|20150370746||BIDIRECTIONAL DATA TRANSMISSION SYSTEM - A system for bidirectional signal transmission may comprise a forward data transmission circuit to unidirectionally transmit a first input signal and a backward data transmission circuit to unidirectionally transmit a second input signal. The backward data transmission circuit may comprises a logic circuit to detect a voltage difference over a resistance element in the forward data transmission circuit. When the voltage difference is lower than a threshold value, the logic circuit outputs a first voltage level. When the voltage difference is greater than or equal to a threshold value, the logic circuit outputs a second voltage level different from the first voltage level.||12-24-2015|

|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|
|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|
|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.
