Why Refresh Rate Matters?

In the context of LED displays, a higher refresh rate is particularly important for:

Reducing Flicker: At lower refresh rates, the human eye can perceive flickering, which can be uncomfortable or even cause eye strain over time. A higher refresh rate minimizes this flickering, producing a more stable image that’s easier on the eyes.

Improving Image Quality: For dynamic content, such as videos or animations, a higher refresh rate ensures smoother motion. This is crucial for maintaining clarity during fast-moving scenes and enhances the viewer’s experience.

Enhanced Performance in Captured Video: When recording video of an LED display (such as during televised events or with smartphones), a high refresh rate helps to prevent the appearance of rolling bands or flickering in the captured footage. This is vital for broadcasters and content creators who demand the highest quality in their productions.

How to increase the refresh rate of an LED display?

1. Evaluate Hardware and Driver IC Compatibility: First, check if the hardware or driver integrated circuit (IC) of your LED screen supports a higher refresh rate. If the current hardware or driver IC does not support the desired refresh rate, consider replacing them with models that do. Look for driver ICs that are known for supporting higher refresh rates.

2. Modify PCB Design or Change Scan Mode: Assess the printed circuit board (PCB) design and consider changing the scan mode to accommodate a higher refresh rate. Another option is to increase the number of driver ICs on the device. This can enhance the device’s processing capability and support for advanced functions, enabling a higher refresh rate.

3. Use High-Quality Driver ICs: Opt for premium and reliable driver ICs, such as ICN2153 and MBI5252, which are known for their performance and capability to support higher refresh rates. It’s crucial to have a good understanding of how these components work or to seek assistance from a professional or the product provider to install them correctly, as improper installation can damage the device.

4. Software Configuration: The software used with the LED screen can significantly impact its refresh rate. Some software may offer limited features and options, restricting the device’s potential for higher performance. Explore software options that allow for adjustments to the refresh rate or provide more advanced control over the display settings.

Comparision between LED Display Frame Rate and Fresh Rate.

The relationship and difference between the refresh rate and frame rate in the context of LED displays are important concepts in understanding how images are displayed and perceived.

Aspect Refresh Rate Frame Rate
Definition The number of times the display updates its illumination per second. The number of unique consecutive images (frames) displayed per second.
Measurement Measured in Hertz (Hz). Measured in frames per second (fps) or Hertz (Hz).
Purpose To maintain a stable and flicker-free image on the screen. To determine the smoothness of motion in video content.
Impact on View Affects the smoothness and comfort of viewing, particularly for static images or during motion. Directly affects the perception of motion; higher frame rates result in smoother motion.
Dependency A characteristic of the display hardware. A property of the content being displayed.
Optimal Use Higher refresh rates are preferred for reducing eye strain and achieving smoother image transitions. Higher frame rates are preferred for content with fast-moving images to make the motion appear more fluid.
Key Concern Ensuring the refresh rate is high enough to support the perceived smoothness of content. Ensuring the content’s frame rate is compatible with the display’s refresh rate for smooth playback.

How to increase the led display Frame rate to 120hz/240hz 

 To increase the frame rate of an LED display, you need to focus on improving several key configurations:

1. Processing Power of the Control Card: The control card is the core component of an LED display, responsible for processing signals and driving the pixels on the screen. Enhancing the processing speed and efficiency of the control card’s CPU can accelerate data processing and signal transmission, thereby increasing the frame rate.

2. Memory Capacity and Speed: The capacity and speed of memory on the control card directly impact the volume of data that can be quickly read and written, which is crucial for high frame rate displays. Enhancing the memory’s read-write speed and expanding its capacity can effectively increase the frame rate.

3. Data Transmission Interface: The speed of data transmission is another key factor in increasing frame rate. Utilizing high-speed data interfaces (such as HDMI 2.1, DP 1.4, etc.) can speed up the transmission of data from the source to the display, which is especially important for achieving high frame rates at high resolutions.

4. Parallel Processing Capability: Increasing the control card’s capability for parallel processing, i.e., the ability to process multiple signals or tasks simultaneously, can significantly increase the frame rate. This can be achieved by using multi-core processors or deploying multiple control cards in the system, which can distribute processing pressure and enhance overall processing speed.

5. Software and Algorithm Optimization: Optimization at the software level is also crucial, including but not limited to more efficient encoding/decoding algorithms, faster image processing algorithms, etc. Optimizing control software and driver programs can reduce processing delays and increase frame rate.

6. Display’s Own Refresh Rate: Although this is not directly related to the control card’s configuration, the physical refresh rate limit of the display itself also determines the upper limit of the frame rate. Even if the control card and other system configurations support a higher frame rate, the display’s own refresh capability must also keep up.

