Q:What is the difference between LED digital tube and LCD display?

Digital tube in the MCU, generally only digital display, of course there is a special part of digital tube display, can display date; LCD can realize digital tube can not be achieved, the Chinese characters, special symbols, as long as we write LCD to the corresponding ASC2 code, you can let LCD display the corresponding information.

Q:LED digital tube lighting can use solar power generation system

Can achieve color, colorful, jumping, chasing, flowing water, gray gradient, and synchronous scanning, running, stacking, trailing, pulling and closing, color elegant, text pattern and novelty beautiful full color changing effect,

Q:Some Dan micro light ghosting adjacent LED

Open position display, send section code, delay 0.2~1ms, pass display. Open the next one....The most effective way to prevent ghosting

Q:LED digital tube internal control six paragraph what do you mean?

A digital tube displayed by a single seven segment can display all the digital data of 0 - 9 according to the different conduction and cut-off of an external numerical control circuit. After a plurality of such digital tubes are combined, the counting display and the clock display can be formed...... And so on different digital displays. The six section of digital tube can only display a certain number, only the full display and shutdown of the two states, so the control circuit is relatively simple.

Q:Classification of LED digital tubes

Divided according to control mode: divided into internal control method (internal microcontroller, electrify automatic color change) and external control (need external controller to change color).

Q:Structure of digital tube

Led Displays Segment (LED digital tube) is composed of a number of light-emitting diodes packaged together to form a "8" font device, the lead has been completed in the internal connection, only to draw their respective strokes, common electrodes.

Q:Two LED digital tube pin number and name, use

Static display driver:Static drive is also called DC drive. Static drive refers to each digital tube of each segment by a microcontroller I/O port for driving, or use such as BCD code two - decimal injector drive. The advantages of static drive is simple programming, high brightness display, the disadvantage is occupied by I/O port, such as drive 5 digital tube static display is 5 x 8=40 I/O port to drive, you know a 89S51 microcontroller I/O ports available to 32. Therefore, the driver must be added to drive in practical application, which increases the complexity of the hardware circuit.

Q:LED digital tube needs the drive current, the monolithic integrated circuit can not satisfy. Not necessarily the triode, you can add drag resistors and so on...

Add triode can play a buffer and isolation, so that the microcontroller work more stable and reliable.

Q:Brief introduction of LED digital tube display principle

Classification: there are two kinds of common cathode and common anode. Display principle: to make certain segments lit, while others are not bright, you can display 0---9, A---F and other fonts.

Q:Nixietube why use PNP to drive?

The LED digital tube consists of a plurality of light-emitting diodes packaged together to form a "8" type device, and the leads are already connected internally to draw only their respective strokes, common electrodes. The nixie tube is actually made up of seven light-emitting tubes, consisting of 8 figures, plus 8 decimal points. These segments are represented by letters a, B, C, D, e, F, G, and dp.
