Inserting a black surface method involves inserting a black image between two images, and the flashing backlight method includes the light source of the backlight module at a specific time in the pixel time. Yang, the poor black screen method touches the light source of the f-light view, thus making the energy rate lower. In addition, the ray of light rayed by the _f light method will also reduce the energy efficiency and accelerate the loss of the lamp in the backlight module. Figures la, lb, and lc show schematic diagrams of liquid crystal transmittance, back-level brightness, and panel display redundancy using a conventional image display technology. As shown in the figure, the light output from the backlight module has a fixed brightness (500 nits). When the liquid crystal transmittance is changed from 〇% to 6〇%, the brightness of the panel display will gradually increase from 〇 nit to 3〇〇 nits. Since the human eye moves by tracing the object, the change of the display brightness of the panel caused by the liquid crystal transition state in the liquid crystal layer can be observed from the edge portion of the image, which is the cause of the dynamic paste phenomenon. Therefore, the longer the interval between the brightness changes of the panel display, the more obvious the dynamic blur phenomenon observed by the human eye. SUMMARY OF THE INVENTION An object of the present invention is to provide an image optimization method for a liquid crystal display device. The method of the present invention is to reduce the degree of dynamic blurring caused by human eyes for image conversion. The purpose is to provide the image-optimized body brightness of the county-level display device while reducing the degree of dynamic blurring while maintaining the entire image of the display image for the purpose of providing an image optimization method for the liquid crystal age device. Dynamic blur improves display contrast. ❹ (4) Providing an image display device of the m display device, comprising controlling the backlight module to emit at least two chains of different wires to the liquid crystal layer in different portions of the time period, and the wire may be divided into at least one a brightness light and a second brightness light. In addition to the liquid crystal driving signal originally used for driving the liquid crystal layer to control the liquid crystal transmittance, the image optimization method of the present invention also includes outputting a liquid crystal compensation Hexun signal for driving the liquid crystal layer simultaneously with the original liquid crystal driving signal. - Step to increase the liquid crystal transmittance of the liquid crystal layer for more light from the backlight module. [Embodiment] The present invention discloses an image optimization method for a liquid crystal display device, which is configured to control, according to data of a display image, a backlight module to output at least two different lights to a liquid crystal layer while controlling steering of the liquid crystal layer and wearing the same. Transmittance to maintain the brightness of the displayed image while reducing the human eye's perception of motion blur. The liquid crystal display device comprises a backlight module and a liquid crystal panel, wherein the liquid crystal panel display brightness of the liquid crystal display device is corresponding to the brightness of the light emitted by the thin group and the transmittance of the liquid crystal layer. If the backlight module emits light having a brightness of side nits toward a liquid crystal layer having a transmittance of 6%, the liquid crystal display device will have a panel display luminance of substantially 0.6* side = 24 Qnits. Fig. 2a, Fig. 2b and Fig. 2c are respectively a first schematic view showing the brightness of the liquid crystal layer, the brightness of the back domain group and the brightness of the panel display after the image optimization method of the present invention. As shown in FIG. 2a, FIG. 2b and FIG. 2c, the image optimization method of the present invention substantially controls the torsion (liquid crystal transmittance) of the liquid crystal layer and the brightness of the output light of the backlight module in a period of time, wherein the backlight The color of the output light of the module is preferably white, but is not limited thereto; in different embodiments, the backlight module can also output light having other combined colors. In addition, in the embodiment shown in FIG. 2, FIG. 2b and FIG. 2c, the time period 4〇〇 is divided into at least a first time & 410 and a second time period 420′, wherein the first time period 41 is first on the time axis. In the second time period 420. In this embodiment, the time lengths of the first time period 41〇 and the second time period 420420 are substantially equal to each other, but are not limited thereto; in different embodiments, the time lengths of the first time period 410 and the first time period 420 may also be Different from each other according to the needs of the design. In the embodiment shown in Figure 2a, the liquid crystal layer is driven by an electronic signal such that the liquid crystal transmittance is increased to 80% via 〇%. At the same time, as shown in Fig. 2b, the backlight module outputs light having two different brightnesses; in other words, the backlight module outputs first brightness light (100 nits) and second brightness light (500 nits). The first brightness light and the second brightness light are calculated according to a reference backlight driving signal, wherein the reference backlight driving signal can be used to drive the backlight module to output the reference brightness light. In this embodiment, the reference backlight driving signal is calculated according to the pixel pixel data (4), wherein the visual pixel data is data including a display surface required for the liquid crystal display device. In this embodiment, the rising curve shape of the panel display brightness in the first