Popularization of LED Display Driver Chips
For the LED display, the driver chip is its “brain”, which determines the performance, power consumption, display effect and so on of the LED display. Different from the human brain, whether the human brain is smart or not is born, but whether the “brain” used in the LED display is good or not is determined by the human being. Therefore, Qiangli Jucai decided to configure the industry’s top “brain” for Q Pro products. “Brain” – dynamic energy-saving high refresh PWM-SS driver chip.
Veteran drivers know that the automatic start-stop function of the car saves fuel, and the LED display with automatic start-stop function can save power!
Different from ordinary chips, the reason why the dynamic energy-saving high-speed PWM-SS driver chip dares to claim to be energy-saving is because it has many special functions, such as automatic start-stop technology. The LED display (such as Q Pro) equipped with this chip can automatically judge whether to enter the “sleep mode” according to the displayed content. Once it enters the “sleep mode”, the power consumption of the chip can be reduced by up to 80%, and it will automatically wake up when it is started. There will be a delay and will not affect the display effect.
Adjusting the power consumption according to the brightness is only a bit powerful, and playing text only consumes power for the text part, which is very powerful!
It is common sense that reducing the brightness of mobile phones can save power, but many people don’t know that LED displays can also achieve dynamic energy saving. The dynamic energy-saving high-brush PWM-SS chip can make the LED display adjust the power consumption according to the brightness. It can also achieve the power consumption of only the text part when playing text, and even adjust the power consumption according to the brightness of the color. Dynamic energy saving.
“Voltage” and “current” are knowledge points in physics textbooks, and “low voltage start-up” and “constant current drive” are the advantages of Q Pro.
You should not know that the inflection point voltage of commonly used constant current driver chips is 0.6-0.8V, and a 5V power supply is required to ensure the constant current state. However, the inflection point voltage of the PWM-SS driver chip is as low as 0.2-0.4V, and it can enter the constant current state with a 4.2V power supply, so Q Pro can reduce the power consumption of the LED display without sacrificing the display effect , Reduce heat generation and heat loss.
We have been emphasizing power saving and power saving, after all, it is not to help you save money!
Having said so many knowledge points about why PWM-SS driver chips can save energy, I still want to emphasize: saving electricity can save money! Compared with other ordinary LED display products on the market, the Powerful Jucai Q Pro equipped with PWM-SS driver chips can comprehensively save 30%~45% of power, and the service life of the LED display is as long as 10 years, you can calculate Under the same usage scenario, how much electricity can Q Pro save per year. So, do you still think Q Pro is more expensive?
Do not understand the concept of grayscale 14-15Bit? Then you have to know that the usual gray scale of TV is 8Bit!
“Gray level” refers to how many color levels each color has between the darkest and brightest colors, and the unit is the computer term Bit. The black-and-white image we are familiar with has a gray scale of 1Bit. Therefore, the higher the gray level, the more colors can be displayed, and the more delicate the picture will be. Dynamic energy-saving high-brush PWM-SS driver chip, the grayscale processing level can reach 14-15Bit, and the display effect can be imagined.
Refresh rate 3840Hz is a good screen standard? But that’s just the base standard for the Q Pro.
In the LED display industry, the refresh rate of 3840Hz has become the industry-recognized ultra-refresh standard. When most customers purchase high-refresh LED display products, they only need to look at the refresh rate number. In fact, if you have read this popular science, you will realize that the refresh rate is only one of the many criteria for judging the quality of LED displays. In addition, if the performance of the driver chip configured on the LED display is not enough, and the refresh rate is forced to increase, the driver chip will not be able to load, which will cause other problems such as “dropping frames” and “stuck”. Of course, needless to say, the PWM-SS driver chip can easily achieve a refresh rate of 3840Hz.
