Toshiba Corp developed an LCD panel that enables to zoom in and out an image by bending it and announced the panel at SID 2010, the largest international conference on display technologies.
At the conference, Toshiba actually zoomed in and out an aerial photograph of Google Earth displayed on the screen by bending the LCD panel. The intuitive operation of the bendable panel was drawing attention from many engineers.
The exhibited display had a commercially available bend sensor whose resistance value changes by bending it. The sensor was equipped at the end of the backlight unit.
To realize this LCD panel, Toshiba developed a thin backlight unit that can be bent to a curvature radius of 50mm. It is an edge-lighting LED backlight unit whose light guide plate is as thin as 0.4mm. Also, the company developed software that zooms in and out images in accordance with the change in the resistance value of the bend sensor.
The screen size and resolution of the LCD panel are 8.4 inches and 800 x 600 pixels (SVGA), respectively. The thickness of the glass substrate used for the LCD panel is 0.1mm.
