[0033] 图2A是本发明一实施例的色序型液晶显示器的色彩调整方法的流程示意图,而图2B是根据图2A的色彩调整方法所绘示的色度图。 [0033] FIG. 2A is a schematic flow diagram of a method of adjusting color sequential type color liquid crystal display device according to an embodiment of the present invention, and FIG. 2B is a chromaticity diagram showing the color adjustment according to the method depicted in FIG. 2A. 请参阅图2A与图2B,关于本实施例的色序型液晶显示器的色彩调整方法,首先,进行步骤S202,也就是将一原始影像信号转换为一目标色点Pl。 Refer to FIG. 2A and 2B, the color adjustment method regarding the embodiment of the color sequential type liquid crystal display, first, the step S202, that is, an original image signal is converted into a target color point Pl.

[0034] 详细而言,目标色点Pl位在一色彩空间的一色度图300内,如图2B所示,其中色彩空间例如是CIE X^色彩空间,而图2B所示的色度图300为CIE 1931色度图。 [0034] Specifically, the target color point Pl bits in a chromaticity diagram of a color space 300, shown in Figure 2B, for example, wherein the color space is CIE X ^ color space chromaticity diagram 300 and FIG. 2B for the CIE 1931 chromaticity diagram. 不过,在其它未绘示的实施例中,色度图300也可以是CIE 1960色度图或CIE 1976色度图。 However, in other not shown embodiments, chromaticity diagram 300 may be a CIE 1960 chromaticity diagram or CIE 1976 chromaticity FIG.

[0035] 原始影像信号可以用来控制液晶显示面板(IXD panel)的液晶灰阶。 [0035] The original image signal may be used to control the liquid crystal display panel GTG (IXD panel) a. 原始影像信号具有一原始红色灰阶值、一原始绿色灰阶值以及一原始蓝色灰阶值。 Original image signal having a gray level value of an original red, green gray level value of an original and an original blue grayscale value. 原始红色灰阶值、原始绿色灰阶值以及原始蓝色灰阶值三者可以属于六位64色灰阶或是八位256色灰阶,且三者可为规一化(normalized)后的灰阶值。 Original red gray value, the green gray value of the original and the original three blue grayscale value may belong to six or eight 64 Color gray gray color 256, and may be three normalized (Normalized) after grayscale value.

[0036] 接着,进行步骤S204,即根据原始影像信号,算出一修改影像信号。 [0036] Next, step S204, i.e., in accordance with the original image signal, calculating a modified video signal. 此修改影像信号具有一白色数据与多个原色灰阶值,其中白色数据可以具有白色灰阶值,而这些原色灰阶值分别为红色灰阶值、绿色灰阶值以及蓝色灰阶值。 This modified video signal having a plurality of primary colors and a white gray level data values, wherein the white grayscale value data may have a white, gray scale values ​​and these primaries are red gray value, the green and blue grayscale value of the grayscale values.

[0037] 算出修改影像信号的方法有多种,而在本实施例中,修改影像信号是透过以下步骤算出。 There are a variety of [0037] calculating method of modifying a video signal, and this embodiment, the video signal is modified is calculated through the following steps in the present embodiment. 首先,根据原始影像信号的原始红色灰阶值、原始绿色灰阶值以及原始蓝色灰阶值,产生上述白色灰阶值。 First, the original value of the original gray level red video signal, and the original value of the original green gray blue gray level value, to produce the white grayscale value.

[0038] 关于产生白色灰阶值的方法,在本实施例中,是从原始红色灰阶值、原始绿色灰阶值以及原始蓝色灰阶值中,以三者最小的灰阶值为作为白色灰阶值。 [0038] The method of white on the gray scale value, in the present embodiment, from the original gray values ​​of red, green grayscale value and the original blue raw grayscale value, a minimum value of the three as a gray white gray scale value. 接着,将原始红色灰阶值、原始绿色灰阶值以及原始蓝色灰阶值皆减去白色灰阶值,以算出这些原色灰阶值,也就是红色灰阶值、绿色灰阶值以及蓝色灰阶值。 Then, the original red grayscale value, the green grayscale value of the original and the original blue grayscale value of white gray scale values ​​are subtracted to calculate these primary color grayscale value, which is the red grayscale value, green and blue grayscale value color grayscale value. 如此,算出修改影像信号。 So, calculate the modified video signal.

