| 20090115718 | LIQUID CRYSTAL DISPLAY METHOD AND THE APPRATUS THEREOF - The present invention discloses a liquid crystal display method, which can adjust the brightness of different segments of backlight according to the different images. Especially, the present invention discloses a liquid crystal display method, which includes: receiving a image signal; analyzing the image signal; dividing the image into at least two image segments according to the analysis result of the image signal; dividing the backlight into at least two backlight segments according to the division result of the image; adjusting the brightness of the backlight in each backlight segment; adjusting the image signal in each image segment. The liquid crystal display method of the present invention divide the image and the backlight according to the image signal, while adjusting the brightness of the image and backlight in each segment to not only decrease the power consumption of the liquid crystal display, but also increase the contrast of the image signal, thereby improving the effect of liquid crystal display. | 05-07-2009 |
| 20090207318 | Control unit, a video device including said control unit, and a control method - The present invention discloses a control unit, a video device employing said control unit and a control method thereof, wherein the control unit includes: a recognition device which is used to recognize the target in the target image; a calculation device which is used to calculate and transform the position coordinate of the recognized imaging target from the recognition device and output the position of the operation unit. | 08-20-2009 |
| 20090251400 | LCD DISPLAY METHOD - The present invention offers a display method, which can adjust the brightness of backlight by the brightness correction of the backlight, thereby not only decreasing the power consumption, but also solving the problem of blinking backlights. Especially, the display method of the present invention comprises: receiving an image signals, calculating the typical brightness of said image signal, calculating the brightness correction of the backlight according to the typical brightness of said image signal and the brightness of the backlight, adjusting the brightness of the backlight according to the brightness correction of the backlight, and adjusting said image signal. The display method of the present invention is correcting the image gray and contrast by applying the algorithm of slow changing of backlight according to the brightness scale of the input image, while adjusting the brightness of the backlight, therefore unchanging or increasing the subjective image effect, preventing the blinking of the backlight and improving the quality of the display. | 10-08-2009 |
| 20100097405 | COLOR GAMUT MAPPING METHOD FOR MULTIMEDIA EQUIPMENT, A TELEVISION AND A COLOR PROCESSING APPARATUS - A color gamut mapping method for multimedia equipment is disclosed. This method performs color gamut mapping on a video signal received by the multimedia equipment and gives an output, wherein the video signal is in a first color color gamut while display light of the multimedia equipment is in a second color gamut. The color gamut mapping method for multimedia equipment comprises the steps of: converting the received video signal into a luminance signal and a chrominance signal, and calculating a two-dimensional plane according to the luminance signal and the chrominance signal, wherein the two-dimensional plane intersects the first color gamut to obtain a first region and intersects the second color gamut to obtain a second region; calculating location of a to-be-mapped point corresponding to the video signal in the first region according to the luminance signal and the chrominance signal of the video signal, and calculating a mapping point in the second region by making calculations on the to-be-mapped point to output a mapping point signal. | 04-22-2010 |
| 20120120206 | METHOD, TV SET FOR DISPLAYING 3D IMAGE AND GLASSES - A method for displaying 3D image is provided in the present invention. The method includes: 3D image signals, which comprise consecutive one frame of left-eye signal and one frame of right-eye signal, are received; the 3D image signals are processed by frequency multiplication, and n consecutive frames of left-eye signals and n consecutive frames of right-eye signals are obtained, n being the times number of the frequency multiplication and equal to or greater than 2; light-emitting diode (LED) driving signals drive the LED to display the n consecutive frames of left-eye signals and the n consecutive frames of right-eye signals; in the n consecutive frames of left-eye signals, the first frame of left-eye signal corresponds to an LED driving signal which is off, the nth frame of left-eye signal corresponds to an LED driving signal which is on, and in the n consecutive frames of right-eye signals, the first frame of right-eye signal corresponds to an LED driving signal which is off, the nth frame of right-eye signal corresponds to an LED driving signal which is on. The present invention also provides a TV set for displaying 3D image and a pair of glasses for viewing 3D image. By the present invention, the problem of crosstalk between leftimage and rightimage is solved, and backlight sources energy consumption and complete apparatus cost are reduced. | 05-17-2012 |
| 20140210841 | METHOD, DEVICE AND SYSTEM FOR COMPENSATING BRIGHTNESS OF A LIQUID CRYSTAL MODULE - A method for compensating the brightness of a liquid crystal module involves acquiring an image of a liquid crystal module to obtain the acquired image. The acquired image of the liquid crystal module is compared with a standard image to find a dark region. The compensation coefficient of each pixel in the dark region is calculated. In a display control circuit of the liquid crystal module, the calculated compensation coefficient of pixels is stored for compensating the backlight unit corresponding to pixels in dark region. | 07-31-2014 |
