LED Display:

It is an electronic display composed of LED dot matrix. The content form is displayed in the context of the content form, animation, and real-time transition, which is displayed by clicking on the traffic light. Component display control is performed by a modular structure.

It is mainly divided into display module, control system and power system.

The display module is an array of LED light points to form screen lighting; The control system is to adjust the expansion of the area to convert the content displayed on the screen; The power system needs to convert the input voltage and current to meet the display.

The above content reference: Encyclopedia - LED display.

Due to its long outdoor operation time and large amount of outdoor full-color screen, the screen body pays great attention to the pursuit of the stability of the screen, good waterproof performance, good picture quality, large visual range, high brightness, energy saving and other characteristics.

To this end, we have done a series of work at Focus Technology:

1. Guarantee the stability of the screen body - control the production process, do 30 degrees Celsius to 65 degrees Celsius high and low temperature impact experiments, 48 hours of high temperature aging experiments, simulated transportation vibration experiments, etc., drive IC, power supply, plug-in parts and other components to select brand components, according to the utilization rate of 80 power supply, etc.;

2. Waterproof guarantee - use international brand LED special potting matte glue, and do IP65 protection water filling test on the front of the box used by the factory;

3. Picture quality assurance - according to the principle of three primary colors and the different attenuation curves of red, green and blue LEDs, the brightness of three-color LEDs is reasonably matched, and a screen uses a grade of LEDs; **Application of processor, application of single point correction system, etc.;

4. Viewing angle guarantee - select large viewing angle LED, and set the best viewing angle range of the screen body according to the amount of excitation in the application field; The application of outdoor three-in-one LED can make the upper and lower viewing angles of the display exceed 120 degrees;

5. Brightness guarantee - set the maximum brightness of the display screen (generally the brightness of 130 in normal use) according to the user's use site and the direction of the screen display, and the driving current of the LED is set to be less than 18

ma, the screen has been used for 2 years, and the brightness attenuation is less than 20;

6. Energy-saving guarantee - the automatic ambient brightness adjustment system is used to automatically change the brightness of the screen under different external brightness conditions.

LED full-color screen application range: mainly suitable for cultural squares, traffic arteries, stations and wharves, information centers, entertainment venues, shopping centers, commercial cities and other outdoor places of advertising, information release, news broadcasting, etc.

Indoor LED full color screen.

PH2, PH4, PH5, PH6, several models (the mainstream of the market is generally PH6 and.

Indoor LED full-color screen**: Indoor full-color screen is also divided into two styles, three-in-one and three-and-one**, with a gap of about 10,000 per square meter.

The die of the indoor full-color screen is also divided into domestic general chips (4 categories), domestic advanced chips (3 types), American advanced chips (2 types), and Japanese advanced chips (1 type). The highest grade is the original Japanese Nichia advanced chip (Class 1). On average, each square meter is about 10 times more expensive than the national shed collapse.

Outdoor LED full color screen.

PH10, PH12, PH16, PH20, PH25, several types of chain source French numbers (the mainstream of the market is generally PH12 and PH16).

Outdoor LED full-color screen**: The die of the outdoor full-color screen is also divided into domestic general chips (4 types), domestic advanced chips (3 types), American advanced chips (2 types), and Japanese advanced chips (1 type). The highest grade is the original Japanese Nichia advanced chip (Class 1).

On average, each square meter is 1 to twice more expensive than domestic ones.
