LED
display screen Classified according to the application site
Depending
on the application of different places, can be divided into indoor and outdoor
LED display two.
Indoor
LED Display screen
Mainly
used for indoor, in the production process is to first make Dot Matrix LED
grain (or digital), then by splicing modules for a certain size unit board,
according to user requirements, to show the board as the basic unit cell
splicing as the size of user needs. According to pixel size, indoor screen is
divided into φ3, φ3.75, φ5, φ8, φ10 and so on.
Outdoor
LED Display screen
Mainly
used for outdoor, in the production process begins with the light-emitting die
package into a single light-emitting diodes, known as single-lamp or LED lamp
beads, said, making room for the external screen of LED lights are generally
used with a condenser beads role reflector to increase the brightness; only by
the multi-LED lamp encapsulated in a single tube or single-pixel pixel modules,
or pixel by pixel control mode matrix composed of the display unit cabinet,
according to user needs and display the application site to a display unit
cabinet as the basic unit composed of the required size. Box should be sealed
in the design, in order to achieve the purpose of water fog, to adapt the
outdoor environment. According to the density of pixels, pixel density external
screen room is divided into 10000 points P10 / m, P12-point pixel density 6944
/ m, P16-point pixel density 3906 / m, P20 pixel density 2500 / m and other
specifications.
Classification
according to color
Used
according to the color of the LED lamp beads can be divided into single-color
LED display, dual-color, full-color three.
Single-color
Each
pixel only one color, the majority red, because red light more efficient,
higher brightness can also be green, it can be blending, that is part of the
red, some green, some yellow .

Full-color
Also
known as the three primary colors, each pixel has red, green and blue color,
gray scale control in a case of red, green and blue through the different
changes in gray, you can restore the natural color well, a combination of
16,777 , 216 colors.
According
to functional classification
Features
and functionality of the screen can be divided into the bar LED display screen,
graphics screen, Screen and Digital hybrid screen four.
Series
of screen
Type
of display used to display text, available remote control input, computer
on-line can also be used to send messages via computer. You can work offline.
Because many of these screens made of strip, so called of the screen.
Graphic
screen series
Such
LED display is mainly used for display text and graphics, usually no gray-scale
control. It is through communication with the computer input. Compared with the
bar screen, graphic display screen has the advantage of extensive font font,
and display graphics, compared with Screen, graphic screen of the biggest
advantages is a computer can control multiple screens, and can be off-line
display.
Series
hybrid LED screen
Screen
is the cheapest digital LED display, wide display for the Stock Exchange stock
quotes, bank exchange rates, interest rates show a variety of price lists and
so on. In most cases, installation of the digital screen to display the Welcome
screen, notice, advertisement, etc. Support for remote control input.
LED
Screen Series
Type
of LED display screen pixel monitor and control computer was one to one pixel
mapping, a 256-level grayscale control, so its expression is extremely rich,
multimedia card configuration, and the screen can also play video. Open Screen
is good, there is no restriction on the operating system, software, and no
limit to reflect real-time computer monitor's display.
