resolution for TV

With the advancement of modern technology, high-definition videos have become an indispensable part of our daily lives.

However, do you understand the differences and significance of high-definition videos with different resolutions?

This article will discuss with you the concepts, characteristics, and application scenarios of 720p, 1080p, and 4K resolutions.

if u have some questions, just free to free to contract us, tell us about your project. 

different between resolution

What is resolution?

Simply put, resolution is composed of pixels, which refers to how many pixels there are in 1 inch.

When the image size is the same, the higher the resolution, the more pixels, and the finer and more delicate the display effect.

For example, 1080P means there are 1920*1080 pixels in one inch, while 24 inches is 1920*1080*24

 

Is higher resolution better?

In a fixed size, the larger the resolution, the clearer it is, but if the sizes are different, this is not necessarily the case.

The resolution does not represent video quality, which is determined by many factors. The higher the resolution, the larger the video post-production space will be, but the higher the resolution, the higher the requirements will be placed on the equipment, so the appropriate resolution is the best.

 

What does P mean?

"P" means Progressive, which means progressive scanning. The number of P indicates how many rows of pixels there are vertically.

For example: 720P means there are 720 rows of pixels vertically, and 1080P means there are 1080 rows of pixels vertically.

As the resolution becomes larger and larger, we begin to use the "K" value to represent it. For example, 2160P started to be called 4K, but some people still call it 2160P.

different between resolution on screen

720P

720p is the starting point for high-definition video, also known as "Standard HD".

It has a resolution of 1280x720 pixels, with 720 rows of pixels both horizontally and vertically.

720p provides relatively high image quality, making visual effects clearer and more detailed.

This resolution is suitable for small-screen devices such as smartphones, tablets, and videos recorded by some cameras. 720p has a relatively small file size and is suitable for streaming over the Internet.

1080P

1080p is currently the most common high-definition video resolution, also known as "Full HD".

It has a resolution of 1920x1080 pixels, with 1080 rows of pixels both horizontally and vertically. Compared to 720p, 1080p provides higher image quality and more realistic visual effects.

This makes 1080p suitable for viewing on larger screens such as TVs, computer monitors, and projectors.

At the same time, 1080p is also a common resolution used in many video games and movie productions, allowing users to obtain a more immersive viewing experience.

4K

4K is currently the highest consumer-grade high-definition video resolution, also known as "Ultra HD" (Ultra HD).

It has a resolution of 3840x2160 pixels, providing 2160 rows of pixels both horizontally and vertically. 4K resolution has extremely high pixel density, making images sharper, more detailed, and more realistic.

This resolution is suitable for large-screen equipment such as large televisions and cinemas, as well as in professional film and television production.

4K video can show more details, allowing viewers to experience a more realistic picture performance, while also providing greater flexibility for post-production.

What is a receiving card?

In electronic equipment, a receiving card refers to a device that receives external signals and decodes them.

Receiving cards are usually used in LED displays, digital radio and television systems, electronic signboards.

To receive external signals and convert them into the format required by the display or device.

 

Working principle of receiving card

The working principle of the receiving card can be summarized into two steps: decoding and driving display.

Decoding is to convert external signals into a format that can be recognized by the computer, and driving display is to convert the signals output by the computer into the signals required by the LED display.

Specifically, the receiving card converts the signal into a format suitable for the television or display screen by receiving serial data or parallel data.

During the decoding process, the receiving card will process contrast, brightness, chroma and other aspects to convert the original signal into an image that is more in line with human vision.

Another key function of the receiving card is to drive the display.

By converting the digital signal output by the computer into an analog signal that matches the display screen, the receiving card can convert the digital signal into the electrical signal required by the display screen, thereby realizing the normal operation of the display screen.

 

Application of receiving card on LED display

Receiving cards are widely used in LED displays. Generally speaking, LED displays are divided into many modules, and each module requires a receiving card to receive, decode signals and control the display.

These receiving cards need to be connected to the control card of the LED display through data lines.

In the application of LED display screens, the performance of the receiving card has an important impact on the display effect.

High-performance receiving cards can achieve faster signal conversion and more precise drive control, thereby achieving higher-quality image display effects.

 

Application of receiving cards in radio and television systems

Similar to LED displays, equipment in broadcast and television systems also need to receive input signals and decode them.

The application of receiving cards in radio and television systems is to convert input signals into identifiable digital signals, then encode and encrypt the digital signals, and finally convert the digital signals into analog signals for playback.

LED Receiving Card

How to choose a good receiving card?

The resolution of the receiving card

The resolution of the receiving card refers to the maximum number of display pixels it can support, usually expressed in terms of the number of horizontal pixels and the number of vertical pixels.

The resolution determines the display effect of the LED display. A higher resolution can present clearer and more delicate images.

 

Brightness adjustment range of the receiving card

The brightness adjustment range of the LED receiving card determines the height adjustment ability of the LED display screen in different environments.

The larger height adjustment range allows the LED display to display a clear and bright picture in a sunny outdoor environment, while in a dark environment it can be adjusted to a lower brightness to avoid dazzling light.

 

Color processing capabilities of the receiving card

Color processing capability refers to the expressiveness and restoration of color by the LED receiving card.

Better color processing capabilities allow the display to present more realistic and vivid colors, making images more realistic.

 

Refresh frequency of receiving card

The refresh frequency refers to the number of times the LED display screen is refreshed per second, expressed in Hertz (HZ).

A higher refresh frequency can make the image smoother, reduce flickering and smearing, and improve the display effect.

 

iSEMC's LED video wall has receiving cards suitable for each different model type, which can better display images and maintain stability.

iSEMC LED Panel

Grayscale of receiving card

The gray level refers to the gray level that the LED receiving card can display.

The higher the gray level, the richer the color levels of the displayed image and the smoother the color transition.

Common grayscale levels include 8-bit, 12-bit, 14-bit, etc. Among them, the 12-bit grayscale can display 4096 levels of grayscale, and the color transition is more delicate.

 LED Wall with receiving card

Final thought

LED sending cards and receiving cards play a vital role in LED display systems.

Through the LED sending card, we can convert display content such as images and text into signals that the display screen can understand;

While the LED receiving card is responsible for receiving data signals and controlling the brightness and color of the LED lamp beads.

The collaborative work of these two components allows the LED display to present high-quality, uniform images and animation effects.

LED sending card and receiving card are essential and important parts to master the working principle of LED display.

In practical applications, it is necessary to select the appropriate sending card and receiving card according to specific needs to ensure the normal operation of the LED display.