time period 41〇 and the second time period 420 is calculated according to a reference value; the panel display inequality is in the first time period 410 and the second time period 42. The ascending curve morphology is essentially the cube and the third root of the reference value. The above reference ❹ value is the value of the straight line, which corresponds to the panel display brightness output when the reference brightness light is used to display the panel, but is not limited thereto. Since the human eye is mainly responsible for the time required for the panel ride to be brighter than the target brightness of 1 (U rises to 9〇% of the target brightness; therefore, shortening the time required for the above increase will also reduce the human eye. The effect of dynamic blurring. Since the panel display brightness has an exponential function curve, it is therefore required to increase from the maximum brightness of 10% to _ when the time is short. It can be seen that the use of this image is optimized for noisy liquid crystal display. It can be mentioned that the best resistance is __Wei. In addition, as shown in Figure c, the total shell of the alizarin is the area under the curve of the panel display brightness. It can be seen that the image optimization method can concentrate the panel display brightness substantially. The first time period 420 is to maintain the total brightness required for the pixels while improving the dynamic blurring phenomenon. In the embodiment shown in FIG. 2a and FIG. 2b, the backlight module has the output in the first time 10 a light of 100 nits and outputting light having a second brightness (10) nits in the second period 4f; in other words, the brightness of the light outputted by the backlight group is from the first period 410 to the second period 8 201013627 420 cut . However, in different embodiments, the backlight module can also determine the timing of changing the brightness of the output light according to other different conditions of the liquid crystal transmittance. For example, the present invention can set the door gambling of the liquid crystal through, and the liquid crystal transmittance of the wire is substantially 4 when the threshold value is switched. In addition, in the embodiment shown in FIG. 2a and FIG. 2b and FIG. 2c, in order to increase the brightness of the panel, the switching method can be driven by the liquid crystal driving signal according to the output-liquid crystal gamma signal. The liquid crystal ❹ phase lifts the weight reduction liquid. The liquid compensation gamma can be calculated based on the first brightness and the second brightness of the backlight module, but is not limited thereto, and the liquid crystal compensation driving signal can also be calculated according to other liquid crystal transmittances. The relationship between the liquid crystal compensation driving signal and the first brightness and the second brightness may be recorded in a compensation signal lookup table and stored in a data storage device for the data processor to accelerate the calculation of the liquid crystal compensation driving signal. In general, the liquid crystal layer of the liquid crystal display device finally achieves a liquid crystal transmittance of 6〇%. However, in the embodiment shown in the figure, the liquid crystal layer transmits both the liquid crystal driving signal and the liquid crystal compensation driving signal. Drive to achieve 8〇% liquid crystal transmittance. 3a, 3b, and 3c are first schematic views showing the liquid crystal transmittance, the brightness of the backlight module, and the brightness of the panel after the image optimization method of the present invention. In this embodiment, the rising curve patterns of the panel display brightness in the first time period 410 and the second time period 420 are substantially the fifth and fifth root numbers of the reference value, respectively. Therefore, the time required for the panel display brightness to rise from 10% to 90% of the maximum brightness is shorter than that of the previous embodiment, which also means that the embodiment can provide better anti-dynamics than the embodiment shown in Figures 2a, 2b and 2c. Mold 201013627 paste effect. In addition, the image optimization method of this embodiment is substantially the same as the above embodiment and therefore will not be further described herein. ❹

In the present embodiment, the panel display brightness is zero in the rising curve form of the first period 410 and the second period 420, respectively, and the fifth root of the reference value. In other words, the backlight mode is in a closed state in the first period 41 〇. Since the display brightness of the panel is zero in the first period, the liquid crystal light of the liquid crystal system of the present embodiment is gradually increased to be used in order to maintain the overall brightness of the pixel in the period of the period. More light passes in the second time period. In addition to this, the embodiment of the present embodiment of the image quality optimization method is also not prudent. In addition, the image optimization method of the present invention preferably performs the liquid crystal layering action and the action of the backlight module outputting light; in other words, in the period of time, the backlight module is before the liquid crystal transmittance of the liquid crystal layer reaches a fixed value. It is already open. In the embodiment of the present invention, the image optimization method can perform the transition state of the liquid crystal layer in any part of the period of the period and control the output light of the shed towel during the backlight mode; therefore, the panel can be completed in the liquid crystal layer ( Before reaching a fixed value, it has begun to output the light with brightness M. In different implementations, the film and the new method can also select the mixed state of the liquid crystal layer at different time points and the light of the backlight module.
