Taxi Top advertising LED display from Ocolour VS other taxi Top LED screen


Ocolour led:


Outdoor SMD2525 led lamp:

1.brand led chips and led lamp encapsulation supplier to ensure the quality & size of chips and lamps

2.special silicone packaged in the led lamp cup to protect the damage of UV in the sunlight. so to extend the lifespan of led

3.large-sized led chips with small electric current to save energy consumption and prolong the lifespan of led; Generally. brightness of P5 and 1/8 scan will be about 6500-6800nits;


Other led:


Indoor SMD3528 led lamp

1.indoor led chips and lamps. SMD3528 is common and nobody. and the led chips are not stable in size and supplier. so the quality is out of control;;

2.Indoor SMD3528 has no Anti-UV function. it is easy to cause failure of the led lamps. and reduce the lifetime of the led

3.brightness of indoor SMD3528 is very low. In order to get higher brightness. the only way is to improve the electric current. As a result. the power consumption improves. Generally. brightness of P5 and 1/8 scan will be about 1800-2500nits;

Cover material

Frosted anti-UV PC is applied:

1.PC are easily worked.molded, and thermoformed;

2.Frosted PC can anti glaring & dazzle light;

3.anti-UV better

Acrylic

1.easy to be scratched as its hardness is low; can not anti high temperature; will become yellow after being rained;

2.transparent acrylic is has glaring and dazzle light are common;

3.no anti-UV function and fragile;

Cabinet material

Aluminum body + stainless steel installation base

1.light-&-thin aluminum body & anti-vibration;

2.stainless steel base has better extensional viscosity;

3.no rust;

4.IP65 certificate to reduce vibration and fit all types of roads;

Iron body and installation base

1.Iron is heavy;

2.extensional viscosity of iron is general;

3.easy to be rusted and corroded

4.structure is poor and week and the shape is easy to be changed by vibration;


Driving IC

1.brand Taiwan MBI5124 driving IC bring better displaying presentation

2.DB4973 mosfet to get better lining

3.NXP brand dataway driving IC has better stability;

1.Less known and inferior brand IC driver can only get common display presentation;

2.general line driving IC. no blanking internals

3.Less known and inferior brand dataway driving IC is applied. There is failure possibility;

Internal wiring

1. Hard connection is applied to fix the screws and prevent loosening;

2. All connectors are copper-plated with gold. High reliability is obtained;

3. Cable with color line. So it has better Weatherability; With lock design to ensure reliability


1. Use ordinary cable connection. Not suitable for vehicle application;

2. The connector is made of steel-covered by copper, so there is potential failure possibility in the long application period;

3. Use conventional cable. Poor weather resistance. No belt lock design, so the reliability is poor;


Module design

1.PCB is independently designed for vehicle-mounted screen. All of factors are take into Consideration. So it has highest security.

2. Larger-sized PCB W320 XH320mm design. Good flatness & better Connection, and less connectors are used. Easy maintenance;

3. No bottom shell design. Light weight;

4. Easy to disassemble and maintenance;

5.PCB produced by professional manufacturers. Thick copper thickness. Over-current uniform. Long time without any hidden danger


1. Application of public board; failure possibility is high;

2. Small PCB design. Flatness is not good to control. Connectors are used more. Failure rate increases. Maintenance is not convenient;

3. Common mold so the use of bottom is a must. Weight increase

4. back-disassembled design, so the maintenance is not convenient;

5.PCB produced by the public manufacturers. Copper foil thickness is thin. The current is not uniform. Easy to cause color.


External wiring

1. All use of aerial head design. Waterproof. Anti-shock & anti-off;

2. Easy to disassemble


1. Use conventional screw connection. Not suitable for application on the vehicles;

2. inconvenient disassembly


Thermal design

1. Bottom shutters design, you do not have to worry about waterproof problems

2. Temperature sensing switch controls fan convection;

3. High brightness. Small electric current design to reduce heat;


1. Side louver. Easy water

2. No fan.

3. Low brightness. High current & high heat;



Brightness sensor design

1. Use the top of the shell window plus transparent PC cover to show the sensor. Sensor in the internal. Not easy to crash. Better sensitivity;

1. No installation position;

2. Fixed on the side;

3. Fixed at the bottom and signal is poor;


Alarm function1. There is one key alarm display function1. no
Wireless control design (this option is optional.)

1. Reduce the alignment. The entire screen has only two DC power lines;

2. Through the remote control. You can control the ON/OFF;

3. Through the remote control Can control the screen body switch on/off;

3. Through the remote control. Can

be one key alarm;


1. no
Outlook design

1. Patent streamlined design. Wind resistance is small and appearance smooth;

2. Patented arced PCB and module design;

3. Large “empty car” & “guest occupied” design. Easy to identify;

1. Conventional design. Wind resistance is huge and appearance is not smooth;

2. Conventional module. Can not make rounded corners;

3. It is not easy to identify;


Spraying material

2. Available wireless control power on and off;

3. Can be set screen-off but power does not turn off. Power saving and save the start time. No exhausted battery power danger;

4.4.2V low-voltage output. Reduce the power consumption of the whole machine to increase part of the life of the whole circuit;

5. Short-circuit protection; Self-recovery function;

6. With the car start and flameout. Delayed start and shutdown design. Suitable for vehicle installation and use. To protect the vehicle battery and engine life.

7. High conversion efficiency design. Small heat. Low overall power consumption;

1. With conventional power supply, it is difficult to control the power supply

2. No wireless control design options

3. There is no function of turning off the screen, which is easy to cause the battery to run out of power

4. Using 5V output power. High power consumption!

5. No short circuit self-recovery function

6. Do not have the delay switch machine. Due to frequent high current impact lead to loss. Damage to the battery; power efficiency is low. Leading product power consumption.

7. Low conversion efficiency, high overall power consumption;