[0039] 为了更详细说明以上算出修改影像信号的方法,以下将以八位256色灰阶的标准为例来举例说明。 [0039] In order to modify an image signal calculated by the method described in more detail above, the following criteria will be eight 256-color gradation of an example to illustrate. 假设一原始影像信号所具有的原始红色灰阶值为200,原始绿色灰阶值为150,而原始蓝色灰阶值为50,由于原始蓝色灰阶值为三者最小的灰阶值,因此,白色灰阶值设定为50。 Suppose an original video signal having the grayscale value 200 of the original red, green gray value of the original 150, and the blue gray value of the original 50, since the blue grayscale value of three original minimum gray level value, Thus, the white grayscale value is set to 50.

[0040] 接着,将原始红色灰阶值、原始绿色灰阶值以及原始蓝色灰阶值全部减去白色灰阶值,以得到红色灰阶值、绿色灰阶值以及蓝色灰阶值,其中红色灰阶值为150(因为200-50 = 150),绿色灰阶值为100 (因为150-50 = 100),而蓝色灰阶值为0 (因为50-50 = 0)。 [0040] Next, the original gray values ​​of red, green grayscale value and the original blue raw grayscale values ​​of all the white grayscale value is subtracted, to give a red gray value, the green and blue grayscale value of the grayscale values, wherein the red gray value of 150 (as 200-50 = 150), a green gradation value of 100 (as 150-50 = 100), and the blue gray value 0 (since 50-50 = 0). 如此,修改影像信号得以算出。 So, modify the video signal to be calculated.

[0041] 在进行步骤S204之后,接着进行步骤S206,即利用一矩阵群,将修改影像信号转换为一主色点P2,其中主色点P2位在色度图300内,而矩阵群包括一红光转换矩阵、一绿光转换矩阵、一蓝光转换矩阵与一白光转换矩阵。 After [0041] performing the step S204, followed by step S206, namely the use of a matrix group, the modified video signal is converted into a primary color point P2, wherein the primary color chromaticity point P2 in FIG. 300 bits, and the matrix comprises a group red transformation matrix, a transformation matrix green, a blue and a white conversion matrix transformation matrix.

[0042] 将修改影像信号转换为主色点P2的方法可以包括以下步骤,透过以下的数学式(1)来算出主色点P2: [0042] converting the modified video signal in color point P2 method may include the step of, the dominant color point P2 is calculated through the following equation (1):

[0049] 取得数学式⑴中的红光转换矩阵Mr、绿光转换矩阵Mg、蓝光转换矩阵Mb或白光转换矩阵Mw的方法可以采用以下步骤,并请参阅图1与图3。 [0049] The transform matrix to obtain red light of Mr Equation ⑴, green transformation matrix Mg, blue or white light Mb transformation matrix transformation matrix Mw method steps may be employed, and see FIG. 1 and FIG.

[0050] 本实施例所应用的色序型液晶显示器还具有一液晶显示面板200(如图3所示), 而在取得红光转换矩阵Mr、绿光转换矩阵Mg、蓝光转换矩阵Mb或白光转换矩阵Mw的方法中,首先,将液晶显示面板200的光通量调整为最大值,并仅开启一种单色光源,其它单色光源关闭。 [0050] The color sequential liquid crystal display of the present embodiment is applied comprises a further embodiment of the liquid crystal display panel 200 (FIG. 3), and in obtaining the transformation matrix of Mr red, green transformation matrix Mg, blue or white light conversion matrix Mb Mw transformation matrix method, first, the liquid crystal display panel 200 is adjusted to the light flux maximum and open only one monochromatic light source, a monochromatic light source other closed. 也就是说,只开启某种颜色的单色光源。 That is, open only a monochromatic light source of a certain color.

