Embodiment

[0058] The display system includes a light collimation module and a light viewing angle switching module arranged on the light output side of the light collimation module.

[0059] Among them, the structural diagram of the above-mentioned light collimation module is as follows: figure 2 The module includes a light source 1, a reflective film 2, a light guide plate 3 and a reverse prism film. Printed dots, the light guide plate makes the outgoing light concentrated at the included angle α=10°, the cross section of the reverse prism 50 in the reverse prism film (perpendicular to the above-mentioned first light guide surface) direction is a triangle, and the three angles of the above-mentioned triangle are respectively are 80°, 50° and 50°, and the angle of 80° is a base angle close to the light source.

[0060] The structural diagram of the light viewing angle switching module is as follows: figure 1 , the light angle viewing angle switching module includes a first conductive...

Abstract

The invention provides a display system. The display system comprises a light collimation module and a light view switching module, and the light view switching module is arranged on an emergence side of the light collimation module and comprises a first conductive film, a second conductive film, a diffusion structural film and an electro-optical material. The first conductive film is arranged on one side close to the light collimation module, the second conductive film is opposite to the first conductive film, a gap is reserved between the first conductive film and the second conductive film, and the diffusion structural film is arranged in the gap. A surface, away from the first conductive film or the second conductive film, of the diffusion structural film is a first surface which is a concave lens surface or a convex lens surface, and the first surface comprises a plurality of microstructures arrayed sequentially. The electro-optical material is arranged in the gap and positioned on the first surface. The display system is simple in optical structure and low in energy consumption, and peep-proof display can be realized.

Description

technical field [0001] The present application relates to the field of anti-peep display, and in particular, to a display system. Background technique [0002] At present, there are many kinds of anti-peep display systems on the market. There are two main technologies to realize anti-peep display. The first one is the anti-peep film technology of 3M Company. It can be projected, and the observer can only see it clearly in the front, but not at the position with a large angle; the second is the switching angle technology adopted by HP in the two notebooks of EliteBook 1040 and EliteBook 840. Combining the different curvature structures of the inverse prism to realize the change of the viewing angle, and then realize the anti-peep state of the narrow viewing angle and the non-peeping state of the wide viewing angle. [0003] Among the above two anti-peeping display systems, the first one can achieve better results, but it can only be used in a small angle range and cannot be ...
