What are the categories of LED display

full color display screen: Red, green and blue three primary colors.
256 gray level full color display screen can display more than 16 million colors.
256 gray level full color display screen can display more than 16 million colorsAccording to the display device classification, LED digital display: the display device is a 7-segment code nixie tube.
it is suitable for making clock screen, interest rate screen, etc., and electronic display for displaying numbers.
LED dot matrix graphic display: the display device is a dot matrix display module composed of many evenly arranged light-emitting diodes.
it is suitable for playing text, interest rate screen, etc Image information.
LED video display: the display device is composed of many light-emitting diodes.
it can display various video files such as video, animation, etc.
the display device is composed of many light-emitting diodesClassified according to the use of occasions, the indoor display screen has a small luminous point.
general Φ 3mm-- Φ 8 mm, display area is generally several to more than ten square meters.
outdoor display: area is generally dozens of square meters to hundreds of square meters.
high brightness, can work in the sun, with wind, rain, water-proof functions.
the display screen is mainly used for outdoor displayClassification of indoor screens by diameter and spacing of light emitting points: Φ 3mm、 Φ 3.75mm、 Φ 5mm, outdoor screen (divided by spacing): PH10, pH12, ph14, PH16, PH20, ph25, ph31.25, ph37.5The display modes include static, horizontal scrolling, vertical scrolling and page turning.
a single module controls and drives 12 pieces of 8x8 lattice (up to 24 pieces).
a total of 16x48 lattice (or 32x48 lattice),Is a single MAX7219 (or PS7219, HD7279, ZLG7289 and 8279 similar LED display driver module) 12 times (or 24 times)! The "cascade" mode can be used to form any dot matrix large display screen.
the display effect is good.
the power consumption is small, and the cost is lower than that of MAX7219 circuit.
