The invention discloses a novel main control chip and a digital display screen with the chip, and relates to the technical field of display chip structures. The novel main control chip comprises a PCBand a display module, wherein the display module is arranged on the PCB and used for controlling related logic displayed by the display module to be printed and distributed on the PCB and / or the display module, so that the processing difficulty of the PCB is reduced. According to the invention, by adopting the form of integrating the digital screen and the main control chip, two independent modules are combined into a whole, so that the occupied space is small, and the expansibility is high; by the adoption of the mode, the main control chip directly drives the constant-current LED chip, so that the operation is simple and efficient, and other load functions can be integrated; all light sources adopt patch RGB three-color LED lamps, and a full-automatic high-speed chip mounter is used foroperation, so that the assembly speed is greatly increased, and the reliability is also greatly improved; and a constant-current LED driving chip is adopted, the RGB combination proportion is accurately configured, any color can be blended, and the requirements of various display effects are met.
Description
technical field [0001] The invention relates to the technical field of display chip structures, in particular to a novel main control chip and a digital display screen with the chip. Background technique [0002] The traditional nixie tubes use the display module and the main control chip to separate the structure, the structure is complex, the integration is low, the space is large, and the traditional nixie tubes use plug-in LEDs. The processing process is complicated and the stability is poor. Traditional digital tubes use monochrome display or multiple colored LEDs. [0003] Such as figure 1 As shown, the main control chip that is traditionally arranged separately is a PCB board 1 and a display module 2 , and the PCB board 1 is connected to the display module 2 through a connecting wire. This method needs to put all the logic of the display on the main control PCB board, and the chip processing is difficult. Contents of the invention [0004] The technical problem t...
