Abstract: The present application provides a display panel, a manufacturing method of the display panel, and a display terminal. The display panel includes a base substrate. The base substrate comprises a first substrate, a semi-interpenetrating net structure layer, and a second substrate stacked on each other. The semi-interpenetrating net structure layer is formed by curing after interpenetration between a material of the first substrate in a partially cured state and a material of the second substrate in an uncured state. Accordingly, a bonding strength between the first and second substrates is increased, inert properties between them are reduced, and production yields in separating a glass substrate from the first substrate are improved.

Abstract: The present invention relates to a reflective eyepiece optical system and a head-mounted near-to-eye display device. The system includes: a first optical element and a second optical element which are arranged sequentially along an incident direction of an optical axis of human eyes, and a first lens group located on an optical axis of a miniature image displayer; wherein the first optical element and the second optical element are used for transmitting and reflecting an image light from the miniature image displayer; the first optical element reflects the image light passing through the first lens group to the second optical element, and then transmits the image light reflected by the second optical element to the human eyes.
Abstract: A mosquito repeller includes a casing, a mosquito repellent liquid bottle, and a first heating element installed in the casing. The first heating element includes a first heat-generating body and a cotton swab. The first heat-generating body is inserted into the cotton swab, and an end of the cotton swab away from the first heat-generating body extends into the mosquito repellent liquid bottle. Since the first heat-generating body is inserted into the cotton swab, heat is concentrated at the center of the cotton swab, and the cotton swab is heated uniformly, and the vaporization of the mosquito repellent liquid is stable to improve the mosquito repelling effect of the mosquito repeller, while reducing the power consumption of the mosquito repeller, saving energy, avoiding a temperature rise of components near the heat-generating components, retarding the ageing of components, and extending the service life of the mosquito repeller.
