Description of the Invention: [Technical Field] The present invention relates to a control method, and more particularly to a method for controlling a color field switching frequency of a color sequential display. [Prior Art] With the evolution of optoelectronics and semiconductor technology, the flat panel display has also been vigorously developed. Among many flat panel displays, liquid crystal display (LCD) has high space utilization efficiency. The superior characteristics of low power consumption, no radiation and low electromagnetic interference have become the mainstream of the market. According to the color display mode of the liquid crystal display, it is roughly divided into two types: temporal color mixing and spatial color mixing (also called juxtaposition addition or simultaneous addition). Most commonly used displays are spatially juxtaposed and additive. Taking Thin-Film Transistor Liquid Crystal Display (TFT-LCD) as an example, each display element is composed of three sub-salbences of Re (1 Green Blue, RGB). Subpixel) is a color filter (CF). Generally speaking, the size of the sub-halogen is much smaller than the range that can be distinguished by the human eye, and the color mixing effect can be achieved in human visual perception. The spatiality of the TFT-LCD If the color mixing is replaced by temporal color mixing, it is necessary to use a color filter to form a color mixing effect' and directly use different colors: the backlight is matched with the relative data age, that is, the temporal color mixing effect can be achieved, that is, the module can be increased.

However, since the human eye often causes random saccades or tracks the instinct of moving objects in the squat surface, the color fields of the objects do not fall at the same point of the retina. Therefore, when the color sequence domain is used, the field visually has fine objects. The phenomenon of Color·Break Up appears at the edge, so that the user's visual experience is not good.

[Embodiment] FIG. 1 is a method (S) for controlling a color field switching frequency according to the present invention. Please refer to _i. In this embodiment, the method for determining the face update rate (10) of the color sequence display includes the following steps. Debt test 201234345
107199ITW 36830twf.doc/I 輸入k號的晝面輸入頻率(步驟SU〇)。接著,依據一運 算式進行計算後求得多個晝面參考頻率,其中上述運算式 為晝面輸入頻率乘以多個參考值,且這些參考值相關於色 序顯示器的色場數(步驟S120)。進一步來說,本實施所 述的運算式為flx(n±k/s),其中fi為輸入信號的畫面輸入頻 率’ s為色序顯示器的色場數,η及k分別為正整數,且S 與k互質,而(n±k/s)經運算後會得到多個參考值。 進一步來說,η的定義為單一畫面的色序循環倍率。 以4個色場(在此以RGBG為例)的晝面而言,若η為3, 則單一晝面的色場循環為“RGBG RGBG RGBG”,其中R 為表示紅色色場,G為表示綠色色場,Β為表示藍色色場。 在理論上,η越大越好,但受限於顯示面板的液晶反應速 度’以避免晝面顯示異常。另一方面,k的定義為不同晝 面間色場顏色的變換數目,亦即相鄰畫面的第一個色場的 顏色順序的差距。若k設定為1時,則表示在每次晝面切 換時’每個晝面的第一個色場的起始顏色的順序會前移一 位。以4個色場(在此以RGBG為例)的晝面而言,若k 為1且η為1 ’則當下畫面的色場循環為“RGBGr”,下一 個畫面的色場循環為“GBGRG”,再下一個晝面的色場循 環為“BGRGB”,以下貝ij以此類推。 舉例來說,以4個色場(在此以RGBG為例)的晝面 為例’ η設定為3,k設定為3 ’則單一畫面的色場數為107199ITW 36830twf.doc/I Enter the kneading input frequency of k (step SU〇). Then, a plurality of facet reference frequencies are obtained according to an operation formula, wherein the operation formula is a face input frequency multiplied by a plurality of reference values, and the reference values are related to the number of color fields of the color sequence display (step S120) ). Further, the operation formula described in this embodiment is flx(n±k/s), where fi is the input signal's picture input frequency 's is the number of color fields of the color sequence display, and η and k are positive integers, respectively. S and k are relatively prime, and (n±k/s) is operated to obtain multiple reference values. Further, η is defined as the color sequential cycle magnification of a single picture. In the case of four color fields (in this case, RGBG is taken as an example), if η is 3, the color field of a single facet is “RGBG RGBG RGBG”, where R is the red color field and G is the representation. The green color field, Β indicates the blue color field. In theory, the larger the η, the better, but limited by the liquid crystal reaction speed of the display panel to avoid abnormalities in the facet display. On the other hand, k is defined as the number of transformations of the color field colors between different vertices, that is, the difference in the color order of the first color field of adjacent pictures. If k is set to 1, it means that the order of the starting color of the first color field of each face will advance one position each time the face is switched. In the case of four color fields (here, RGBG is taken as an example), if k is 1 and η is 1 ', the color field of the current picture is “RGBGr”, and the color field of the next picture is “GBGRG”. ", the next color field cycle is "BGRGB", the following Bay ij and so on. For example, taking four color fields (here, RGBG as an example) as an example, η is set to 3, k is set to 3 ’, and the number of color fields of a single picture is
4x3+3=15。若當下晝面的色場循環為“Rgbg RGBG rgbG4x3+3=15. If the color field of the current face is cycled as "Rgbg RGBG rgbG
RGBG RGB” ’下一個畫面的色場循環為“G RGBG RGBGRGBG RGB” ’ next color field loop is “G RGBG RGBG

J. It is assumed that the input frequency of the input signal is 60 Hz. The number of color fields of the color sequential display is 3. When η and k are equal to 1, the reference frequency calculated by the above formula is 40 Hz, 80 Hz; when n is equal to i and k is equal to 2, then The reference frequency calculated by the above formula is 2〇Hz, 100 Hz; when η is equal to 2 and k is equal to 丨, the reference frequency calculated by the above formula is 100 Hz, 140 Hz, and the remaining values can be It is obtained by taking the calculation formula by itself, and will not be described here. Suppose the input frequency of the input signal is 6〇Hz, and the number of color fields of the color sequence display is 4. When n and k are equal to 1, then according to the above The reference frequency calculated by the calculation formula is 45 Hz, 75 Hz; when η is equal to ! and let it be equal to 3, the reference frequency calculated by the above formula is 15 Hz, 105 Hz; when n is equal to 2 and When k is equal to 〗, the reference frequency of the picture calculated according to the above expression is 1〇5Hz, L35Hz, the remaining values ^ can be obtained by bringing the calculation into the equation, and will not be described here. 2 and 4 will not be mutually homogeneous, so in this embodiment, 2 will not bring the operation. Finally, the selection is greater than 昼According to the face-to-face reference frequency of the input frequency, the color field switching frequency of the color-sequence display is adjusted according to the step (step).

Moreover, a picture reference frequency greater than the input frequency of the face and close to the input frequency of the face can be selected to avoid the insufficient write time of the display panel and affect the quality of the display. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart showing a method of controlling a color field switching frequency of a color sequential display according to an embodiment of the present invention. 2 is a schematic illustration of a field sequence during a plurality of facets in accordance with an embodiment of the present invention. 3 is a schematic diagram of a field sequence during a plurality of kneading surfaces in accordance with another embodiment of the present invention. Figure 4 is a plot of a field sequence during a plurality of kneading periods in accordance with a comparative embodiment.
