Viewing Angle Switchable Display with a Compact and Directional Backlight Module
نویسندگان
چکیده
A compact light guide plate (LGP) with special designed microstructures and dual collimated light sources was proposed to achieve an adjustable viewing angle backlight for eco-display. The micro-prisms were utilized to guide the emitting rays toward normal viewing cones while a set of strip patterned diffuser toward wide viewing cones. The uniformity of spatial luminous can reach 91% / 87% at view cone of ±3/ ±60 deg. in each mode. Only 5% of power consumption in narrow viewing angle mode was needed to keep the same luminance in wide viewing angle mode.

Viewing zone of an autostereoscopic display with a directional backlight using a convex lens array
When a directional backlight to each eye alternates synchronously with the alternation of left-eye and right-eye images on the display panel, the viewer can see a stereoscopic image without wearing special goggles. One way to realize a directional backlight is to place a convex lens array in front of dot matrix light sources to generate collimated light. To implement this method, however, defoc...
متن کاملTurning film for widening the viewing angle of a blue phase liquid crystal display.
We report a new turning film structure for widening the viewing angle of a vertical-field-switching blue-phase liquid crystal display, which employs a directional backlight. The turning film consists of periodic prismatic structures: each period has three prisms with different base angles so that the output light can be spread to a larger angle. Simulation results show that a full width at half...

We propose an automatic three-dimensional (3D) pupil tracking backlight system for holographic 3D display system with large image size and full-parallax accommodation effect. The proposed tracking module is applied to a holographic 3D display system with two sets of directional holographic imaging module composed of 2×2 large scale lens array and 22-inch high-resolution liquid crystal display 3...
متن کاملReduction of Image Degradation due to Viewing Angle in Adaptive Dimming Technique
An adaptive dimming technique controls both LCD panel transmittance and its backlight luminance adequately and locally according to the input TV signal. The technique reduces the power consumption and also improves the picture quality. However, a steep change in backlight luminance distribution due to the application of the technique causes image degradation around the boundary of the segments ...