[0051] 被开启的单色光源可为图1中的单色光源104、单色光源106、单色光源108或白色光源102,其中单色光源104为红色光源,单色光源106为绿色光源,而单色光源108为蓝色光源。 [0051] The monochromatic light sources are turned on in FIG. 1 may be a monochromatic light source 104, a monochromatic light source 106, a monochromatic light source or a white light source 108 102, wherein a monochromatic light source 104 is a red light source, a monochromatic light source 106 is a green light , while monochromatic light source 108 is a blue light source. 另外,在调整液晶显示面板200的光通量为最大值的步骤中,是利用控制液晶显示面板200中的液晶分子排列,让液晶显示面板200具有最高的光穿透率。 Further, in the adjustment of the liquid crystal display panel 200 of the light flux in the step of the maximum value, the liquid crystal display using the control panel 200 of the liquid crystal molecules are aligned so that the liquid crystal display panel 200 has the highest light transmittance.

[0052] 在液晶显示面板200的光通量为最大值,并仅开启一种单色光源的情况下,例如只开启白色光源102或单色光源104-108其中之一,从液晶显示面板200的一显示面202 测出一第一色点。 [0052] In the case where the liquid crystal display panel 200 is at a maximum luminous flux, and turning on only one of a monochromatic light source, for example, open only one monochromatic light source 102 or 104-108 wherein the white light source, a liquid crystal display panel 200 display surface 202 a first color point measured. 第一色点位于色彩空间,其中此色彩空间例如是CIE X^色彩空间,而第一色点可以透过仪器400而测得,且仪器400例如是色度计。 The first color dot is located in the color space, wherein this color space is the CIE X ^ for example, color space, and first color point can be measured through the instrument 400 and instrument 400, for example a colorimeter.

[0053] 接着,将液晶显示面板200的光通量调整为最小值,并仅开启前述已开启过的单色光源。 [0053] Next, the liquid crystal display panel 200 to adjust the light flux to a minimum value, and turns on only the monochromatic light source is turned off. 在调整液晶显示面板200的光通量为最小值的步骤中,也是利用控制液晶显示面板200中的液晶分子排列,使得液晶显示面板200具有最低的光穿透率。 Adjusting the liquid crystal display panel 200 is a minimum flux step, but also the control of the liquid crystal display panel 200 of the liquid crystal molecules are aligned, the liquid crystal display panel 200 having the lowest light transmittance. 理论上,这时候的显示面202理论上应该是呈现黑色,但由于液晶显示面板200难免会发生漏光的情形,因此实际上第二色点所表示的颜色并不会是黑色。 In theory, this time the display surface is of 202 theoretically should appear black, but due to unavoidable circumstances the panel 200 light leakage occurs LCD, so in fact the color of the second color point represented not black.

[0054] 在液晶显示面板200的光通量为最小值,并仅开启前述已开启过的单色光源的情况下,从显示面202测出一位于色彩空间内的第二色点。 [0054] In the liquid crystal display panel 200 is a minimum flux, and turning on only the case where the monochromatic light source is turned off, the measured 202 points in the second color located in a color space from the display surface. 之后,将测得的第一色点与第二色点二者坐标相减。 Thereafter, the first color point and the measured second color point coordinates of the two subtraction. 如此,取得红光转换矩阵Mr、绿光转换矩阵Mg、蓝光转换矩阵Mb与白光转换矩阵Mw。 So, get red light conversion matrix Mr, green transformation matrix Mg, blue and white Mb transformation matrix transformation matrix Mw. [0055] 为了更详细说明以上取得红光转换矩阵Mr、绿光转换矩阵Mg、蓝光转换矩阵Mb或白光转换矩阵Mw的方法,以下将以绿光转换矩阵Mg为例,并配合图1与图3来进行举例说明。 [0055] For a more detailed description of the above transformation matrix made of Mr red light, green light conversion matrix Mg, blue or white light conversion method for converting matrix Mb Mw of the matrix, the Mg matrix converter as an example will be green, and with FIG. 1 and FIG. 3 be exemplified.

