Parallel LED driving method and system based on three-dimensional display

Abstract

The invention discloses a parallel LED drive method based on three-dimensional display and a system thereof. A whole LED screen is divided into M rows*N lists of sub-screens; each sub-screen includes I rows*j lists of color LED pipes; each sub-screen is corresponding with one drive circuit; and images on every sub-screen are all displayed in parallel. Every drive circuit sends a list of image signals in the sub-screen to a list of LEDs on the sub-screen to ensure that a list of LEDs are displayed at the same time; and the display of the images of the whole sub-screen is realized by scanning different lists in sequence. A PC machine is connected with a PCI-E bridge, an electro-optic 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 orderly. The distribution field programmable gate array is connected with a multi-path gating apparatus module, a high power apparatus module and the LED screen. The invention realizes the high speed transmission, storage, processing and display of mass data, improves the refresh rate of the image greatly as well as the brightness and resolution 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 driving method and 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 i...

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
