With the rapid development of science and technology, LED display technology is gradually mature, with clear picture quality, low power consumption, high brightness, long life and other advantages, has been widely used in the world. In recent years, the continuous development of Internet technology, in the XR studio, live broadcasting with goods, outdoor advertising media, commercial display, stage interpretation, etc. There are led display, the following will be our minray engineers to introduce you to the led display in detail, so that you have a better understanding and awareness of led display.
What is an LED display and how does it work?
- LED Display (Light Emitting Diode Display) is a kind of electronic display device that utilizes each light emitting diode (LED) as an independent pixel to display images, videos and texts. It can be combined into any area size and any shape, and is widely used in outdoor advertising, stage performances, traffic instructions, commercial displays and other fields.
- The working principle of LED display: LED display consists of multiple LED modules, each module contains red (R), green (G), blue (B) three kinds of LED lamp beads and PWM driver chip, control signals, through the PWM constant current chip output current to the RGB, RGB through the combination of the three primary colors of the different ways, you can form a 65536 different colors, the control system receives video or image signals, adjust the brightness and color of each LED, so as to present a high-definition dynamic picture. The control system receives video or image signals and adjusts the brightness and color of each LED, thus presenting a high-definition moving picture.
What are the main types of Led displays?
1：According to the use environment of LED display
- Outdoor LED display: high brightness, waterproof and dustproof, suitable for outdoor plaza, open-air places.
- Indoor led display: high pixel density, suitable for close viewing, such as conference room, shopping mall advertising screen.
- Transparency LED display: high transmittance, no obstruction to any original building, suitable for shopping malls, glass curtain walls.
- Curved LED display: with a certain bending angle, it can be spliced with any creative shapes, suitable for commercial modeling creative display.
- Stage rental led display: is temporarily set up when used, the use of rental mode, usually used for performance activities, concerts, conferences and so on.
2. Classified by LED display technology
3. according to the led display dot pitch classification
- Small pitch led display (P1.0-P2.5): suitable for high-end conference room, command center, etc.
- Conventional led display (P2.5-P6): commonly used in commercial display, stage rental interpretation.
- Large spacing led display (P8 or above): mainly used for outdoor advertising, long-distance viewing.
4. according to the led display display mode classification
- Full color led display: combined by RGB with 65536 colors, it can replace LCD monitor and is suitable for HD video playback.
- Monochrome/dual color led display: single or dual color combined by R or RG, mainly used for text and simple graphic display, such as bus stop sign, bar screen, queuing call sign and so on.
What are the advantages of Led display?
- High brightness and clarity: with 5000-10000nit brightness, which can be adjusted arbitrarily, and can be displayed clearly under the strong light outdoors.
- High refresh rate: conventional refresh in 3840HZ, for stage photography refresh rate of 7680HZ.
- Energy saving and environmental protection: led uses a low-voltage DC power supply, brightness adjustment is more intelligent, more energy-saving and power saving than LCD display.
- Long life: LED lamp beads life of up to 100,000 hours or more.
- Seamless splicing: modular design can realize seamless splicing of large screen.
- Strong flexibility: different shapes and sizes can be customized to adapt to various installation environments.
What are the application scenarios of led display?
- Outdoor advertising: streetscape billboards, transportation hubs, digital signage, advertising billboards.
- Stage Interpretation Rental: corporate events, musical performances, public events, studios.
- Commercial Display: Bar & Club, Shopping Center, Restaurant, Boutique, 4S Store, Leisure & Entertainment.
- Corporate & Institutional: Schools, banks, conference rooms, government offices, hospitals, churches, stock exchanges, casino casinos.
How to choose your suitable led display?
- Determine the use: whether it is used in outdoor advertising, stage interpretation, or commercial display, or indoor small-pitch conference room.
- Choose the right pitch: the closer the viewing distance, the smaller the pixel pitch should be, usually we use the pitch P*2 to calculate the furthest distance you need to view.
- Budget planning: the initial estimate of the size of the area of the led display, combined with the size of the point pitch, to estimate the cost of accounting, small pitch LED screen led more, large resolution, high cost.
- Configuration selection: led display configuration requirements also determines the price of high and low, led display cost occupies the highest is led, and driver IC, we have a long-term strategic cooperation with OSRAM, Nichia, the cost is higher, but we can warranty more than 5 years.
Minray future R & D led display technology direction are those?
At present, our Minray R & D Department and the marketing department is also actively exploring the future development trend of led display, at present we are researching and developing products are:
- Outdoor small-pitch led display: our product planning for outdoor small-pitch is between P1.0-P2.5, with ultra-high definition, simple maintenance, strong stability and other characteristics.
- Stage leasing led display: 1: long time use, reduce the decay rate of led. 2: solve the stage leasing bump pain point, we have a strong thrust led lamp beads. 3: solve the led protective, more with the function of moisture-proof.
- Indoor small pitch: we use the technology of MIP, can make the whole screen more black, better consistency, higher color reproduction.
Summarize: the advantages and future development prospects of LED display
LED display has become an important part of modern display technology due to its excellent display effect and wide range of application scenarios. Whether it is outdoor advertising media, indoor commercial display, sports events or stage performances, LED display can provide a stunning visual experience. In the future, with the development of Micro LED and Mini LED technology, LED display will be more high-definition, energy-saving, and application scenes will be further expanded.
