Dot-matrix Display can be used in many aspects,like:
Display in subway station;
display in bank,supermarket,school;
information board in hospital;
automotive advertising screen;
electric gate information screen and so on.
Products in photo album are part of main products in my company.And we also can
manufacture other model according to the requirements from customers.
Looking forward to your inquiry!
- Q:My breathing lantern flashes, dot matrix is 8*8., and the model is STC89C52 microcontroller
- Dot matrix, I think it should be modified by scanning the delay to achieve respiratory effects.
- Q:Why are the pixel sizes (LED) of the LED dot matrix module and the LED dot matrix display so large? Only 3.0mm, 3.7mm, 5.0mm, in the big diameter pixel resolution and pixel density is very low, in view of a strong sense of particle, why not make the pixel diameter small? For example, 1mm below, so that the unit area of pixel density is very high, how to solve? What is a single LED dot matrix module?...
- If the matrix module is broken, it will be changed. Small is to save maintenance costs. Also, it's easy to assemble.
- Q:I would like to ask 24 feet of two-color LED dot matrix working principle and circuit diagram
- It's about putting 64 LED in 8 rows and 8 columns. One LED has two feet. This one should know. Then, put one foot of each line together. (either the anode, or the negative pole, should be unified), and then draw a line out of the line as a drive line, there are 8 such lines. Then, each of the columns is not connected to the foot, followed by columns, but also lead a line out.
- Q:Where is the difference between a LED dot matrix screen and an ordinary LED display?
- LED dot matrix screen and LED screen is different: LED dot matrix screen brightness is relatively low. LED dot matrix screen in LED (or light) are encapsulated into one module, generally 8*8 lamp as a module, and the LED display module is a minimum in the display unit, comprising a circuit board, LED, pan, mask. Usually a number of modules to form a box (generally box length, width of not more than 1M), and then installed by the box into the customer needs LED display.
- Q:I have a smile LED dot matrix screen, is the reality of man kind, composed of small pieces of a total of 32 fast to form a dot matrix LED screen is welded on the circuit board, the circuit board at both ends of each of a 16 pin interface is the LED lattice screen should buy what kind of driver to control it? Thank you
- If you have 32 74HC595, you can have two colors, which can show red, green and yellow colors.It depends on how many boards you have and what you want to control with serial ports or network ports. Serial port cheaper. The net mouth is the cheapest 140 yuan.
- Q:Advantages and disadvantages of LED dot matrix display screen?
- The price is low, the quality is average (because the market is super mature, a casual person can make a piece of it himself)The disadvantage is quality, it is also eliminated products,
- Q:This is my modern electronic design topic, need to use the digital electronic technology knowledge to do, cannot use the monolithic integrated circuit or the PC machine. I hope you can tell me which chips and what devices to use, and so I'd like to tell you the whole idea. thank you very much indeed
- When A, B has a high level, another is allowed to input data, and the rising edge under the action of determining Q0 status in CLK, that when the CLK of a rising edge, a data shift, when after the eight rising after the input of eight bit data and line the output from the output end of the QA-QH.
- Q:How to use C language to achieve LED dot matrix display character movement
- It's not that the word is actually moving, but the image is different every time, and it shows 16 times continuously.
- Q:I used two pieces of 164 to light 8*8LED, dynamic scanning, the bright part of the light, the light should not be bright, please ask the teacher is the circuit problem or program problems? Because how to solve? Thank you
- Is a procedural problem, this phenomenon is commonly known as ghosting,
- Q:After my circuit is connected by PROTEUS, the interface between 74HC373 and 74LS138 doesn't know how to connect to the dot matrix.I picked up a few and tried, the lights were all lined up.Check on the Internet, it seems to be connected to the transistor and resistor limit flow what.
- No, you take the data directly from 373, and 138 should be ok. I use 595 to do the line input.
