A diffractive beam expander device (EPE) includes a first spectral filter region (C) and a second spectral filter region (C) to provide a first optical route for blue and green light (B, G), and to provide a second optical router for red light (R). The expander device (EPE) includes a first Bragg grating region (BRG) to enhance optical absorption of red light (R) in the first spectral filter region (C). The expander device (EPE) includes a second Bragg grating region (BRG) to enhance optical absorption of blue light (B) in the second spectral filter region (C).

Optical expander device

This invention relates to an optical expander device with its display device, and a method of light output and image display, including a waveguide plate, the first optical diffractive in-coupling element, the first retrieval unit, the second retrieval unit, the second optical diffractive expander element, the third optical diffractive expander element, and the fourth optical diffractive out-coupling element. The fourth optical diffractive out-coupling element forms part of the first output light (OB), by diffracting guided light, the third retrieval light (B), and the fourth retrieval light (B) to the same direction; simultaneously, the fourth optical diffractive out-coupling element diffracts the first direct-through light (B) and the second direct-through light (B) to the same direction, forming the other part of the first output light (OB). This device of the present disclosure may greatly improve the uniformity of the intensity distribution of the output light.

Optical expander device and its display device and method for outputting light and displaying image

A computer device receives a session message in a group session on a social networking application. The session message includes a child application identifier corresponding to a child application. The device determines a session identifier corresponding to the group session to which the session message belongs. The device transmits the session identifier to the child application and receives from the child application a request for page data corresponding to the session identifier. In accordance with the request, the device obtains the page data corresponding to the child application identifier. The device renders a child application page in a child application according to the obtained data. In accordance with detecting a trigger event corresponding to the child application identifier on the session message, the device invokes the child application in the social networking application.

Method for processing message in group session, storage medium, and computer device

A method for processing a message in a group session of a social networking application is performed at a computer device. The method includes: receiving a session message in a group session; extracting a child application identifier carried in the session message; determining a session identifier corresponding to the group session to which the session message belongs; obtaining page data that corresponds to the child application identifier and that is associated with the session identifier; and rendering, according to the page data, a child application page in a child application that is invoked in an environment provided by the social networking application and that corresponds to the child application identifier.
