Abstract: A display panel including a plurality of pixel areas and at least a non-pixel area located between two adjacent pixel areas; a substrate; a pixel definition layer located on one side of the substrate, the pixel definition layer including a pixel definition structure located in the non-pixel area and an opening located in the pixel area; a blocking part, the blocking part being disposed on a side of the pixel definition structure away from the substrate; and a light emitting device layer, the light emitting device layer including an organic common layer, the organic common layer being located on a side of the blocking part away from the substrate, where the blocking part includes at least one protrusion, the protrusion including a first bottom surface close to the substrate, a first sidewall, and a second sidewall opposite to the first sidewall.

Abstract: A multi-antenna system and an electronic device comprising the same. An intelligent multi-antenna solution in which antennas are laid out at the top, the side, and the bottom of an electronic device is used, so that three antenna groups including a top antenna group, a middle antenna group, and a bottom antenna group are respectively formed, and antenna performance in a plurality of scenarios such as a free-space scenario, a portrait-mode holding scenario, and a landscape-mode holding scenario is considered, to improve antenna radiation efficiency.

Abstract: Provided are an organic light-emitting diode (OLED) lamp panel and a lighting device. A display region of the lamp panel includes at least one main display region and a display peripheral region. The main display region is regular in shape and is formed by splicing multiple main light-emitting units of the same shape. The display peripheral region consists of a peripheral region I and/or a peripheral region II. The peripheral region I is formed by multiple first peripheral light-emitting units with regular shapes. The display region of the OLED lamp panel is designed to include at least one main display region and a display peripheral region.

Abstract: Apparatus for detecting the oscillation amplitude of an oscillating object (3) includes an optical radiation source (9) and a detector (10) including first and second optical radiation sensing areas (24A, 24B) adjacent each other. The detector (10) and the optical radiation source (9) are adapted to be located opposite each other with the oscillating object (3) located between the source (9) and the detector (10) so that the object (3) blocks a portion of the sensing areas (24A, 24B) from receiving optical radiation from the source (9). A processor (18) coupled to the detector (10) receives first and second output signals representing the magnitude of optical radiation sensed by the first and second optical radiation sensing areas (24A, 24B), respectively. The processor (18) processes the first and second output signals to obtain an indication of the amplitude of oscillation of the object (3).
