20130278155 | BACKLIGHT DRIVE VOLTAGE CONTROL DEVICE, BACKLIGHT DRIVE VOLTAGE CONTROL METHOD AND TELEVISION - A backlight drive voltage control device, comprising: a detecting unit connected to a controller, which detects the current states of the lamp strings of the divisions of the backlight sources of a liquid crystal screen, sends feedback signals to the controller; the controller which sends a voltage adjustment control signal to an AC to DC converter according to the feedback signals, and acquires the voltage adjustment amount of each lamp string according to the voltage adjustment control signal, selects lamp strings which voltage adjustment amounts are larger than the threshold, and sends the closing feedback control signal to the detecting unit; and the AC to DC converter which outputs corresponding voltages to the lamp strings according to the voltage adjustment control signal. | 10-24-2013 |
20140028664 | IMAGE DISPLAY METHOD - The present application provides an image display method and device. A frame of 3D image including a left eye image and a right eye image is received, two fields of compensation images are inserted between the left eye image display and the right eye image display, so that the superposed effect of displaying four fields of images of the frame of 3D image is the left eye image or the right eye image, to achieve a 2D image, furthermore, the left spectacle lens of the 3D glasses is opened when the left eye image is displayed, the right spectacle lens of the 3D glasses is opened when the right eye image is displayed, and both the left spectacle lens and the right spectacle lens are closed when the compensation images are displayed, to achieve the 3D image display. | 01-30-2014 |
20140118340 | 2D/3D POLARIZED DISPLAY METHOD AND DEVICE - The invention proposes a novel 2D/3D polarized display method, polarized display device and a 2D/3D television, applied to the polarization 3D technology; through compensation calculation on the original left-eye and right-eye image signals and alternate time domain display of the images, and through the addition of information on the compensation images in time and space, and in cooperation with control of the opening and closing of the polarization 3D glasses, while viewers wearing the polarization 3D glasses can experience good 3D effect, other viewers with naked eyes can view clear 2D images, so that the 3D viewers and the 2D viewers do not affect each other. | 05-01-2014 |
