Abstract: The present disclosure relates to displays and imaging methods. One example display includes a self-luminous array, a pixel expansion apparatus, and a lens of an optical engine. The self-luminous array includes a plurality of self-luminous pixels that autonomously emit light. The pixel expansion apparatus includes a driver and a transparent flat plate. A light beam emitted by the self-luminous array is imaged on an imaging plane of the lens of the optical engine through the transparent flat plate. The transparent flat plate is driven by the driver. In some instances, for the display module, in a time dimension, a same unit imaging area can display different colors in a time-division manner, and in a space dimension, a shift of a light beam can be controlled.

Abstract: This application provides a display panel, a preparation method therefor, and a display apparatus. A first display region of the display panel has an OLED pixel, a second display region has a Micro LED pixel, the Micro LED pixel has a light emitting region and a light transmission region, and a camera is disposed below the second display region. After the Micro LED pixel is used in the second display region, display pixels having a same area in the first display region and the second display region can be designed, to implement display effect consistency between the first display region and the second display region. Because a size of the Micro LED pixel for light emitting is small, it can be ensured that the Micro LED pixel has a large light transmission region, so that light transmittance of the second display region can be improved.

Abstract: A projection optical engine, an electronic device, and a projection imaging method are provided, to resolve a limitation of the projection optical engine on miniaturization of the electronic device. The light combination apparatus is configured to combine light emitted by one pixel of the first color and light emitted by one pixel of the second color, and then emit combined light. The light emitted by the light combination apparatus is imaged on an imaging plane after passing through the pixel expansion apparatus and the optical engine lens. The pixel expansion apparatus is configured to enable the light emitted by the light combination apparatus to be imaged at different locations on the imaging plane at different moments.

Abstract: An integrated circuit, a control method, and a system are provided, to improve reliability of the integrated circuit. The integrated circuit mainly includes a power supply pin (P1), a configuration pin (P4, P5), a switchable pull-up resistor (KR1, KR2), and a control unit (2011). The integrated circuit can provide a control signal for a target chip (202) by using the configuration pin (P4, P5) of the integrated circuit. In the integrated circuit, a first end of the switchable pull-up resistor (KR1, KR2) is connected to the power supply pin (P1), a second end of the switchable pull-up resistor (KR1, KR2) is connected to the configuration pin (P4, P5), and a control end of the switchable pull-up resistor (KR1, KR2) is connected to the control unit (2011). The power supply pin (P1) can receive a power supply voltage of the integrated circuit.
