There are two different outdoor LED displays. Surface-mounted Display and Dual In-Line Package (DIP) diodes (SMD). Customers now frequently mistakenly think that we exclusively sell SMD and that SMD is superior to DIP, but it all depends on the device’s application. Additionally, we offer both outdoor DIP and Surface-mounted Display LED displays. Check out the OD10E P10 outdoor DIP LED display, the most used of our DIP LED displays. In any challenging outdoor situation, it offers stunning and enduring content. With the most advanced DIP technology, it can last for years. In addition, it is extremely energy efficient and helps save a lot of electricity. Now, let’s examine the distinctions between outdoor SMD LED displays and dip LED displays.
First off, what exactly is an LED?
A tiny electronic semiconductor called a light-emitting diode (LED) transforms electrical energy into visible light. An LED’s color, brightness, and power efficiency are all influenced by the chemical composition employed in its construction. LEDs don’t have filaments that can burn out or break as incandescent bulbs do.
We can divide LED displays according to the type of LED:
LED DIP display
SMD LED screen
LED COB display (future display technology, mini LED, micro LED)
Let’s discuss SMD and DIP outdoor LED displays. (Comparing indoor SMD with outdoor DIP needs to be revised.)
What is a DIP LED?
DIP (Direct In-line Package) (Direct In-line Package)
Three bubble-shaped color LED bulbs are used to construct this module, connected by two connectors. For mounting these DIP modules, through-hole soldering or sockets are used. With sockets, switching out the gadget is relatively easy, and there is also little chance of damage from overheating (which occurs during soldering). Each DIP outdoor module is weatherproofed using heat-dissipating silicone once assembled.
Describe SMD LED.
The three different colors of LED bulbs are combined into one thin casing and connected directly to a circuit in an SMD module. These diodes are tiny and can be positioned closer together because they are put on just one surface of the board. Surface-mounted Display modules are more frequently employed in indoor solutions because closer positioning yields a higher resolution. These modules can be produced in sizes as tiny as 0.6mm.
DIP and outdoor SMD DIP LED display advantages and disadvantages
Prons of DIP LED displays
Since the early 1960s, DIP outdoor LED displays have been in use, which is the original LED technology, it is the most developed and time-tested technology for outdoor LED displays. Because of its dependable and lasting qualities, it can withstand challenging environments.
The independent red, green, and blue LED lights that makeup DIP displays are connected by two connection feet. This layout will provide excellent heat dispatch.
DIP works well when there is a lot of direct sunshine, and the application doesn’t reflect outside light.
More energy-efficient than SMD.
Cons of DIP LED displays
DIP displays often have a greater thickness and weight since the bulbs are mounted separately.
The minimum pixel pitch is 10mm. A lack of room prevents lowering it.
DIP screens’ color uniformity is inferior to that of SMD screens since they are composed of separate red, green, and blue LED bulbs.
DIP LEDs suppliers provide high-end bulbs, raising prices above SMD screens.
Benefits of outdoor SMD LED displays
Since the LEDs can be placed closer together because they are directly on the board, the device is thinner and lighter and has a higher resolution.
SMD screens use three chips inside each LED to produce more vibrant colors and give better consistency.
Additionally, SMD LEDs frequently offer superior viewing angles. while DIP 140°/70° (or 120°/60°) is 140°v by 140°h.
Cons of outdoor SMD LED displays
Brightness is lower than DIP screens.
Power consumption increases along with heat dissipation.
With so many SMD LED light manufacturers on the market, there is a wide range in product quality, which significantly affects the price of outdoor SMD.
What distinguishes a side SMD transparent LED display from a front SMD transparent LED display?
A wide range of application scenarios for LED transparent screens can be found in many different industries, including automobile 4S stores, mobile phone stores, jewelry stores, brand clothing stores, sports brand stores, catering brand chain stores, brand convenience stores, as well as various exhibitions, stage beauty Performing Arts, etc.
Front SMD and side Surface-mounted Display are the two basic types into which transparent screens are currently subdivided.
Transparent SMD LED display on the front. It uses the most widely used product on the market, conventionally packed lamp beads.
Transparent LED display on the side. A few businesses have adopted side-emitting lamp beads designed especially for transparent screens. High permeability, several structural spans, and superb aesthetics define it.
These two types of transparent LED displays’ main advantages and disadvantages.
Initially, the transparent rate
The thickness of the PCB for the front SMD transparent screen must be more significant than the size of the lamp beads due to the diverse placements of the lamp beads, whereas the position and space of the side SMD lamp beads are less constrained. The side Surface-mounted Display transparent screen has a higher transparency rate than the front SMD one since the PCB filters light. The primary benefit of side-emitting transparent screens is this.
The transmittance comparison of two transparent screens with the same pixel pitch is depicted in the figure (for illustration purposes only).
2. The comparison of appearance:
The front SMD transparent screen’s driver IC can only be fitted on both sides of the light bar to avoid obstructing the light. This restriction is not present in the side Surface-mounted Display transparent screen, allowing the driver IC to be concealed behind the lamp beads. The front SMD screen strip driver IC can only control a certain number of lamp beads, which limits the length of the display strip. The front SMD transparent screen’s whole construction is lattice-shaped. The side SMD transparent screen’s single light bar can be extended.
3. The usage of driver IC is compared:
As a result of the front SMD transparent screen’s limited space for the driver IC, it is frequently necessary to set a more significant number of scanning lines, typically 16 scans and above. The number of scanning lines can be decreased, and the side Surface-mounted Display transparent screen driver IC is not initially constrained.
The display screen’s scan lines are few, it can operate with less electricity, and its refresh rate and grey level should be improved.
4. Evaluation of collision avoidance abilities
The impact resistance of the two screens varies due to the differing lamp bead installation positions. In the event of an external force, the front SMD lamp beads will be immediately affected, while the side SMD lamp beads won’t be directly affected.
5. Aspect ratio
Due to the location of the LEDs, which will be SMT on the underside or bottom of the LED strip, the PCB will obstruct some vertical view angles.
