The working principle of circular display screens (including LED circular screens and LCD circular screens, etc.) is similar to that of conventional display screens, but there are also some special features. The following is a detailed explanation of the working principle of circular display screens:
Structural composition:
Spherical unit: multiple spherical units are connected to each other to form a spherical display screen.
Display panel assembly: including warp radiation strips, latitude radiation strips and display panel brackets, etc., used to support and fix the spherical unit.
LED lamp beads: distributed on the spherical unit for luminous display.
Control module: including core control module, unit control board, etc., used to receive image signals and control the on and off and color changes of LED lamp beads.
Display principle:
Image signal input: receive image signals sent by external devices through the control module.
Signal processing: the control module processes the received image signal and converts it into an electrical signal to control the LED lamp beads to emit light.
LED lamp bead control: according to the processed electrical signal, the module controls the LED lamp beads on the spherical unit to emit light according to specific image and video signals.
Image display: since the LED lamp beads are distributed on the surface, special technologies and algorithms are required to achieve the correct display of the image. By controlling the on and off and color changes of LED lamp beads, various contents can be presented on the screen.
Special technology:
Customized module: LED modules are customized individually according to the diameter of the circle to form a circular LED display screen after splicing.
Wiring: Strategic ring wiring and fan wiring are two common layout modes for realizing circular display.
Circuit: The control circuit of LED lamp beads is specially designed to meet the needs of controlling circular display.
Structural composition:
Liquid crystal layer: It is made of two layers of parallel glass supporting liquid crystal materials.
Circular sheet: It is placed on the seventeenth layer of the liquid crystal layer to control the circular direction of light.
Source: Provide enough light for the LCD display to illuminate the liquid crystal layer.
Color filter: Covered on the liquid crystal layer for actual color display.
Driving circuit: Responsible for controlling the arrangement of liquid crystal molecules and parameters such as backlight of the backlight source.
Display principle:
Final control: Apply voltage between two electrodes through the driving circuit to change the arrangement of liquid crystal molecules.
Light brightness: Changes in the arrangement of liquid crystal molecules will change their brightness and brightness capabilities. When the liquid crystal molecules are aligned, light can pass through the two vertex sheets smoothly, showing a bright image; when the liquid crystal molecules are aligned, the light is arranged neatly and the chest is displayed, showing a dark image.
Color display: By controlling the brightness of the red, green and blue color sub-pixels, images of various colors can be synthesized.
Special design:
Circular appearance: In order to adapt to the circular appearance, the liquid crystal layer, dyeing film, color filter and other components of the LCD display need to be specially designed and adjusted.
Driving circuit optimization: The driving circuit needs to be optimized to adapt to the characteristics and needs of the circular display.
Circular display screens have been widely used in many fields, including but not limited to:
Entertainment venues: such as theaters, cinemas, bars, etc., as stage backgrounds or decorative elements.
Commercial venues: such as shopping malls, shopping centers, etc., for playing advertisements and promotional information.
Stadiums: used to display game scores, athlete information, etc.
Transportation hubs: such as railway stations, airports, etc., for playing train information, flight information, etc.
In summary, the working principle of circular displays involves numerous components and complex technical principles. Through special design and optimization, circular displays are able to correctly display images on a surface and are widely evaluated in various fields.
