Description

Color monitor

The utility model relates to a kind of display, particularly a kind of color monitor with preferable colour mixture effect.

Display institute's role in information society now is the output unit of a performance picture and literal signal, and along with information product develops towards light, thin target, flat-panel screens becomes the main flow in the electronic application product gradually, such as various electrical appliances in the daily life, the application of flat-panel screens is increased.

The output of image system is made of the many pixels (Pixel) on the panel in the display, and form image with the lightness of different colors by pixel, and in the display of prior art, as shown in Figure 1, each pixel 12 is divided into three sub-pixels 14 and has red (R) separately, green (G), blue (B) three primary colors, and color drives module 10 at each sub-pixel 14 of vertically arranging and sub-pixel 14 that each is transversely arranged is respectively equipped with one group of data transmission cabling 16 (Segment) and one group of signal scans cabling 18 (Common), and each cabling 16,18 also are subjected to the driving of semiconductor driving element 20 and driving element 22 respectively, controlling the bright of each sub-pixel 14 with dark by voltage swing respectively, and and then be in harmonious proportion to scale and demonstrate the color of full color mode via three primary colors.

Right this kind is colored to drive the design of module 10 for the high color display of the high-order of resolution more than 160 * 160, though can obtain preferable image quality and colour mixture effect, but it is comparatively complicated in the design of its driving circuit, manufacture craft is difficulty comparatively, and required semiconductor driving element 20,22 numbers are numerous so cost is higher, and be not suitable for all products, and for the lower display of resolution, this kind is colored to be driven module 10 and can make serious zigzag or the brick-shaped problem of generation in the demonstration of image and literal, and the colour mixture effect is restricted, and causes not good display effect.Therefore the utility model ties up to according to above-mentioned puzzlement, and proposes a kind of color monitor.

Fundamental purpose of the present utility model system proposes a kind of by the zone that the sub-pixel in each pixel is divided into several tool different colors so that display frame is more careful, and have preferable colour mixture effect and display effect suitable with the high-order display.

Another purpose of the present utility model system proposes a kind of low price color monitor that improves zigzag in the display frame or brick-shaped problem.

A purpose more of the present utility model ties up to provides a kind of low order color monitor, with under the condition of continuing to use original manufacture craft and equipment, makes display have the display effect of high image quality.

According to the utility model, panel in the color monitor has the pixel of marshalling, each pixel comprises at least two group sub-pixels, and each sub-pixel also is made up of at least two kinds of colors, and each transversely arranged sub-pixel system scans the cabling electric connection by a signal, and the color that each is vertically arranged also utilizes data transmission cabling to electrically connect, wherein at least two row in each pixel of vertically arranging connect the data transmission cabling of same hue, and link together by an electric conduction routing, so that these at least two data transmission cablings are connected to identical driving element.

Color monitor of the present utility model has the suitable effect of colour demonstration with the high-order display, and can avoid zigzag or brick-shaped problem in the display frame; In addition, making of the present utility model is original manufacture craft and the equipment continued to use, and driving element drives the design of at least two data transmission cabling simultaneously, not only can reduce color drives the degree of difficulty in the module making and has controlled preferable advantage, more can reduce the number of driving element, make the characteristic of the utility model with high image quality and low price.
