51.2: New 240Hz Driving Method for Full HD & High Quality 3D LCD TV

We propose the new 240Hz driving method that includes black frame insertion, LED BLU(back light unit) control and shutter glasses control to reduce crosstalk caused mainly by slow LC response and data scanning driving method. As a result, it realizes 240Hz Full HD 3D LCD TV with average crosstalk about 1% level.

34.2: Field Sequential LC Barrier for a Full Resolution Auto-stereoscopic 3D Display

In this paper, we have developed 15.6 inch auto-stereoscopic 3D display with a field sequential LC parallax barrier which shows the full resolution image of the panel even in the 3D mode. By field sequential switching of a barrier and an image panel, we can compensate the loss of the resolution in the LC barrier type 3D display. We also investigated the field sequential switching effect on the performance of the LC parallax barrier type 3D display.

Stereoscopic display technologies for FHD 3D LCD TV

Stereoscopic display technologies have been developed as one of advanced displays, and many TV industrials have been trying commercialization of 3D TV. We have been developing 3D TV based on LCD with LED BLU (backlight unit) since Samsung launched the worlds first 3D TV based on PDP. However, the data scanning of panel and LCs response characteristics of LCD TV cause interference among frames (that is crosstalk), and this makes 3D video quality worse. We propose the method to reduce crosstalk by LCD driving and backlight control of FHD 3D LCD TV.
