The pixel pitch of the COB LED display is a key factor in its display effect, which determines the detail and clarity of the screen image.
Display screens of different sizes have different pixel pitches, ranging from as small as 0.9mm to as large as several millimeters. These small differences directly affect the audience’s perception and visual experience of the picture.
Overview of pixel pitch of COB LED display
COB (Chip On Board) LED display is a display that uses advanced packaging technology to directly package the LED chip on the PCB board.
Due to its small pixel pitch, high resolution, delicate picture, and bright colors, COB LED displays have been widely used in indoor and outdoor display fields. Pixel spacing is one of the important indicators for evaluating the performance of LED displays. It directly affects the resolution and clarity of the display.
Pixel pitch for different sizes and resolutions
P0.9
The pixel pitch is 0.9mm, the resolution is up to 1234×694, and the screen size is generally 60 inches. This kind of pixel pitch display screen has extremely high clarity and fineness, and is suitable for places that require extremely high display effects, such as high-end conference rooms, exhibition halls, etc.
P1.25
The pixel pitch is 1.25mm, the resolution is up to 768×768, and the screen size is generally 100 inches. This kind of pixel pitch display screen has high cost performance while maintaining high definition, and is suitable for most indoor places, such as shopping malls, hotels, etc.
P1.5
The pixel pitch is 1.5mm, the resolution is up to 640×640, and the screen size is generally 120 inches. This pixel pitch display screen has a larger screen size while maintaining a certain clarity, and is suitable for large indoor venues, such as theaters, stadiums, etc.
P2.5
The pixel pitch is 2.5mm, the resolution is up to 480×480 or 160000 dots/㎡, and the screen size is generally 100 inches. This pixel pitch display screen has high cost performance and moderate clarity, and is suitable for various indoor places, such as conference rooms, exhibition halls, stages, etc.
P3
The pixel pitch is 3mm, the resolution is up to 384×384 or 111111 dots/㎡, and the screen size is generally 100 inches. This kind of pixel pitch display screen has a larger screen size and lower cost while maintaining a certain clarity. It is suitable for places that do not have particularly high requirements for display effects, such as shopping malls and hotel lobbies.
The impact of pixel spacing on display effects
The smaller the pixel pitch, the higher the resolution of the display, the more delicate the picture, and the more natural the color transition. At the same time, the display with small pixel pitch can maintain high clarity when viewed at close range, without obvious graininess.
Therefore, for places where high-quality images or videos need to be displayed, such as high-end conference rooms, exhibition halls, stages, etc., it is recommended to choose COB LED displays with smaller pixel pitches.
However, pixel spacing is not the only factor that affects display performance. The brightness, contrast, color gamut and other parameters of the display will also affect the display effect. Therefore, when choosing a COB LED display, multiple factors need to be considered to ensure the best display effect.
Characteristics of various pixel pitches
P0.9 pixel pitch
This pixel pitch display has extremely high clarity and finesse, capable of presenting very detailed and realistic image effects. At the same time, because the pixel pitch is very small, the requirements for LED chips and packaging technology are also very high, so the cost is relatively high.
P1.25 pixel pitch
This kind of pixel pitch display screen has a high cost performance while maintaining high definition. It is suitable for most indoor places and can meet general display needs. At the same time, due to its moderate pixel pitch and relatively low requirements for LED chips and packaging technology, the cost is also relatively low.
P1.5 pixel pitch
This pixel pitch display allows for a larger screen size while maintaining a certain level of clarity. It is suitable for large indoor venues such as theaters, stadiums, etc. Due to its large pixel pitch and relatively low requirements on LED chips and packaging technology, the cost is also relatively low.
P2.5 pixel pitch
Displays with this pixel pitch offer good value for money and moderate clarity. It is suitable for various indoor places, such as conference rooms, exhibition halls, stages, etc. At the same time, due to its moderate pixel pitch and relatively low requirements for LED chips and packaging technology, the cost is also relatively low.
P3 pixel pitch
This pixel pitch display has a larger screen size and lower cost while maintaining a certain clarity. It is suitable for places that do not have particularly high requirements for display effects, such as shopping malls, hotel lobbies, etc. Due to its large pixel pitch and relatively low requirements on LED chips and packaging technology, the cost is also relatively low.
To sum up, the pixel pitch of COB LED display is one of the important factors affecting the display effect. When choosing a display screen, you need to choose the appropriate pixel pitch and resolution based on specific usage scenarios and needs.
At the same time, it is also necessary to comprehensively consider the brightness, contrast, color gamut and other parameters of the display screen as well as cost and other factors to make decisions.
