The present disclosure provides a shelf system and a control method. The shelf system includes: a shelf body including an accommodation cavity; an image collection element mounted on the shelf body; a transparent touch display panel mounted on the shelf body and covering at least a part of the accommodation cavity, a light ray passing through the transparent touch display panel at a side away from the shelf body into an interior of the accommodation cavity; and a controller coupled to the transparent touch display panel and the image collection element, and configured to obtain image information collected by the image collection element, obtain a touch operation on the transparent touch display panel, and output a display signal for the transparent touch display panel and/or a control signal corresponding to the touch operation in accordance with the image information and the touch operation.

Shelf system and control method

The present disclosure provides a backlight data transmission method including: receiving, in response to a first vertical synchronization signal of a current image frame sent from a logic circuit board, an entire of backlight data sent from the logic circuit board during a first preset time period, where the entire backlight data includes backlight data corresponding to backlight regions, and duration of the first preset time period is longer than duration of the first vertical synchronization signal in an active level state during one period; and sending the entire backlight data to a backlight driving module during a second preset time period after the first preset time period, where a sum of the duration of the first preset time period and duration of the second preset time period is less than a period of the first vertical synchronization signal.

Backlight data transmission method, micro control unit and local dimming backlight system

A tiled display apparatus includes a main display driving board and display modules. Each display module includes a system board. The main display driving board is coupled to a first stage system board. The main display driving board is configured to receive a display signal, acquire a main screen region display signal, and transmit the main screen region display signal to the first stage system board. The system board is configured to receive the main screen region display signal, and extract a group of main screen region display data corresponding thereto from the main screen region display signal to control a display module to which the system board belongs to display an image according to the main screen region display data. Except for a last stage system board, remaining system boards are each further configured to transmit the received main screen region display signal to a next stage system board.

Tiled display apparatus, tiled display control method, and non-transitory computer-readable storage medium

Embodiments of the present disclosure provide a device and a method for controlling backlight, and a display device. The device for controlling backlight, comprising: a first controlling circuit configured to receive a first power supply signal for controlling a display device to be turned on or off, and generate an output signal for causing a backlight module of the display device to be turned off, in response to the first power supply signal being in a first status for controlling the display device to be turned off; and a second controlling circuit configured to receive the first power supply signal, and generate an output signal for causing the backlight module to be turned on again after being kept in a turned off state for a predetermined time period, in response to the first power supply signal being in a second status for controlling the display device to be turned on.

Device and method for controlling backlight, and display device

The preset disclosure provides a display panel and a display device. The display panel includes: a first substrate; a first bonding electrode which is located on a first surface of the first substrate facing a light-outgoing direction of the display panel and is located at an edge outside a display area of the display panel.

Display panel and display device

Disclosed is a spliced display device and a backlight control method therefor. The spliced display device includes a plurality of display modules that include respective backlight modules. Each of the backlight modules includes a plurality of backlight partitions, of which a first backlight partition is located at edge of a corresponding backlight module of the backlight modules. The backlight control method comprises the steps of obtaining an initial brightness value and a reference brightness value for the first backlight partition, adjusting the initial brightness value of the first backlight partition according to the reference brightness value to obtain an adjusted brightness value for the first backlight partition, and controlling the brightness of the first backlight partition according to the adjusted brightness value.

Spliced display device and backlight control method therefor

The present disclosure provides a display device and a vehicle, and relate to the field of display technologies. When the present disclosure is applied to a vehicle, a driver and a passenger may see different images, and thus user experience is enhanced. A display device includes: a display panel and a light adjusting structure arranged at a light exiting side of the display panel. The light adjusting structure is configured to adjust a direction of exit light from the display panel, such that first images displayed by all first display units in the display panel and second images displayed by all second display units in the display panel are respectively transmitted to a first visible area and a second visible area.

Display device and vehicle

A pixel driving circuit is provided, comprising: a current control circuit configured to provide a constant current signal and an activation signal, a current switching circuit configured to control the transmission of the constant current signal to a light-emitting device under the control of the activation signal, and a grounding control circuit configured to control the current control circuit to provide the constant current signal and the activation signal. An input terminal of the current control circuit is connected to a data line and a power line, respectively. A control terminal of the current switching circuit is connected to an output terminal of the current control circuit, an input terminal of the current switching circuit is connected to the input terminal of the current control circuit, and an output terminal of the current switching circuit s connected to an input terminal of the light-emitting device.

Pixel driving circuit and driving method thereof, display driving circuit, display substrate and display device

A display panel, a manufacturing method and driving method thereof are provided. The display panel includes a light transmittance adjusting layer and two pixel layers being respectively located on opposite surfaces of light transmittance adjusting layer. Each pixel layer includes multiple light-emitting units arranged in an array. Orthogonal projections of two pixel layers on the light transmittance adjusting layer do not overlap. When light transmittance of light transmittance adjusting layer is higher, light emitted from the light-emitting units on both surfaces of light transmittance adjusting layer is emergent from opposite sides through light transmittance adjusting layer. Two pixel layers display the same picture jointly. When light transmittance of light transmittance adjusting layer is lower, light emitted from light-emitting units on both surfaces of light transmittance adjusting layer cannot be transmitted through light transmittance adjusting layer to reach opposite sides. Two pixel layers display images independently.
