LED digital display screen

Abstract

The invention discloses an LED digital display screen, comprising a decimal point character block (2) and N 8-shaped character blocks (4), wherein the decimal point character block (2) can be detachably connected in series; the decimal point character block (2) comprises a PCB circuit board I (6) and an LED light I (1), wherein the PCB circuit board I (6) is connected to a character block outer frame I, and the LED light I (1) is inserted on the PCB circuit board I (6) and is connected with an LED light control circuit I which is arranged on the PCB circuit board I (6); each 8-shaped character block (4) comprises a PCB circuit board II (11) and an LED light II (3), wherein the PCB circuit board II (11) is connected to a character block outer frame II (10) and the LED light II (3) is divided into twenty-five LED field groups and is connected with an LED light control circuit II arranged on the PCB circuit board II (11); the character block outer frame I and the character block outer frame II (10) are detachably connected into a whole through a fixing strip (31). Each displayed number is an independent character block part, the character block parts can be freely combined to display number information, thereby being full of individualization for displayed number fonts.

Description

Technical field: [0001] The invention relates to a display screen for displaying various digital information, in particular to an LED digital display screen. Background technique: [0002] At present, LED digital display screens are widely used in all walks of life due to their high brightness, low operating voltage, low power consumption, and long service life. However, the existing LED digital display screens still exist in practical applications. The following defects: 1. Several numbers on the digital display screen are all displayed on or connected to the same circuit board. When it is necessary to increase or decrease the displayed numbers, the circuit has to be redesigned. The circuit structure on the board or re-purchase another type of digital display; 2. Each number on the digital display generally adopts a 7-segment control display method. In other words, each number consists of three horizontal fields and four When several of the 7 fields light up at the same ti...

Each number on the digital display generally adopts a 7-segment control display method. In other words, each number consists of three horizontal fields and four When several of the 7 fields light up at the same time, the corresponding numbers will be displayed. Although the 7-segment control display method makes the circuit structure of the digital display relatively simple, it The digital font displayed is relatively popular and rigid
