A. Why do LEDs use such little power?

LEDs do not use a filament where a conductor is heated and light is created. Filament based lighting consumes more power than the light produced. LEDs produce very little amouns of heat and do not use filaments making them far more efficient in consumption and output.

B. Why JINGZHI enery-saving led display can save more than 21% power consumption.

1) Using super high luminous LED lamps.

Unique feature of the super high luminous lamps is more brilliant and less power dissipation. For instance, when lamps working under the same condition of high illumination, forward current running in the common sort of lamps is ≧16 mA, but for super high luminous lamps that we use, it is just ≦10 mA.

2) Using the power boxes with PFC.

In fact, when it transfers AC into DC, the efficiency is high up to 85%. Some other power boxes extensive used without the function of PFC, the transferring efficiency is just close to 60%~70%. The difference turns to be 15% power consumption.

3) Adopting to multiple controlling technique.

We use temperature control, brightness control, drive control, etc, to make our LED displays adaptive and environment-friendly. The methods can save the power consumption in the range of 5% to 8%. The capacity of adaptation hints not only saving power consumption, but also more convenient and more environmental protection.

C. What are Pixel Pitch, Pixel Density, LED QTY, and Pixel Configuration?

Pixel Pitch is the distance between neighboring pixels.

Pixel Density is the quantity of pixel per square meter.

LED QTY is the quantity of LED lamps per square.

Pixel configuration is the description of the consistence of a pixel, for instance, we use 1 red lamp, 1 green lamp, 1 blue lamp to compose a pixel, the pixel configuration is 1R1G1B.

D. What is viewing angle?

Viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. It includes horizontal viewing angle and vertical viewing angle.

E. What about red or amber LED signs versus full color LED signs?

Monochrome (red or amber) LED signs have represented a strong advertising value for nearly 10 years. Monochrome displays are the right selection for some budgets. They are a proven way to get attention and have been the standard in results for years. But if you want to display glamour shots of your products, play video displays and take advantage of other advertising tactics previously only available on TV and the internet, you might want to consider a color led sign.

F. I see many places apply the remote led signs, they change message only simple by remote controller, How about this kind sign?

Yes, this is great tread nowadays, Jingzhi remote led sign use remote controller to program message, no need to connect computer, no other additional cost, just simple to press the remote controller buttons to edit. And also, Jingzhi remote led display support display real time, date, week, day, you can set the display period during the day to save energy.

G. I like your led car display, but I don’t know which model suitable for me?

Don’t worry, you can get professional suggestion from Jingzhi, we produce the voltage from 9V to 36V, our different sizes and colors led car displays can meet your various demand. And also, you’ll get most cost-efficient led car displays base on our value suggestion.
