You must have heard of P1.5 LED display when you come into contact with content related to LED display, what exactly is P1.5 LED display? If you are curious about this, then read these related contents together with JYLED.
What is P1.5 LED screen
P1.5 LED screen refers to the LED screen spliced by the pixel pitch of 1.5mm LED module, for the LED screen, a core specification is the pixel pitch, the pixel pitch to a certain extent determines the resolution and viewing distance of the LED screen.
P1.5 LED screen components
P1.5 LED module
A complete P1.5 LED module contains LED beads, PCB boards, mask kits and driver ICs.
The LED beads are the basic pixels of the display imaging, the PCB board exists as a substrate for fixing the LED beads, the driver ICs are responsible for dealing with the timing and brightness of the LEDs, and the mask kits can prevent the external dust and moisture from entering the LED screen. External dust and water vapor into the LED module to destroy the electronic components.
Video Controller
The LED video controller can convert the external video content source signal into a signal that can be read by the P1.5 LED screen, and it can also control the way of displaying the screen of the P1.5 LED screen, adjusting the display color, contrast and some other basic parameters of the display, so as to optimize the display screen.
LED Cabinet
LED screen cabinet is the bracket of P1.5 LED module, which is formed by several LED modules fixed on the cabinet, and then several cabinets are spliced together to form a complete P1.5 LED screen.
Power supply
The power supply we usually use is usually AC, and now the LED screen mainly uses DC, so there is a need to have a switching power supply for the LED screen to convert the AC power to DC power, so that the P1.5 LED screen can work normally and stably.
Characteristics of P1.5 LED screen
High resolution
The same size LED display, the smaller the pixel pitch, the higher the resolution.
Generally in the LED display industry, 2mm below the LED display, we call it fine pitch LED display, therefore, P1.5 LED screen belongs to the small pitch display, it is extremely high resolution, the screen image is clear, rich in detail, and even if the screen is viewed from a close distance, the screen will not be pixelated.
Rich color
P1.5 LED screen adopts driver IC with high quality and good performance, so it is able to control the LED lamp beads with a wide range of brightness, the red, green and blue primary colors of LED lamp beads according to the different brightness of the color combination with the color, which can produce thousands of colors.
The driver IC of P1.5 LED screen can control more brightness levels, it can produce more kinds of colors, theoretically P1.5 LED screen can display 281 trillion kinds of colors.
High brightness
In general, P1.5 LED screen this small pitch LED screen is not used for outdoor use, its pixel pitch determines its viewing distance can not reach the outdoor super long distance viewing requirements.
Most P1.5 LED screens are used indoors, and the brightness can reach 600~800 nits, while meeting the basic display requirements indoors only requires a brightness of 500 nits is enough, therefore, the high brightness of P1.5 LED screens can fully meet the indoor viewing requirements.
High Contrast Ratio
Deeper black enhances the contrast of colors. The higher contrast ratio of P1.5 LED screen results in stronger color visibility and higher quality of the displayed picture.
Seamless Splicing
P1.5 LED modules are extremely narrow, and the seam is not visible to the naked eye when two modules are spliced together, nor does it affect the overall effect of subsequent screen viewing.
Large Viewing Angle
Whether horizontally or vertically, viewers are able to see the content of the P1.5 LED screen from a viewing angle of over 160 degrees.
Efficient Heat Dissipation
Although the thermal energy conversion of LED display is low, a small amount of heat will still be generated in the process of energy conversion. The back cover of the cabinet of P1.5 LED screen will be designed with heat dissipation holes to guide the natural ventilation to dissipate heat.
Keep P1.5 LED screen non-high-temperature operation can maintain the stability of equipment operation and extend the service life of the equipment.
Several types of P1.5 LED screen
SMD P1.5 LED screen
SMD P1.5 LED screen refers to the use of SMD (Surface Mount) technology to manufacture P1.5 LED modules spliced together to form the screen, SMD LED technology is the more common LED technology on the market, it’s process method is mature, the cost is low, and therefore is very popular with users.
COB P1.5 LED Screen
COB P1.5 LED screen is a display screen made up of P1.5 LED modules manufactured using COB technology. COB LED technology means that the LED chips are mounted directly on the substrate to form a huge uniform LED chip.
The advantage of COB LED technology is that this enables a higher density of LEDs to be installed, and it is able to perform excellently in the field of tiny pitch LED screens.
HOB P1.5 LED screen
HOB P1.5 LED screen refers to the screen composed of P1.5 LED modules produced by using HOB LED technology. HOB LED technology increases the stability of the LED beads by filling new optical thermal conductive materials between the LED beads on the PCB substrate, and also effectively protects against water and dust.
Comparison between P1.5 LED screen and P2 LED screen
Pixel Pitch
The pixel pitch of P2 LED display is 2mm, and the pixel pitch of P1.5 LED display is 1.5mm, the pixel pitch of P1.5 LED display is smaller, and the resolution of P1.5 under the same size is higher and the picture quality is better.
Encapsulation type
The encapsulation technology of P2 LED display is basically SMD technology, and the encapsulation technology of P1.5 LED display is mostly SMD technology and COB technology, of which COB technology is more expensive, and at the same time, the stability of LED display is better.
Price
The LED bead density of P2 LED display is lower than that of P1.5 LED display, so the cost is lower and the price is cheaper.
Application of P1.5 LED screen
Shopping malls
The display screen for playing advertisement in shopping malls need high definition and bright color, P1.5 LED display has high resolution and high quality driver IC, it can meet this point perfectly, the small pitch of P1.5 LED display can also allow the audience to watch it in close proximity, which is in line with the demand of shopping mall venues.
Stage backdrop screen
P1.5 LED display has excellent driver IC performance, high performance driver IC can drive a higher refresh rate, high refresh rate makes P1.5 LED display as a stage backdrop display screen, can carry the camera shooting, LED screen will not produce water ripples.
Conference Room
The viewing distance of conference room is usually within 5m, and the best viewing distance of P1.5 LED display is 1.5m~5m, using P1.5 LED display in conference room can ensure that almost everyone is within the best viewing distance.
How to buy P1.5 LED screen correctly
Determine the core demand
Firstly, determine your demand, clarify the use of P1.5 LED display you buy and the installation environment, only then can you calculate the size of P1.5 LED display and choose a P1.5 LED display with appropriate brightness according to the ambient light, all these can be found in JYLED to help you calculate.
Calculate the cost-effective formula
In general, we calculate the cost formula: total cost = (purchase cost + maintenance cost × 5 years)/LED screen area
After calculating the total cost, you can estimate according to your own ideas, whether it meets the expectation or not, if it does not, then you need to contact JYLED to help you adjust the cost.
Real Project Verification
When you can not make a decision, you can find JYLED to send you the actual project we have done on-site testing, through the video to watch the installation of P1.5 LED display screen whether it meets your expectations.
Conclusion
P1.5 LED display in the small pitch LED display, very cost-effective, not only do not have to bear the high price of micro LED display, but also than other larger pixel pitch LED display screen picture quality is higher and clearer, in recent years, P1.5 LED display is definitely a choice will not disappoint you.
