Embodiment Construction
[0043] In order to solve the technical problem in the prior art that the front fixed grating of the 3D display device will cause the display brightness of the 3D display device to be low. In order to improve the display brightness of the display panel, the embodiment of the present invention provides a new pre-fixed grating structure, that is, the grating module in the following embodiment, the grating module includes slits and grating units arranged alternately in sequence, Any grating unit of the grating module includes: a transparent medium layer close to the light-emitting module, and a reflective layer on the surface of the transparent medium layer, and the intersecting interface of the reflective layer and the transparent medium layer constitutes at least one concave surface facing the light-emitting module. Mirror, because of the concave curved mirror, can receive the optical signal sent by the light-emitting module, and reflect the received optical signal back to the li...

The invention discloses a display panel, a preparation method thereof and a 3D display device. The display panel comprises a grating module, a first substrate, a luminescent module and a second substrate which are arranged successively; the grating module comprises slits and grating units which are arranged alternatively; any grating unit comprises a reflection layer and a transparent dielectric layer, the transparent dielectric layer is arranged in the upper surface of the first substrate, and the reflection layer is laminated on the upper surface of the transparent dielectric layer; and a concave curved mirror in which at least one mirror surface is orientated to the luminescent module is formed in the interface where the reflection layer intersects with the transparent dielectric layer, and the concave curved mirror is used to receive optical signals emitted by the luminescent module and reflect the received optical signals to the luminescent module, so that the optical signals reflected to the luminescent module can be recovered and reused. The display brightness of the display panel is improved.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a display panel, a 3D display device and a manufacturing method thereof. Background technique [0002] The current naked-eye 3D display technology of active light-emitting display devices mostly adopts the method of front prism or parallax barrier, such as figure 1 The schematic diagram of the optical path of the naked-eye 3D display device with the front parallax barrier is shown. Because the slits and gratings of the parallax barrier are arranged alternately in sequence, the image data received by the odd-numbered pixel units on the display panel can be displayed and enter the perspective of the left eye of the person. The image data received by the even-numbered pixel units enters the perspective of the right eye of the person after being displayed, so that the left-eye image seen by the user's left eye is separated from the right-eye image ...
