Description
Technical field
The invention relates to a kind of display drive method, and particularly come the driving method of driving display relevant for a kind of collocation look preface method (Color Sequential Method).
Background technology
Along with photoelectricity and development of semiconductor, driven the flourish of flat-panel screens, and in many flat-panel screens, LCD is because of having advantageous characteristic such as high spatial utilization ratio, low consumpting power, radiationless and low electromagnetic interference (EMI), and become the main flow in market.Wherein, LCD comprises a display panels and a module backlight.Because display panels itself do not have luminous function, therefore dispose module backlight providing display panels required area source, and then make display panels reach the function of demonstration.
The light source design of existing its module backlight of conventional liquid crystal is a white light source, and this white light source can see through colored filter (color filter) and form the required backlight of pixel each time.From a pel array, redness (R), green (G) and blue (B) three colored filters can be set on the location of pixels, this method not only expends cost, and the adjacent between red (R), green (G) and blue (B) three colored filters also has the problem existence of colour mixture.If be separated by with blue (B) three colored filters black matrix" (black matrix) of sentencing adjacent one another are at red (R), green (G),, cause the colored filter transmittance more more to descend also though can reduce the problem of colour mixture.
Based on above-mentioned problem, thereby develop the display Driving technique that to utilize control circuit collocation look preface method.This kind Driving technique is to utilize light emitting diode (light-emitting diodes LED) replaces the backlight of conventional white light to show the color of each pixel.This technology is at colour mixture on the spatial axes (red (R), green (G) and blue (B) three sub-pixels colour mixture in less than the scope at human eye visual angle on the spatial axes) with colored filter, change into via the colour mixture of back light source in LED on time shaft (in the time range that human eye vision persists, red (R), green (G) switch on time shaft fast with blue (B) three kinds of color images, produce the colour mixture effect).Therefore, this display technique need not be provided with colored filter, and then promotes the transmittance that pixel shows.
Though the display Driving technique of collocation look preface method can promote the transmittance that pixel shows, effectively improves the defective of the display that uses colored filter, this technology still can derive other problems, for example this rainbow phenomena (color breakup, CBU).Since human eye jump the instinct look or follow the trail of object in the picture at random, can make that object causes the phenomenon of object edge generation color-separated visually because the colour field of each color does not fall within the retina same point in the picture, this is rainbow phenomena.
Figure 1A illustrates the synoptic diagram that produces into rainbow phenomena.With reference to Fig. 1, in the procedure for displaying that utilizes look preface method, existing Driving technique is divided into the subframe of three kinds of colors with a full-color picture, and by showing red (R), green (G) and blueness (B) subframe, the demonstration of reaching image apace successively.Is example at this with display white (W) image, when requiring to manifest white image, the white image of seeing from mobile observation point 110, its left side edge is respectively the color scheme that blue (B) and blueness add green (B+G), its right side edge then is respectively the color scheme that red (R) and redness add green (R+G), and neither is the white (W) that manifest.
Therefore, also arise at the certain methods of improving rainbow phenomena.For example, No. the 494686th, TaiWan, China patent application case, it is to utilize the mode of motion compensation to come a full-color picture is carried out image processing and dynamic compensation, and eliminates rainbow phenomena by the move mode of prediction object.Other has a method, flow for displaying as the existing Driving technique that Figure 1B illustrated, it is to insert complete black picture between color sequence, just after red (R), green (G) and blue (B) subframe, increase by a black subframe, become red, green, blue, deceive in regular turn that the round-robin mode alleviates color-separated.A kind of method is more arranged, the flow for displaying of another the existing Driving technique that is illustrated as Fig. 1 C, it is to utilize the mode of upsetting color sequence to alleviate the effect of human eye.For example, first full-color picture F1 is made of in regular turn red (R), green (G), blue (B) three subframes, and second full-color picture F2 but becomes blueness (B), red (R), green (G) three subframes and form in regular turn.
Yet above-mentioned these lower the display Driving technique of rainbow phenomena, still have its weak point.For the technology of utilizing the motion compensation mode, it need do extra image processing and dynamic compensation, and is to be difficult for prediction for the mobile reality of object.And insert the black subframe or upset the method for color sequence, the object of its processing all is a whole image, still belongs to limited for the perception that alleviates the human eye color-separated.
