Based on the receiving card design and the maximum carrying capacity, the number of receiving cards for various LED screen lengths and widths is different. A P10 LED display, the required length of 20 meters, the height of 10 meters. Calculate how many modules used: P10 display unit board size is: 32cm * 16cm; [...]
The area of a large LED display is not a single structure, it is made of a number of cabinets splicing. Cabinets in the display play an important role, both to protect the internal components, but also to split the LED display. And makes it easy to transport, maintain, etc. Below let's find out [...]
In-vehicle LED display is to use led technology, GSM/GPRS technology, low-temperature technology, anti-static technology, anti-interference technology, in-vehicle electronic technology, etc. to display information products on mobile vehicles. As it is based on the mobile bus as the medium, it can be widely circulated in many places and bring great advertising promotion effect and is [...]
First of all, we need to understand what is the "water ripple" on the display? Its scientific name is also known as: "moire". When we use a digital camera to shoot the scene, if there is a dense texture, often appear inexplicable water wave-like stripes. This is moire. Simply put, moire is a manifestation [...]
Definition of LED display viewing angle Viewing angle refers to the angle at which the user can clearly observe all the contents on the screen from different directions. Viewing angle can also be understood as the maximum or minimum angle that can see the screen image. And the viewing angle is a reference value, [...]
As we all know, for LED displays, contrast ratio is one of the important parameters. The greater the contrast ratio, the clearer the image, and the more colorful it is. The contrast ratio of LED displays on the market varies greatly, and the value can easily differ by several digits. contrast ratio [...]
Grayscale, also known as color scale or grayscale, refers to the degree of light and dark changes in pixel luminescence. A base color grayscale generally has 8 levels to 1024 levels. For example, if the grayscale of each primary color is 256 levels, for dual color screens, the display color is 256x256 = 64K [...]
LED display brightness adjustment methods One is to change the current flowing through the LED, the general LED tube allows continuous working current in about 20 mA, in addition to the red LED saturation phenomenon, other LED brightness is basically proportional to the current flowing through; Another method is to use the visual inertia [...]
The aging of LED displays is an essential step in the production process of LED displays, as well as a detection link in the production and testing of LED displays, which is an important guarantee of the quality of LED electronic display products. The LED aging test is a very important link in product [...]
For the traditional LED display, the traditional LED display is bulky and expensive, which is not conducive to maintenance. The installation requires a lot of transportation and installation labor costs. The LED transparent display screen is highly transparent and thin. It can be used in exhibitions, airports, advertising media, chain stores, large shopping malls, [...]
