Near-to-eye display device and wearable apparatus

A near-to-eye display device, comprising:

• a pixel island array, a micro-lens array and a filter layer, wherein the pixel island array and the micro-lens array are fixed with respect to each other and are spaced apart from each other, the micro-lens array comprises a plurality of micro-lenses,
• the pixel island array comprises a plurality of pixel islands in one-to-one correspondence with the plurality of micro-lenses, and each of the plurality of pixel islands is configured to emit light to a corresponding micro-lens such that the light reach a predetermined viewing position after passing through the corresponding micro-lens;
• the plurality of pixel islands of the pixel island array emit light of a plurality of colors;
• the filter layer comprises a plurality of filter portions in one-to-one correspondence with the plurality of pixel islands, each of the plurality of filter portions is located between a corresponding pixel island and the corresponding micro-lens and is close to the corresponding micro-lens, and a color of each filter portion is the same as the color of light emitted by the corresponding pixel island, and
• the plurality of micro-lenses of the micro-lens array are arranged in a plurality of rows and a plurality of columns, there is no gap between any adjacent two of the micro-lenses in each even row, a distance between any adjacent two of the micro-lenses in each odd row is equal to a diameter of each of the micro-lenses, there is no gap between any adjacent two of the micro-lenses in each odd column, and a distance between any adjacent two of the micro-lenses in each even column is equal to the diameter of each of the micro-lenses.
