World’s First HTPS Panels for 3D 3LCD Projectors by EPSON
One of the most commonly method in displaying 3D images is called “frame-sequential 3D”, which requires the viewer to wear special glasses equipped with lenses that server as active shutters which would alternately block and transmit light. This method will display on a screen a series of alternating frames, where each frame carries an image destined for either the right or left eye. The active shouter glasses are synchronized with the displayed images so that only the right shutter is open when the frame for the right eye is displayed and only the left shutter is open when the frame for the left eye is displayed. This rapid alternation of the frames provides a sense of depth to the viewer, perceiving the images in 3D. Having said that, one of the major issues with “frame-sequential 3D” format occurs in an ordinary LCD panel, where both shutters at some point in time need to be closed for a certain period of time to stop the viewer seeing the overlapped left and right images, causing the degradation of image brightness if both shutters are closed for a long period of time. To solve this problem, the developers of such system increased the refresh rate to 240 Hz, which translates to 240 frames per second. However the consumer still expressed dissatisfaction with quality of image brightness in spite of higher refresh rate. Read more
Development of Industry’s First Reflective HTPS TFT Liquid crystal Panels by Seiko Epson
Seiko Epson has made an announcement on release of world’s first reflective high temperature polysilicon (HTPS) TFT liquid crystal panels for 3LCD projectors. The new display panel supports full HD contents and it measures only 0.74 inches on the diagonal. The new panels fuse the reflective display technology with the HTPS technology, providing a device level contrast ratio of 100,000:1 or higher, and ability of providing natural looking images and rich gradations.
