    摘要： 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.

    摘要： A near-eye display device includes: a pixel island array, a micro-lens array, and a light condensing functional layer. The pixel island array includes one or more pixel islands, the micro-lens array includes one or more micro-lenses, and each pixel island corresponds to a corresponding micro-lens on a one-to-one basis. And the light condensing functional layer includes one or more light condensing components, the positions of the light condensing components corresponds to the position of the pixel islands, and the light condensing components are located between the corresponding pixel island and the micro-lens for condensing lights emitted by the pixel islands. The light condensing functional layer is arranged between the micro-lens array and the pixel island array, and the light condensing components is arranged in the light condensing functional layer corresponding to the pixel islands.

    摘要： 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.
