The main differences between Q1.5 and P1.5 LED modules lie in their naming conventions, pixel pitch, and possible unit board specifications and cabinet dimensions.
I. Naming Conventions
Q1.5 LED Modules: The Q series is usually a product model name customized by a specific LED display manufacturer to differentiate its products from those of other manufacturers. This naming convention is not universal but specific to one or more manufacturers.
P1.5: The P series represents the distance between two light-emitting points, i.e., the pixel pitch. P1.5 means that its pixel pitch is 1.5mm. This naming convention is common in the LED display industry, making it easy for users to intuitively understand the pixel density of the product.
II. Pixel Pitch
Although the pixel pitch of Q1.5 and P1.5 is close to 1.5mm, the specific value may differ. For example, some Q1.5 products may have an actual pixel pitch of 1.53mm (abbreviated as Q1.53), while P1.5 products may have an actual pixel pitch of 1.56mm. Although these differences are small, they can still have a certain impact on the display effect when used on a large scale.
III. Unit Board Specifications and Cabinet Dimensions
Q1.5 LED modules and P1.5 may also differ in unit board specifications and cabinet dimensions. Unit boards are the basic building blocks of LED displays, and their specifications and dimensions directly affect the assembly and splicing of the display. For example, the unit board of a Q1.53 small-pitch full-color screen might be a traditional 320 x 160 mm, while the unit board of a P1.56 small-pitch large-screen LED might be 200 x 150 mm.
Regarding cabinet dimensions, the die-cast aluminum cabinet of Q1.53 might be 640 x 480 mm, while the die-cast aluminum cabinet of P1.56 might be 400 x 300 mm. These differences may affect the ease of installation and use, as well as the overall appearance and stability of the display.
In summary, Q1.5 LED modules and P1.5 differ in naming conventions, pixel pitch, unit board specifications, and cabinet dimensions. For more detailed information, it is recommended to consult the relevant LED display manufacturer directly.
