LED Displays : 4 Things to consider

May 30, 2018

1. ENVIRONMENTS

 

INDOOR ENVIRONMENTS

 

 

In the production process, the single LED module is used as base unit, by combining each panel into size required.

 

 

OUTDOOR ENVIRONMENTS

 

 

In the production process, starting by encapsulating the light emitting 'die' into a single light emitting diode, also known as 'single lighting'. Generally, a reflector having a light collecting effect is used to increase the brightness; a plurality of LED single lights are packaged into a pixel module. The pixel module then forms a dot matrix display unit box, according to requirements. The box is water-proof and anti-fog to sustain in outdoor environments.

 

 

SEMI-OUTDOOR

 

 

The semi-outdoor screen is located between the outdoors and indoors, and it has higher luminance. The screen has higher degree of sealing, hence it is generally installed under the eaves or partially in the window.

 

 

 

2.  COLORS

 

MONO COLOUR

Single colour for each pixel. Red colour are usually in demand as it has higher luminous efficiency therefore having greater brightness.

 

 

DUAL COLOURS

 

 

Each pixel has two primary colour of red and green. Yellow can be superimposed, and in the case of grayscale control. different grey colours can be combined by varying the different grey levels of red and green.

 

 

RGB FULL COLOURS

 

Each pixel consist of three primary colour (red, green,blue). In the case of greyscale control, the colour of the natural environment can be well adjusted by combining the different greyscale of red, green and blue colour.

 

 

3. FUNCTIONS

According to various functions of the screen, the LED display are divided into four types: bar screen, graphic screen, video screen and digital mixed screen.

 

 

BAR SCREEN SERIES

These bar-liked structured display screens are mainly used for display texts. It can be input by remote control or connecting online with computer to send information to the text bar. It also works when offline.

 

 

GRAPHIC SCREEN SERIES

 

These displays are mainly used for text and graphics, generally without greyscale control. It enters information by communicating with the computer. A single computer is able to control multiple screens and can be displayed offline.

 

 

VIDEO SCREEN SERIES

 

 

These screens has a one-to-one mapping relationship with the pixels of the control computer monitor. There are 256 levels of greyscale control, so its performance is extremely rich. With multimedia card, the video screen is also able to play video signals. The open screen is good, there is no restriction on the operating system, the software is not limited, and it can reflect the display of the computer monitor in real time.

 

 

 

DIGIAL MIXING SCREEN SERIES

Digital screens are widely used on stock exchange market indicators, bank exchange rates, interest rates, hotel price list, etc. In most cases, bar screens are installed on digital screens to display greetings, notices, advertisements, etc. It also supports remote control input.

 

 

 

 

4. SHAPE 

Beside common flat screens, there are curved screens such as inner or outer L-shaped screens, arcs and circles.
