Embodiment Construction

[0028] figure 1 is a schematic diagram of a stereoscopic display 100 according to an embodiment of the present invention. The stereoscopic display 100 includes a power supply 110 , a power frequency detector 120 , an ambient brightness detector 130 , a stereoscopic image source 140 , a scaler 150 , a timing signal transmitter 160 , a processor 170 and a display panel 180 .

[0029] The power supply 110 converts indoor power from AC to DC to provide power required by the stereoscopic display 100 . Depending on the location, the indoor power supply will have different voltages and frequencies. For example, the power supply voltage can be 110V or 220V, and the power frequency can be 50Hz or 60Hz. The power frequency detector 120 detects the above power frequency, that is, the power frequency accepted by the stereoscopic display 100 . The ambient brightness detector 130 detects ambient brightness around the stereoscopic display 100 . Stereoscopic image source 140 provides stere...

Abstract

The present invention provides a stereoscopic display device and a vertical updated frequency adjusting method, wherein the stereoscopic display device comprises the following components: a display panel, a time sequence signal transmitter, a power frequency detector, an ambient brightness detector and a processor. The display panel displays the stereo image. The time sequence signal transmitter transmits the time sequence signal. The time sequence signal points out the time when the display panel displays right-eye image and the time when the display panel displays the left-eye image. A power supply frequency detector detects the power supply frequency of the stereoscopic display device. The ambient brightness detector detects the ambient brightness at the periphery of the stereoscopic display device. The processor adjusts a vertical updating frequency of the display panel according to the power supply frequency and the ambient brightness, and causes the time sequence signal transmitter to transmit a time sequence signal that corresponds with the vertical updating frequency.

Description

technical field [0001] The present invention relates to a 3D display, and more particularly to a vertical refresh rate of a 3D display. Background technique [0002] For the current stereoscopic display, take the 120Hz model as an example, the vertical update frequency that can be set in the stereoscopic mode generally includes 100Hz, 110Hz and 120Hz. Taking 100Hz as an example, 50Hz is used to update the image of the left eye, 50Hz is used to update the image of the right eye, and then the left eye of the shutter glasses (shutterglasses) is opened 50 times a second, and the right eye is also opened 50 times a second. Typically a vertical update frequency of 100 Hz is used in countries where the mains frequency is 50 Hz. For 120Hz, 60Hz is used to update the image of the left eye, and 60Hz is used to update the image of the right eye. Then the left eye of the shutter glasses is opened 60 times a second, and the right eye is also opened 60 times a second. A vertical update ...
