Parallel LED drive system based on three-dimensional display

Abstract

The invention discloses a parallel LED drive system based on three-dimensional display. A whole LED screen is decomposed into son screens with M rows and N columns; each son screen contains color LEDs with i rows and j columns; each son screen corresponds to a drive circuit, and images of all the son screens are simultaneously displayed in parallel; each drive circuit simultaneously delivers a row of image signals in the son screen into a column of LEDs on the son screen so that a column of LEDs are simultaneously displayed; and the image display of the whole son screen is realized through the sequential scanning of different columns. A PC (Personal Computer) is connected with a PCI-E bridge, an electrooptic conversion module, a photoelectric conversion module, a main control field programmable gate array, a distribution field programmable gate array, an LED drive chip and an LED screen in sequence; and the distribution field programmable gate array is connected with a multipath selection device module, a high-power device module and an LED screen in sequence. The parallel LED drive system based on three-dimensional display realizes high-speed transmission, storage, processing anddisplay of mass data, greatly increases the refreshing rate of images and increases the luminance and resolution ratio of the screen.

Description

technical field [0001] The invention belongs to the fields of volume three-dimensional display and LED display driving methods. In particular, it relates to a parallel LED drive system based on three-dimensional display. Background technique [0002] Three-dimensional display, especially three-dimensional display technology in real space, has always been a display technology that people dream of. [0003] Volumetric 3D display is a technology capable of reproducing image information in a true 3D space with width, height and depth, also known as space-filling display. It excites matter located within the transparent display volume in an appropriate manner to form voxels by the generation, absorption or scattering of visible radiation. When the matter in many directions in the volume is excited, a three-dimensional image composed of many scattered voxels can be formed, floating in the real three-dimensional space, that is, the material world where the observer is, just like ...

Problems solved by technology

And because the existing LED driver chips and related driver circuits are all designed and manufactured for two-dimensional LED screens, these cannot meet the requirements of various parameters in the three-dimensional display. Therefore, it is necessary to use the existing LED driver chips and related Circuit to achieve the parameter requirements of the LED drive screen in the three-dimensional display, it is necessary to change the serial drive mode used in the current LED screen, but must design a new high-parallel LED drive mode
