Patented technology areas and application scenarios for Superchip's LED display controller with residual shadow elimination function

Superchip with residual shadow elimination function of LED display controller patent technology mainly relates to the display control technology field.

The patented technology is in the field of display control technology:

• The patent is based on a specific circuit design that includes a serial-to-parallel shift register, a control unit, and multiple drive units that work in tandem.
• The control unit can generate drive signals and discharge signals based on the clock signal and the output data signal of the shift register, and the drive unit controls the drive current and discharge current according to these signals.
• The pulse width change circuit can generate the discharge enable signal according to the clock signal, and the pulse width of the discharge enable signal is different from the pulse width of the clock signal, so as to realize the clearing of the stored power of the LED display unit and achieve the purpose of residual shadow elimination.

Application Scenario:

• Indoor and outdoor large-scale LED display: large-scale LED display in airports, stations, shopping malls, stadiums and other places are widely used. These displays usually need to run continuously for a long time, and the display content is rich and varied, switching frequently, which is easy to produce residual shadow. Superchip's technology can effectively eliminate the residual shadow, ensure the clarity and stability of the display screen, improve the visual effect, and provide viewers with a high-quality visual experience, whether it is to play advertisements, display information on the event, or release the movement of flights, and so on, can have a better rendering effect.
• High-definition video display field: such as movie theaters, home theaters and other places that require very high video display quality. LED display controller with residual shadow elimination function can ensure that when playing high-definition video, the picture is smooth, no residual shadow interference, so that the audience can be fully immersed in the wonderful film and television content, to enhance the enjoyment of watching movies.
• Stage performances and cultural activities: In all kinds of stage performances, concerts, cultural evenings and other occasions, LED displays are often used to create a stage atmosphere, show the performance background and special effects. This technology can ensure that the LED display on the stage will not have residual shadow phenomenon when switching the screen quickly and presenting various dynamic effects, making the stage effects more colorful and enhancing the artistic infectious force of the performance.