The key to increasing the frame rate of an LED display lies in the optimization of the overall system design, including hardware configuration upgrades and software-level optimizations. In practical applications, these factors should be balanced according to specific display requirements and budget to achieve the best display effects.

What is led display scan mode

Feb 17, 2023 | knowledgebase | 67 comments

led display scan mode

Scan mode, also called Scan rate or scanning driving, refers to the number of LED pixels that can be connected to a single driver IC. Each pixel is connected to a pin on the driver IC on the PCB board. The number of drivers required on a PCB board design to illuminate the pixel pitch determines the scan type. 

Two types of Scan modes:

1. Static scanning: 

Static scanning is to implement “point-to-point” control from the output of the driver IC to the pixels. 

2. Dynamic scanning:

Dynamic scanning is to implement “point-to-column” control from the output of the driver IC to the pixel points. 

Several factors, including the type and performance of the driver IC, refresh rate, grayscale, and pixel pitch directly influence the scan design.

scan mode led driving IC
A single driver IC has 16 pins output and can drive a maximum of 16 LED chips. In static drive mode, all LEDs on the LED module can be driven by the IC simultaneously, as illustrated in the following image.
scan rate of led screen

Static: A single-driver IC has 16 pins and can drive a maximum of 16 LED chips. In static drive mode, all LEDs on the LED module can be driven by the IC simultaneously, as illustrated in the following image.

1/2 Scan: In 1/2 scan mode, the IC drives a set of 1/2 LEDs on the module at a time, and subsequently switches to another set of 1/2 LEDs.

1/4 scan: 1/4 of LEDs on the module are driven by IC at one time, and next time there are other 1/4 LEDs that are driven.

Taking a 1/45 scan P1.875 design with the LED and driver IC on the same side as an example:

Module size:300×168.75mm; pixel resolution: 160×90=14,400 dots.

Each LED contains 3 color chips(1R1G1B), so there is a total of 14,400×3=43,200 colors in one led module.

with 1/45 scan driving mode. only 43,200/45 =960 colors are required to be lit up each time.

Since each Driving IC has 16 pins. so the total amount of Driving ICs required for one module is 960/16 = 60 pcs (2o pcs for Red color;20 pcs for Green Color;20 pcs for Blue color)

driving ic led display diagram visionpi

Why is Dynamic driving mode essential? 

A static driver design (P1.875) would require  2700 16-channel driver ICs and current setting resistors. That will lead to an increased number of PCB layers and costs, on the other hand, the brightness is much higher but the current is also too high. 

A dynamic driving mode design utilizes a single driver IC to activate more LEDs, conserving space on the PCB board and optimizing the budget and driver IC’s layout. However, when aiming for high image quality, there is a trade-off between high grayscale and high scan rate. As a result, a smaller pitch necessitates more time-multiplexing in the design. Typically, P2.5 displays implement a 1:16 time-multiplexing design, whereas displays with a pitch of 2 mm and below require time-multiplexing above 1:16.

Scan Mode,brightness,refresh rate and grey level

The lower the scan rate, the better the performance and the more expensive it will be.

  • Brightness

    The higher the scan the more LED pixels one driver needs to light at once. The brightness is doubled compared to a 1/2 scan, and with a 1/4 scan, the brightness doubles compared to a 1/8 scan. Nevertheless, adjusting the software through experimentation can reduce the brightness if high brightness is not essential. in some cases, the outdoor fine pixel pitch led display requires a super high brightness of 6000-10000nits, the high brightness gold wire LED can provide the required brightness in a lower scan mode (1/13scan 1/16 scan)

high brigtness outdoor led display visionpi

  • Power Consumption 

    Increasing the scan rate results in higher power consumption. A simple formula accurately reflects this correlation: for instance, a 1/8 scan consumes twice as much power as a 1/16 scan. The current is also a limiting factor. In the future, factories may reduce current, thereby diminishing both power consumption and brightness. commom cathode technolgy can reduce the power consumption without sacrifce the brightness.

energy saving led display visionpi

  • Refresh Rate

    The refresh rate of a screen is indicated in hertz (Hz) and signifies how frequently the image is updated per second. When the number of scan lines is doubled, the time required to illuminate all LEDs will increase twofold, and the refresh rate will be halved. Thus, increasing the number of time-multiplexing in a design makes it more challenging to achieve a high refresh rate. Decreasing the scan rate will reduce the refresh rate and vice versa. However, the PCB design and type of driver IC also influence the refresh rate. Incorporating a driver IC with an embedded SRAM can enhance the refresh rate by decreasing the time required to transmit grayscale data. If the driver IC supports GCLK multiplier technology, the refresh rate must be doubled.

Choosing a scan mode for LED display is a crucial decision that depends on various factors, such as brightness, power, refresh rate and cost. A higher scan mode is not always better, nor is a lower one. The goal is to design an optimal LED screen that meets the desired specifications.
