Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] An embodiment of the present invention provides a light converging device 100, such as figure 1 As shown, the light concentrating device 100 includes a plurality of light converging mechanisms 110 .
[0030] A plurality of light converging mechanisms 110 are arranged in an array on the light emitting surface 201 of the preset structure 200 of the display panel.
[0031] Each light converging mechanism 110 is a triangular prism including a light incident surface 111 , a first light exit surface 112 and a second light exit surface 113 . The light incident surface 111 of the triangular prism is set towards the light exit surface 201 of the preset structure 200 of the display panel. The refractive index of each light converging me...

The invention discloses a light ray convergence device and a display device, and belongs to the technical field of display. The light ray convergence device comprises a plurality of light ray convergence mechanisms. The light ray convergence mechanisms are arranged in an array manner on a light output surface of a preset structure of a display panel. Each light ray convergence mechanism is a prism comprising a light input surface, a first light output surface and a second light output surface, wherein the light input surface of the prism is arranged in a manner of facing to the light output surface of the preset structure of the display panel; the refractive index of each light ray convergence mechanism is larger than refractive index of external environment; and the included angle between any two surfaces of the light input surface, the first light output surface and the second light output surface meets alpha1> alpha3, and alpha2> alpha3, the alpha1 being the included angle between the first light output surface and the light input surface, the alpha2 being the included angle between the second light output surface and the light input surface, and the alpha3 being the included angle between the first light output surface and the second light output surface. The light ray convergence device solves the problem of low light utilization rate, realizes the effect of improving light utilization rate, and is used for light ray convergence.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a light converging device and a display device. Background technique [0002] With the rapid development of display technologies, displays with wide viewing angles have been widely used. The display with a wide viewing angle allows the user to clearly see the content displayed on the display from various positions of the display, but in some occasions, the user does not want the content displayed on the display to be seen by surrounding people. [0003] There is a light converging device in the prior art, which mainly includes a prism film and an anti-peeping film. Wherein, the prism film is arranged on the light-emitting surface of the display panel to refract most of the divergent light into parallel light perpendicular to the display screen. The anti-peeping film can be an ultra-fine louver structure, which is arranged on the display screen to block other large-angle diverg...
