摘要： This application provides a light source component, a display apparatus, and a mobile terminal. The light source component includes a first semiconductor layer, a light emitting layer, and a second semiconductor layer that are laminated. The light emitting layer is located between the first semiconductor layer and the second semiconductor layer. A surface that is of the second semiconductor layer and that is away from the light emitting layer is an out-light surface. A side surface of the semiconductor layer has a surface non-radiative recombination center. When the light source component works, the surface non-radiative recombination center captures a carrier in the semiconductor layer, and non-radiative recombination of the carrier occurs on the side surface. This reduces light emitting efficiency of the light source component. To overcome the foregoing problem, the light source component in this application is further provided with a conductive layer. The conductive layer may adjust and control, through electric field force, the carrier to be far away from surface non-radiative recombination centers of the first semiconductor layer and the second semiconductor layer. In this way, the carrier is far away from the surface non-radiative recombination center of the semiconductor layer under an action of the electric field force, thereby reducing a case in which the carrier is captured by the surface non-radiative recombination center, and improving light output efficiency of the light source component.

摘要： This application provides a display panel, a display apparatus, and a preparation method for a display panel. The display panel includes a plurality of pixel units, and each pixel unit includes at least three color subpixels. All subpixels of the pixel unit are packaged into one pixel unit by a passivation layer. Packaging and a transfer at the passivation layer are performed per pixel unit. Compared with transferring a single subpixel, this greatly reduces a quantity of pixel transfers, and reduces a probability of product damage in a transfer process, thereby helping improve manufacturing efficiency and a product yield. In addition, all subpixels of each pixel unit may share one electrode, to be specific, one ends of the subpixels of the pixel unit each are connected to one first electrode, and the other ends of the subpixels of the pixel unit share one second electrode. This can reduce a total quantity of electrodes of the display panel, reduce a quantity of electrodes that need to be welded when the pixel unit is transferred to a substrate with a drive circuit, improve process efficiency, and also improve a yield of the display panel.
