摘要:
A touch panel and a touch position detection method are presented. The touch panel includes: a touch unit, a light source unit array positioned along a first edge of the touch unit and including a first light source and a second light source; and a detection unit array positioned along a second edge and including a detection unit generating a detection signal by detecting light from the light source unit array. The first light source radiates light having a first optical axis, the first optical axis extending in a first direction that makes a first angle with respect to a reference direction, and the second light source radiates light having a second optical axis, the second optical axis extending in a second direction that makes the first angle with respect to the reference direction. The reference direction is perpendicular to the second edge.

A light waveguide has a rectangular plate shape and is configured to totally reflect internal light arriving at an angle greater than a critical angle. Light emitting parts are disposed at corners of the light waveguide. Each of the light emitting parts emits light once in a period. A first light receiving part is disposed along a first side surface of the light waveguide, and receives light emitted from the light emitting parts adjacent to a second side surface facing the first side surface of the light waveguide. The second light receiving part is disposed along the second side surface of the light waveguide, and receives light emitted from the light emitting parts adjacent to the first side surface. A detecting part detects a touch position based on an amount of the light received by the first and second light receiving parts.

The present invention relates to a touch module including a light emitting part, a light waveguide, a frustration layer, and a light receiving part. The light emitting part emits light and is disposed along a first direction. The light waveguide includes a first side surface and a second side surface and transmits light incident to the first side surface to the second side surface. The light emitting part is disposed on the first side surface, and the second side surface is disposed opposite to the first side surface along a second direction substantially perpendicular to the first direction. The frustration layer is disposed over the light waveguide and contacts the light waveguide in response to a touch to frustrate a total internal light reflection. The light receiving part is disposed on the second side surface of the light waveguide to detect a position of the touch. The frustration layer includes a plurality of frustration parts, the total internal light reflection is frustrated at a contact surface between a frustration part and the light waveguide, and an area of a first frustration part differs from an area of a second frustration part that is spaced apart from the first frustration part.

An object-sensing device is presented. The device includes a waveguide and a substrate holding a liquid crystal layer, wherein radiation propagates through the waveguide via total internal reflection. A radiation emitting element is positioned along a radiation input surface of the waveguide, and a radiation receiving element is positioned to receive radiation exiting the waveguide. The radiation receiving element may be positioned across the waveguide from the radiation emitting element. Alternatively, the radiation receiving element may be positioned on a surface that contacts the radiation input surface of the waveguide that is optically coupled to the radiation emitting element.

摘要:
In a method for displaying a stereo-scopic image a border for each of multi-viewpoint images is formed around an edge of a display region, and each bordered multi-viewpoint image is converted into a synthetic image. The synthetic image is displayed as a stereo-scopic image in the display region through a lenticular lens inclined by a predetermined angle with respect to a display panel. Therefore, a two-dimensional image may be effectively converted into the stereo-scopic image decreasing saw-edged shapes at the border of the stereo-scopic image, improving display quality.

A white light semiconductor light emitting device includes a semiconductor LED and first and second phosphors provided on a light emitting region of the LED to emit light within a first wavelength range, which is different from that of light emitted from the LED, by absorbing a portion of the light emitted from the LED. The first and second phosphors are respectively a barium-silicate-base green phosphor and a zinc-selenium-base red phosphor.

A display apparatus includes a display panel, a lens plate and a lens driver. The display panel includes a plurality of unit pixels. The display panel is driven by dividing a single frame into N sub frames. N is a natural number. The lens plate is on the display panel. The lens plate includes a plurality of lenses which convert a two dimensional (“2D”) image displayed on the display panel into a three dimensional (“3D”) image. The lens driver disposes the lenses at a first position during a first sub frame. The lens driver moves the lenses to a second position from the first position and disposes the lenses at the second position during a second sub frame. The second position is shifted by 1/N of a width of the unit pixel from the first position.
