LED outdoor display screens and outdoor LCD advertising machines have their own advantages.
LED display screens have high brightness (general brightness above 5500cd), are suitable for bad weather, and have various advertising forms and fast updates.
LCD advertising machines are characterized by high-quality image and text display, low power consumption, and low noise, and are more suitable for crowded areas. When choosing, you need to weigh the needs of high brightness and economy.
LED outdoor display screen
1. Basic features
- Area and size: The area of LED outdoor display screens usually ranges from tens of square meters to hundreds of square meters or even larger.
- Brightness and viewing angle: LED outdoor display screens have high brightness and can display clearly even in the sun. Its viewing angle is large and can be viewed from multiple angles.
- Weather resistance: It has certain windproof, rainproof, and waterproof functions, suitable for outdoor environments.
2. Application scenarios
- Outdoor advertising: Mainly used for outdoor billboards, commercial areas, squares, etc.
- Public information display: Information release in public places such as stations, airports, and docks.
3. Technical principle
- LED screen is a new type of imaging electronic device made of light-emitting diodes arranged in sequence. Its core part is a chip composed of p-type semiconductor and n-type semiconductor. There is a transition layer between p-type semiconductor and n-type semiconductor, which is called p-n junction.
Outdoor LCD Advertising Machine
1. Basic features
- Display quality: LCD advertising machine uses high-resolution liquid crystal display, with bright colors and delicate picture quality.
- Intelligent operation: Usually equipped with intelligent operating system, supporting multiple playback modes and timing functions.
2. Application scenarios
- Commercial places: such as hotels, commercial office buildings, shopping malls and supermarkets.
- Public transportation: such as subway stations, railway stations, airports, etc.
3. Technical principle
- LCD liquid crystal display is a liquid crystal placed between two parallel pieces of glass. The direction of the rod-shaped crystal molecules is controlled by whether the electricity is turned on or not, and the light is refracted to produce a picture.
Comparison between LED outdoor display and outdoor LCD advertising machine
1. Light-emitting principle
- LED is a light-emitting diode, which can emit light by itself.
- LCD emits light through a backlight module.
2. Brightness and contrast
- LEDs are usually brighter and can display better in strong light environments.
- LEDs usually have a higher contrast ratio and more vivid colors.
3. Weather resistance
- LED outdoor displays are more suitable for outdoor environments and are windproof, rainproof, and waterproof.
- LCD advertising machines require additional protection when used outdoors.
4. Energy consumption and lifespan
- LEDs are more energy-efficient and usually have a longer lifespan than LCDs.
5. Cost
- LEDs were more expensive in the early stages, but as technology develops, costs are gradually decreasing.
- LCDs are relatively cost-effective.
6. Applicable scenarios
- LED outdoor displays are more suitable for outdoor advertising, sports events, and other occasions that require high brightness and a wide viewing angle.
- LCD advertising machines are more suitable for indoor or semi-outdoor environments such as commercial venues and public transportation.
7. Maintenance and care
- The maintenance of LED outdoor displays is relatively simple, but attention should be paid to waterproofing and dustproofing.
- LCD advertising machines are easier to maintain when used indoors, but require additional protective measures when used outdoors.
FAQs
