What is LED IC Chip

LED IC chip is a very important component of LED screen, to a considerable extent, LED IC chip determines the upper limit of the visual presentation effect of the picture of LED screen.

Let’s go through this article together to understand the development of LED IC chip and the connection between IC chip and LED screen.

LED IC chip is equivalent to the brain of the LED screen, from receiving data, processing information, generating signals and controlling the current of the entire process is controlled by the LED IC chip, and ultimately let the LED screen light beads in accordance with the design to light up the formation of the ideal image.

LED lamp beads belong to the current characteristics of the device, so the brightness of the LED lamp beads will not change with the change of voltage, but with the change of current, in order to LED lamp beads brightness display stability, usually professional LED IC chip will be used to maintain the stability of the battery constant current source, to avoid the flicker of the LED screen.

The brightness of the LED bead is related to the amount of current flowing through it, and the color of the LED bead is related to the length of time the current is on. The shorter the current flow time, the lower the grayscale of the LED bead, the lower the saturation, and the lower the brightness.

Why LED IC chip is important for LED screen

The performance of the LED IC chip determines the picture quality of the LED screen.

The stronger the performance of the LED IC chip, the greater the advantages associated with the two, the following are the advantages that the LED IC chip can bring to the LED screen:

Brightness management: LED IC chips manage the brightness of LED screens by processing the amount of transmitted current, quickly adjusting to the expected brightness and maintaining stability.
Pixel control: LED IC chips control the color and brightness of the LED screen down to the individual pixel.
Improved Stability: The LED IC chip uses a constant current source, meaning that the IC chip will control the stability of the current during use, which is positive feedback for extending the life of the LED screen.
Refresh rate: When the refresh rate of LED screen is too low, it may lead to motion blur and screen flickering, therefore, choosing an LED IC chip that supports high refresh rate can effectively avoid these problems.

Color depth and grayscale management: LED IC chips have been able to control the color depth and grayscale level of LED lamp beads in a progressively more refined way, so that the LED screen playback screen colors are more vivid and vibrant.

Evolution of LED IC chips

In the early 1990s, LED display screen is still using constant voltage driver IC, at that time, the LED screen is mainly single-color and two-color.

In 1997, China’s first LED display dedicated IC chip appeared, from 16 levels of gray scale evolution to 8192 levels of gray scale, from 8-way drive evolution to 16-way drive, LED screen performance has produced a qualitative leap, and technicians found that the luminous characteristics of the LED lamp beads by the constant current to control will be more stable, the LED IC chip also from the constant voltage drive into a constant current drive.

Until now, LED IC chip is constant current driver chip, and JYLED has begun to launch part of the 48-channel LED IC chip.

What types of LED IC chips are available?

General Purpose Chip

General-purpose chips are not specially designed for LED screens, but the operation logic is similar to that of LED IC chips, which can be used for LED screens as well as other devices.

Specialized Chip

Dedicated chip refers to the LED light-emitting characteristics according to the specially designed chip, this dedicated chip is a constant current source chip, can provide stable current to the LED screen to eliminate LED screen flicker.

For LED screen applications in different industries, the dedicated IC chip will also add some special features, such as error detection, current control, current correction and so on.

LED IC chip performance indicators

LED IC chip is related to the LED screen refresh rate, gray scale, image quality, etc., initially, the technology is not developed enough, can not take into account the three indicators to do a good job, only to ensure that one or two indicators of the case of excellent performance at the expense of other indicators;

however, now with the development of technology, these issues have been resolved, high-quality LED IC chip, whether it is the refresh rate, gray scale or image quality, in practical applications have very good performance. In practical applications, have excellent performance.

LED IC chip and refresh rate of the relationship

LED IC chip is the basis for managing the refresh rate, the better the quality and performance of the IC chip, the higher the refresh rate of the LED screen can be realized, and the better the visual experience of the LED screen.

What is the LED display refresh rate?

LED screen refresh rate refers to the frequency of updating the image of LED display per second, which is measured in HZ. For example, an LED screen with a refresh rate of 480 HZ refreshes the screen image 480 times per second.

The better the LED IC chip performance, the higher the LED screen refresh rate. At present, the common refresh rate of LED screen is 480HZ ~ 960HZ, in some professional areas of high requirements for the refresh rate of the LED screen, the refresh rate can also reach 3840HZ or even higher.

High refresh rate and low refresh rate

Screen quality: low refresh rate LED screen has obvious flickering and motion blur, high refresh rate LED screen is smooth and flicker-free.
Practical application: low refresh rate LED screen is mostly used for static signage display, high refresh rate LED screen is used for performance, publicity, games and other video displays.

LED IC chip high-performance advantages

Silky smooth image transition: the better the LED IC chip performance, the higher the refresh rate, the smoother the image transition of the animation, the naked eye looks more natural.
Reduced flicker: the better the LED IC chip performance, the higher the refresh rate, the more stable the screen display, the refresh rate is low, the screen flicker will be very obvious, high refresh rate can be maximized to improve the screen flicker.

Benefits of using LED IC chips

Energy saving power supply

The energy-saving effect of the LED screen is a well-known thing, in addition to the LED lamp beads themselves when the light emitting high energy utilization, a high-quality IC chip can also make a great contribution to energy saving. Usually, LED IC chip will improve energy saving from two angles:

Reduce the constant current inflection voltage: LED IC chip can reduce the traditional 5V voltage to 3.8V voltage below, effectively reducing the constant current inflection voltage, to achieve the purpose of energy saving.
Reduce the driver IC voltage and current: JYLED has been making continuous efforts to update the technology and optimize the design of LED IC chip to reduce the IC chip’s operating voltage and current, and ultimately achieve the purpose of energy saving.

Outstanding integration

For the LED screen function demand is getting higher and higher, the LED IC chip needs to load more and more contents, in order to achieve the revolution of performance, the IC chip needs to have more excellent integration.

Currently, 48-channel LED IC chips have been introduced in the market, which pushes the performance and quality of IC chips to a new height.
