A near-to-eye display device and wearable apparatus are provided. The near-to-eye display device includes: pixel islands and micro-lenses in one-to-one correspondence with the pixel islands; wherein each pixel island emits light to a corresponding micro-lens so that the light reaches a predetermined viewing position after passing through the corresponding micro-lens. The near-to-eye display device further includes: super-lens units each including at least one super-lens; wherein the super-lens units are in one-to-one correspondence with the pixel islands; each super-lens unit is on a side of a corresponding pixel island proximal to the corresponding micro-lens, and an orthogonal projection of the super-lens unit on a plane where the corresponding pixel island is located covers the corresponding pixel island. The super-lens unit converges light, which is within a predetermined angle, emitted by the corresponding pixel island, to reduce a diffusion angle of the light emitted by the corresponding pixel island.

The present disclosure relates to a device and a system for testing flatness. The device for testing flatness includes a base, a testing platform, and a ranging sensor. The testing platform is assembled on the base. The testing platform includes a supporting structure. The supporting structure is disposed on the side of the testing platform away from the base and is used to support a to-be-tested board. The structure matches the structure of the to-be-tested board. The ranging sensor is disposed on the side of the testing platform away from the base. After the to-be-tested board is placed on the testing platform, the ranging sensor is used to test distances between a number N of to-be-tested positions on the to-be-tested board and the ranging sensor, to obtain N pieces of distance information, and the N pieces of distance information are used to determine the flatness of the to-be-tested board, where N is an integer greater than 2. According to the embodiments of the present disclosure, the flatness of the glass substrate can be tested to improve the manufacturing process to reduce the flatness of the glass substrate, and avoid the problem that the glass substrate is easily broken when entering the subsequent process equipment and the process equipment is down.

A display panel is provided with a plurality of sub-pixel areas and includes: a base substrate, a light emitting structure including a plurality of light emitting devices corresponding to the sub-pixel areas, an encapsulating layer, and a pixel defining layer. The pixel defining layer includes: a plurality of openings; at least two sub-pixel defining layers, and a quantum dot color film layer. Each of the sub-pixel defining layers is provided with a pixel separator. The pixel separators fence each of the plurality of openings, and define the plurality of sub-pixel areas. In the at least two sub-pixel defining layers, the sectional shape of the pixel separator in the sub-pixel defining layer which is farthest away from the encapsulating layer includes a regular trapezoid. The quantum dot color film layer includes a plurality of quantum dot color films arranged in the corresponding openings.
