Abstract: A remote control device sends a patterned infrared signal to the display device. A display device receives the patterned infrared signal by using a plurality of infrared receivers. The display device obtains a projection pattern of the patterned infrared signal on a display screen. The display device determines a pointing position of the remote control device on the display screen based on the projection pattern. The display device displays a prompt mark in the pointing position of the display screen, where the prompt mark is used to prompt a user with the pointing position of the remote control device on the display screen.

Abstract: An LED print drive method is applied to an LED array. The LED array includes a plurality of LED partitions, each LED partition includes one or more LED lights, and the plurality of LED partitions are distributed in a staggered manner based on a specified sequence. A print control unit generates a plurality of groups of data signals, and a drive control unit receives the plurality of groups of data signals from the print control unit. The drive control unit converts the plurality of groups of data signals into a plurality of groups of LED drive signals, and the drive control unit drives, in a time-sharing manner with the plurality of groups of LED drive signals, a corresponding LED partition to emit light. Light-emitting time of each LED partition corresponds to distribution of each LED partition.

Abstract: An example backlight module, an example display, and an example mobile terminal are provided. The backlight module includes a backplane having a light reflecting surface, a light source layer disposed on the light reflecting surface, and at least one light mixing component disposed on the light source layer. The light source layer has at least one point light source, and the at least one light mixing component is in a one-to-one correspondence with the at least one point light source. Each light mixing component includes a light reflecting layer configured to reflect some light rays emitted by a corresponding point light source, and a light transmission layer configured to transmit a light ray reflected by the light reflecting layer and further reflected by the light reflecting surface. The light reflecting layer is disposed above the light source layer and is configured to reflect some light rays emitted by the corresponding point light source.

Abstract: A display apparatus includes a backlight component, a light adjusting component, a display panel, and a first polarizing film. The backlight component is configured to generate polarized light. The light adjusting component is disposed on one side of the backlight component, and is configured to deflect or not deflect polarized light generated by the backlight component. The first polarizing film is disposed between the light adjusting component and the display panel. In the display apparatus) provided in this application, when the polarized light obtained after passing through the light adjusting component passes through the first polarizing film, if a vibration direction of the polarized light is consistent with a transmission direction of the first polarizing film, the polarized light can be transmitted. If the vibration direction of the polarized light is perpendicular to the transmission direction of the first polarizing film, the polarized light cannot be transmitted.
