposes a color display utilizing combinations of four colors, wherein full-color images are obtained by controlling gray-scale contrast of a plurality of pixels each having four colors. The four colors are two primary colors and two contrastive colors complementary to them, e.g., the red and its complementary color—cyan and the green and its complementary color—magenta. The present invention can enhance the color fullness and the delicacy of images without increasing the cost and changing the design of structure.

Abstract: The present invention provides a panel driving module, wherein a panel is formed by alternately arranging a plurality of pixels each composed of two sub-pixels. The two sub-pixels are a primary color and its complementary color. The sub-pixels of the primary color and the sub-pixels of its complementary color are alternately arranged. Each row of sub-pixels and each column of sub-pixels are connected together through a signal scan line and a data transmission line, respectively. Every two alternate lines are joined together to form a group and then connected to a driving part. A wire or a conductive spacer is used to connect the two alternate lines in each group. The present invention can decrease the count of semiconductor driving parts used and reduce the cost.

Abstract: The present invention provides a color display utilizing two complementary colors arranged in checker form. The color display comprises a plurality of pixels. Each pixel is composed of a kind of color. Multi-color displaying effect is achieved through combination and variation of brightness and gray-scale contrast of the pixels. The color is selected from a primary color and its complementary contrastive color, e.g., a primary color of red and its complementary color of cyan. The pixels of the primary color and its complementary color are alternately arranged in checker form. The present invention uses the same number of driving components as a convention monochromatic display, and has multi-color displaying function. The present invention has the advantages of a simple structure, easy manufacture, and a low cost.
