Abstract
The present invention is for a stereoscopic image display device to achieve enhanced brightness during 3D image display using a switchable barrier and brightness enhancement polarizing films, the stereoscopic image display device includes a backlight unit to transmit light upward, a barrier cell located on the backlight unit, the barrier cell functioning as a barrier when voltage is applied thereto and a transparent cell when voltage is not applied thereto, a first brightness enhancement polarizing film attached to an upper surface of the barrier cell, and an image panel located on the first brightness enhancement polarizing film.
Claims11
A stereoscopic image display device comprising:
- a backlight unit to transmit light upward;
- a barrier cell located on the backlight unit, the barrier cell functioning as a barrier by connecting to a voltage source when voltage is applied thereto and a transparent cell when voltage is not applied thereto;
- a first brightness enhancement polarizing film attached to an upper surface of the barrier cell;
- a second brightness enhancement polarizing film between the backlight unit and the barrier cell;
- and
- an image panel located on the first brightness enhancement polarizing film,
- wherein the first brightness enhancement polarizing film is comprised of a first brightness enhancement layer facing the barrier cell and a first polarizer layer facing the image panel, and the first brightness enhancement layer and the first polarizer layer are contacting each other,
- wherein the second brightness enhancement polarizing film is comprised of a second brightness enhancement layer facing the backlight unit and a second polarizer layer facing the barrier cell, and the second brightness enhancement layer and the second polarizer layer are contacting each other.
