Description
Technical field
The invention relates to a kind of adjustment circuit and method of adjustment, particularly relevant for a kind of adjustment circuit and method of adjustment thereof of color-sequence liquid crystal display (LCD) device.
Background technology
Scientific and technological now flourish, the information product kind is weeded out the old and bring forth the new, and has satisfied popular different demand.Because liquid crystal display (Liquid Crystal Display, LCD) have advantages such as compact, low radiation dose and low power consumption, and conventional display apparatus has big, high power consumption of volume and high radiation dose, therefore, therefore display device on the market will replace conventional display apparatus by liquid crystal display gradually now, and also liquid crystal display becomes the main flow in present display device market.In order to make liquid crystal display reach several big characteristics of maximization, colorize and slim, light weight, low electric power loss, in the design of liquid crystal display, just must develop high performance light source now.
Because liquid crystal display self can be not luminous, therefore the bad place of light Like attitude outside just must use the mode Come of illumination luminous.For example, the liquid crystal display of wrist-watch uses simple miniature bulb as illumination; Employed liquid crystal displays such as vapour Trucks ammeter or OA terminating machine also are luminous by the lighting source at rear, just can obtain distinct demonstration.These use low profile light source to be called (Back Light) backlight overleaf.Traditional liquid crystal display utilizes colored filter to filter light source, makes single picture element show trichromatic composition simultaneously, to demonstrate the color of this picture element.A picture element of the liquid crystal display of this kind tool colored filter is combined by three sub-picture elements, to correspond to red, the green and blue color filter of colored filter respectively.Human eye receives light source shown red, green and blue light that goes out after by colored filter, can with mixing and experience the color of this picture element, but the colorized optical filtering sector-meeting influences the light transmittance of liquid crystal display integral body, and colored filter also influences display dot (dot) size of the single picture element of liquid crystal display, causes the resolution of liquid crystal display to be subjected to the restriction of colored filter.
A kind of look preface formula (Color Sequential) liquid crystal display in order to improve problems such as above-mentioned resolution and light transmittance, to develop then now.Color-sequence liquid crystal display (LCD) device shows three former colour contents of a picture element successively and presents color.Each picture element of this kind color-sequence liquid crystal display (LCD) device is by by three light emitting sources, send red, green respectively and blue light with as backlight.In time, this picture element is according to video data, and red, the green and blue light of corresponding respectively unlatching at a picture frame.Utilize the persistence of vision of human eye, the people can pick out the color of this picture element.Therefore, color-sequence liquid crystal display (LCD) device need not be provided with colored filter, and the size of each picture element of therefore planting color-sequence liquid crystal display (LCD) device is less than each picture element of the liquid crystal display of tool colored filter, so color-sequence liquid crystal display (LCD) device can reduce cost, and can improve resolution.
The color-sequence liquid crystal display (LCD) device that prior art is used has only and utilizes red R, green G, the trichromatic luminescence unit of blue B is as backlight, for example: light emitting diode (LED), with by constitute the color that single picture element can show by the three primary colors backlight, but the three primary colors backlight generally can only be formed 8 kinds of basic colors, therefore only can show 8 kinds of basic colors on the single picture element, so the color-sequence liquid crystal display (LCD) device that prior art is used is obviously dull in the use of color, and the color-sequence liquid crystal display (LCD) device that prior art is used see through to use look preface method and during show image, the brightness of image is obviously not enough, so promptly can reduce the quality of color-sequence liquid crystal display (LCD) device display color image.
Therefore, how propose a kind of adjustment circuit and method of adjustment thereof of color-sequence liquid crystal display (LCD) device, can improve the shortcoming of the display color dullness of traditional colour sequence liquid crystal display (LCD) device, solving the above problems at the problems referred to above.
