How much is the P2.5LED large screen in the hotel banquet hall stage? The LED display is mainly used to play videos, pictures, notifications, display text, etc. Our LED display can be displayed on the computer. The value behind the display specification model P is the distance between the two pixels or the lamp (unit is mm), so the point distances of P2.5, P3, and P4 are 2.5mm, 3mm, and 4mm, respectively. The number of points on the same area, P2.5 is more than P3, P3 is more than P4, for example, the number of P2.5 pixels on a 1 square meter area is 160,000 points, P3 pixels are about 111111 points, and P4 As long as 62,500 points, the smaller the distance and the higher the pixels, the better the picture clarity. Therefore, P2.5 and P3 display more clearly than P4. The smaller the point distance, the more difficult the production will be. The unit square pixels will increase, the cost will increase, and the price will be relatively improved, so P2.5 and P3 are more expensive than P4, but this is not to say that P4 is not good, because the screen The larger the point distance on the body is, the more suitable the viewing distance is. There is generally a formula for viewing distance = point distance / (0.30.8), which is an approximate scale. From this formula, the suitable viewing distance of Lianshuo P4LED display screen is 513m, and the effect will be very good when viewed within this scale, enough to meet the daily practice display effect. Of course, if you choose P2.5, P3LED display, the effect will be very good, but the cost will be higher.

How much is one square meter of P2.5LED large screen in the banquet hall of the hotel? Five methods for energy saving of LED display:
With the rapid development of society, energy saving has become a topic of increasing concern, and the LED industry is no exception. The investigation found that LED energy-saving products are widely welcomed by the public, such as LED energy-saving lamps, and LED display screens that also belong to the LED industry also have energy-saving functions, so how can LED display screens save energy? LED display manufacturers give you a detailed introduction to the five-step LED display energy saving method.
1. Selection of environmentally friendly materials
The LED display screen made of get more environmentally friendly materials, through a special processing technology, can achieve the purpose of waterproof, dustproof and ultraviolet radiation protection without pouring glue. It has fewer consumables than the products produced by the general process and is more environmentally friendly. Each customer has different criteria for selecting the display screen. It is important to select the right product according to the specific environment and field conditions used.
2. Design brightness adjustment device
In different weather conditions, the brightness of the occasion is different. In order to make the display effect of the LED display neither bright nor too dark, the LED display is specially designed with a brightness 256-level adjustment device and a function that automatically adjusts the brightness according to the surrounding environment. , It can ensure that the LED display can present a good display effect to the audience under various external brightness environments.
3. Constant current noise reduction technology
The LED display driver chip adopts the international LED display dedicated chip system, which is the leading manufacturer in the field of full-color LED display. Combined with the characteristics of its chip, the research has formed a constant current noise reduction technology to ensure that the influence of other noise source factors such as power supply on the LED electronic display screen is reduced to a lower degree. Some driver ICs can also save the original 5V voltage to 4.2V to achieve the energy saving function.
4. Strong convection heat removal system to stabilize the heat dissipation system
The LED display screen will release more heat after working for a long time. If the heat is not dissipated in time, it will cause a certain degree of damage to the screen body and affect the normal use of the screen. In order to ensure the normal operation of the display in a stable environment, it is necessary to strengthen the heat dissipation system of the LED display. After some researchers have studied the heat dissipation system of the display screen, a strong convection heat removal system has been developed, which uses the heat conduction effect of aluminum to make the heat dissipation system of the LED display screen more stable.
5. Power supply
The realization of the LED energy-saving display mainly starts from the power supply, and the half-bridge or full-bridge high-efficiency switching power supply is directly used on the existing LED display, and the synchronous rectification energy-saving effect is remarkable. Reduce the power supply voltage as much as possible in the state of constant current for the driver IC, and separate the power supply through the red, green, and blue dies to achieve better energy saving effects.
The LED display screen starts from five aspects: material selection, brightness adjustment, noise reduction processing, heat dissipation improvement and power supply, making the LED display screen make its own efforts for energy conservation and environmental protection from production to use.
Selection of supporting product materials for full-color LED display
Lamp and chip.
The LED lamp is not only an LED luminous tube, but also a key component of the LED electronic display screen, so it is necessary to adopt reliable quality and package mature LED products. The selected LED product must have good stability, small dispersion, HM greater than 4000V, small attenuation, strong pressure resistance, brightness, wavelength, high angle, good light distribution effect and resistance to temperature differences, humidity and ultraviolet rays.
2. Cabinet.
The whole adopts steel plate or aluminum material, and adopts an open door structure. The top of the box uses pins and the bottom uses a guide sleeve to ensure positioning between the boxes. The overall protection of the cabinet conforms to the IP65 standard. In addition, the structure must fully consider the heat dissipation problem.
3. Switch power supply.
The display is powered by a well-known certified switching power supply module. All switching power supplies have undergone rigorous testing, screening and aging. Ensure full compliance with international safety and quality certification requirements to meet the requirements of long-term stable and reliable operation of the display. Under rated operating conditions. Ensure the service life is greater than 10 years.
4. Connector.
