Only insiders know the information gap when buying LED display screens, come and take a look

Meaning: Pixel pitch refers to the distance between the centers of two adjacent pixels in the LED display screen, usually in millimeters (mm). For example, P2.5 means that the pixel pitch is 2.5mm. Impact: Pixel pitch directly affects the clarity and optimal viewing distance of the display screen. Generally speaking, the smaller the pixel pitch, the more pixels per unit area, the higher the resolution, and the clearer the picture. But at the same time, the price of display screens with small pixel pitch is relatively high. For example, P1.2 display screens are suitable for close viewing, such as displaying high-definition details in a small conference room, but the cost is high; while P4 and P5 display screens have larger pixel pitches and are suitable for large venues for long-distance viewing, such as display screens above the stadium seats.

Information gap: Some merchants may not actively mention the impact of pixel pitch on viewing effects. If consumers do not understand this, they may buy display screens that do not meet the expected viewing distance and clarity requirements. For example, if consumers want to use a display screen indoors at a close distance, but buy a product with a larger pixel pitch, the picture will be blurred.

Meaning: Refresh rate refers to the number of times the LED display screen is refreshed per second, in Hertz (Hz). Common refresh rates are 30Hz, 60Hz, etc.

Impact: A higher refresh rate can make the picture smoother and reduce flickering and smearing. Especially when playing dynamic videos or fast-moving images, the advantages of high refresh rates are more obvious. For example, when playing sports games or action movies, a 120Hz refresh rate display can clearly show the fast movements of athletes or high-speed cars without blurring. Information gap: Some merchants may make a fuss about the refresh rate and use a lower refresh rate to pretend to be a high refresh rate product. Or if the refresh rate is not clearly mentioned in the product introduction, consumers may buy a display with a lower refresh rate if they are not careful, resulting in a poor viewing experience.

Meaning: Contrast refers to the brightness ratio between the brightest and darkest areas of the display. For example, a contrast ratio of 1000:1 means that the brightness of the brightest area is 1000 times that of the darkest area.

Impact: High contrast can make the colors of the picture more vivid, the black deeper, and the white brighter, thereby enhancing the layering and visual impact of the picture. When showing night scenes or dark scenes in pictures or videos, high-contrast displays can better show details. For example, when playing a dark scene in a suspense movie, a high-contrast display allows the audience to clearly see clues in the shadows.

Information gap: Merchants may exaggerate the contrast value or use different testing methods to obtain inflated contrast data. If consumers do not understand the real testing methods and standards for contrast, they are easily misled into thinking that they have purchased high-contrast high-quality products, but the actual use effect is greatly reduced.
