Optical film and narrow frame display device

摘要

A light-redirecting optical film includes a continuous plurality of micro structures. The micro structures have a common bottom surface and each micro structure includes a first curved surface and a second curved surface. The first curved surface is convex towards the second curved surface. The second curved surface rises from the bottom surface. The first curved surface and the second curved surface meet along a top edge. The curvature of the top edges in the optical film is the same. The first curved surface is a total reflecting surface. A narrow frame display device is also presented.

主权项

1. A narrow frame display device comprising:
a plurality of display units collectively defining an array with no gap between the plurality of display units; each of the display units comprising: a display panel comprising a display surface and a non-display surface opposite to the display surface; a frame being formed on the edge of the display panel and surrounding the display panel; and a backlight module corresponding to the non-display surface; wherein the display units further comprises a central area, a fringe area surrounding the central area and a frame area surrounding the fringe district, the frame corresponds to the frame district, and the display panel corresponds to the central area and the fringe area; and a plurality of optical films being defined on the surface of the display units and corresponding to the frame district and the fringe district, each of the optical films comprising: a plurality of micro structures being continuous and having a common bottom surface, every micro structure comprising a first curved surface and a second curved surface, the first curved surface being convex in relation to the second curved surface, and the second curved surface rising from the bottom surface; wherein the first curved surface and the second curved surface meet and define a top at the line of meeting, the curved direction of the tops in the optical film being the same, and the first curved surface being a total reflecting surface.