[0056] 首先,将液晶显示面板200的光通量调整为最大值,并仅开启绿色光源,即单色光源106,而单色光源104、108以及白色光源102则关闭。 [0056] First, the liquid crystal display panel 200 is adjusted to the light flux maximum, and turning on only the green light, i.e., a monochromatic light source 106, a monochromatic light source and the white light source 104, 108 and 102 closed. 在液晶显示面板200的光通量为最大值,并仅开启绿色光源的情况下,从显示面202测出位于色彩空间内的第一色点(Xgl, Ygl,Zgl)0 Luminous display panel 200 is the maximum value, and only the green light source is turned on in the case of measuring the first color point 202 (Xgl, Ygl, Zgl) positioned within the color space from the display surface of the liquid crystal 0

[0057] 接着,将液晶显示面板200的光通量调整为最小值,并仅开启绿色光源,仍关闭单色光源104、108与白色光源102。 [0057] Next, the liquid crystal display panel 200 to adjust the light flux to a minimum value, and turns on only the green light, a monochromatic light source 104, 108 is still closed with a white light source 102. 在液晶显示面板200的光通量为最小值,并仅开启绿色光源的情况下,从显示面202测出位于色彩空间内的第二色点(Xg2,Yg2,Zg2)。 A case where the liquid crystal display panel 200 is a minimum flux, and turning on only the green light from the display surface 202 measured color point located within the second color space (Xg2, Yg2, Zg2).

[0058] 之后,将测得的第一色点(Xgl,Ygl,Zgl)与第二色点(Xg2,Yg2,Zg2) 二者坐标相减。 After [0058], the first color point (Xgl, Ygl, Zgl) and the measured second color dot (Xg2, Yg2, Zg2) coordinate both subtraction. 也就是将Xgl与Xg2相减,Ygl与Yg2相减,Zgl与Zg2相减,进而得到如下所示的绿光转换矩阵Mg : That is, with Xgl Xg2 subtraction, subtraction Ygl and Yg2, and Zg2 Zgl subtracted as shown below and then get the green light conversion matrix Mg:

[0059] [0059]

Figure CN101866629BD00091

[0060] 同理,以此类推,根据以上绿光转换矩阵Mg的取得方法,取得红光转换矩阵Mr、蓝光转换矩阵Mb与白光转换矩阵Mw。 [0060] Similarly, and so on, according to the above method of obtaining the green Mg transformation matrix, the transformation matrix made of Mr red, white and blue conversion matrix transformation matrix Mb Mw.

[0061] 基于上述,液晶显示面板200难免都会发生漏光的情形,而这对影像色彩会有些影响,以至于主色点P2的坐标可能失真。 [0061] Based on coordinates of the possible distortion, light leakage in the case of the liquid crystal display panel 200 will inevitably occur, and this will have an impact on the color image, so that the dominant color point P2. 然而,透过绿光转换矩阵Mg、红光转换矩阵Mr、蓝光转换矩阵Mb与白光转换矩阵Mw,可以提高主色点P2的正确性。 However, through the green light conversion matrix Mg, transition matrix of Mr red, white and blue conversion matrix Mb Mw of the transformation matrix, can improve the accuracy of the primary color point P2.

[0062] 请参阅图2A与图2B,在进行步骤S206之后,执行步骤S208,即根据主色点P2与目标色点P1,算出多个次图场数据。 [0062] Referring to FIGS. 2A and 2B, the after performing step S206, performs step S208, i.e. the dominant color in accordance with the target color point P2 and the point P1, calculates a plurality of sub-field data of FIG. 这些次图场数据是用来使主色点P2落在目标色点P1。 The secondary field data is used to FIG main color point P2 falls target color point P1. 也就是说,这些次图场数据是要用来修正主色点P2,让色序型液晶显示器能利用白色光源102(请参阅图1)来使像素(pixel)显示目标色点Pl所代表的颜色,进而根据原始影像信号来显示正确的影像。 That is, these sub-field data to FIG main color for correcting points P2, so that color sequential liquid crystal display 102 can use a white light source (see FIG. 1) of the pixel (pixel) display object represented by color point Pl color, and further to display the correct image from the original image signal.

