Only Insiders Know These Information Gaps in LED Display Purchase – Take a Look!

Meaning Pixel pitch refers to the distance between the centers of two adjacent pixel points in an LED display, usually measured in millimeters (mm). For example, P2.5 means the pixel pitch is 2.5mm.

Impact Pixel pitch directly affects the display's clarity and optimal viewing distance. Generally speaking, the smaller the pixel pitch, the more pixels per unit area, the higher the resolution, and the clearer the image. However, displays with smaller pixel pitches are relatively more expensive. For instance, P1.2 displays are suitable for close-range viewing (e.g., showing high-definition detailed content in small conference rooms) but have higher costs; while P4 and P5 displays have larger pixel pitches, making them suitable for long-distance viewing in large venues such as the screens above stadium spectator stands.

Information Gap Some merchants may not take the initiative to mention the impact of pixel pitch on viewing effects. If consumers are not aware of this, they may buy displays that fail to meet their expected viewing distance and clarity requirements. For example, if a consumer wants to use the display indoors at close range but buys a product with a large pixel pitch, it will result in a blurry image.

Meaning Refresh rate is the number of times the screen image is refreshed per second on an LED display, measured in Hertz (Hz). Common refresh rates include 30Hz, 60Hz, etc.

Impact A higher refresh rate can make the image smoother and reduce flicker and motion blur. This advantage is particularly obvious when playing dynamic videos or fast-moving images. For example, when playing sports games or action movies, a 120Hz refresh rate display can clearly show athletes' fast movements or high-speed cars without blurriness.

Information Gap Some merchants may manipulate refresh rates by passing off low refresh rates as high ones. Or they may fail to clearly mention the refresh rate in product introductions. If consumers do not pay attention, they may buy displays with low refresh rates, leading to poor viewing experience.

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

High contrast ratio can make the image colors more vivid, blacks deeper, and whites brighter, thereby enhancing the image's layering and visual impact. When displaying night scenes or dark-toned scenes in pictures or videos, a high-contrast display can better show details. For example, when playing dark scenes in a suspense movie, a high-contrast display allows the audience to clearly see clues in the shadows. Information Gap

Merchants may exaggerate contrast ratio values or use different testing methods to obtain falsely high contrast data. If consumers do not understand the real testing methods and standards for contrast ratio, they are easily misled into thinking they have purchased high-quality products with high contrast ratios, but the actual use effect is greatly reduced.