[0063] 在本实施例中,这些次图场数据属于液晶灰阶数据,且可分别为红色图场数据、绿色图场数据与蓝色图场数据。 [0063] In the present embodiment, these secondary data belonging GTG FIG data fields, and field data may be red in FIG, green and blue data fields FIG data field, respectively, in FIG. 详细而言,这些次图场数据可控制液晶显示面板的液晶灰阶, 来修正主色点P2。 Specifically, these sub-field data may FIG controlling the liquid crystal display panel GTG to correct the primary color point P2. 当然,在其它实施例中,也可以同时控制液晶灰阶与光源组件100的发光信号,来修正主色点P2。 Of course, in other embodiments, it can be controlled simultaneously with the light source lighting signal GTG assembly 100, to adjust the primary color point P2.

[0064] 这些次图场数据的方法可以利用以下数学式(¾来算出: [0064] FIG views of these methods using the following data fields Equation (¾ calculated:

[0068] 当主图场为混色图场时,图1中的白色光源102不仅会发出白光之外,単色光源104、106以及108其中至少之一也会跟着白色光源102同时一起发光,所以混色图场的颜色可以是黄色、紫色或橘色等。 Addition [0068] When the main picture field is a field in FIG mixing, in FIG. 1 not only a white light source 102 emits white light, color light sources 104, 106 and 108 radiolabeling wherein the at least one light source 102 will be followed by a white light simultaneously with, the mixing FIG. color field and the like may be yellow, purple, or orange.

[0069] 混色图场的颜色可根据原始影像信号来決定,例如原始影像信号所要呈现的影像为蔚蓝色的海岸与天空的景色,而混色图场的颜色则采用青色(cyan)。 [0069] FIG Field color mixing can be determined according to the original video signal, for example, raw video signal for the image to be rendered views of the coast and blue sky, the color mixing is used in the field of FIG cyan (cyan). 如此,亦可降低色分离现象对画面质量的不良影响。 So, it can also reduce the adverse effects of the color separation picture quality.

[0070] 另外,原始影像信号可以还具有一原始红色背光数据、一原始緑色背光数据以及一原始蓝色背光数据,而修改影像信号的白色数据可以更具有一白色背光数据。 [0070] Further, the original image signal may also have a raw data of the red backlight, a green backlight raw data and an original blue backlight data, modifying the video signal data may further has a white white backlight data. 当主图场为混色图场时,本实施例的修改影像信号的方法不仅会产生白色灰阶值,同时也会产生白色背光数据。 When the field is a mixing master FIG FIGS field, the video signal modification method of the present embodiment not only has a white grayscale value, but also to generate white backlight data.

[0073] 综上所述,本发明是利用白色光源采显示可为白色图场或混色图场的主图场,而此白色光源可为白光发光二极管。 [0073] In summary, the present invention utilizes a white light source may be a white display in FIG mining field or fields of FIG mixing FIG main field, and this white light source may be a white LED. 相较于公知使用红光、绿光与蓝光发光二极管来显示白色图场的方法,本发明不仅可以降低色分离现象对画面质量的不良影响,同时还可以降低瞬间功率。 Compared to known to use red, green and blue light emitting diode display method of FIG white field, the present invention not only can reduce the adverse effect of the color separation picture quality, while reducing the instantaneous power. 如此,本发明能降低色序法液晶显示器的消耗功率,并且增加色序法液晶显示器的操作时间。 Thus, the present invention can reduce power consumption of color sequential liquid crystal display device, and increase the operating time of color sequential liquid crystal display.

[0074] 其次,透过次图场数据,本发明能使主色点落在目标色点,以显示正确的影像颜色。 [0074] Next, FIG times through the field data, the present invention enables color point falls on the main target color point, to display the correct image colors. 纵使白色光源所发出的白光的颜色偏其它颜色(例如6500K的色温),本发明仍可以忠实地显示原始影像信号所要呈现的影像颜色。 Even a white light source color of white light emitted from the other color polarizer (e.g., color temperature 6500K), the present invention can still display the image colors faithfully the original image signal to be presented. 由此可见,本发明不仅能降低色分离现象对画面质量的不良影响,以及降低瞬间功率,而且还可以忠实地显示原始影像信号所要呈现的影像颜色。 Thus, the present invention not only can reduce the adverse effect of the color separation picture quality, and reduce instantaneous power, but also a color image faithful to an original image signal display to be presented.
