PMOLED
Affordable Brilliance for
Everyday Displays
PMOLED (Passive Matrix Organic Light-Emitting Diode) is a type of display based on organic light-emitting diode technology. It is a variant of OLED that uses a passive matrix drive method to control pixels. Each pixel is controlled by the current at the intersection of rows and columns. Compared with AMOLED (Active Matrix OLED), the driving circuit structure of PMOLED is relatively simple and does not require a large number of thin-film transistors. This makes PMOLED low-cost to manufacture and suitable for small-size and low-resolution display applications, such as mobile phone screens, watches, MP3 players, etc.
Structure
The structure of PMOLED includes cathode, organic layer and anode. The anode and cathode are perpendicular to each other, and pixels are formed at the intersection of the cathode and anode, which is the part that emits light. The external circuit applies current to the selected cathode and anode to light up the pixels in the array in a scanning manner to form an image.
Features
PMOLED (Passive Matrix Organic Light-Emitting Diode) has the following characteristics
Simple Structure
The driving circuit structure of PMOLED is relatively simple and does not require a large number of thin-film transistors. Each pixel is controlled by the current at the intersection of rows and columns, so the manufacturing cost is low.
Low Cost
Due to the simplified driving circuit and manufacturing process, PMOLED has a low cost and is suitable for small-size and low-resolution display applications.
Low Power Consumption
In static display mode, PMOLED is able to achieve low power consumption because pixels only consume energy when they change. This makes it suitable for scenes that need to display static content for a long time, such as digital clocks or small information displays.
High Contrast
PMOLED is able to achieve a high contrast because it is a self-luminous technology, and each pixel can emit light independently. This makes the image have a clearer and more vivid effect when displayed.
Fast Response
PMOLED has a fast response speed, which can achieve a high refresh rate and smooth dynamic display effect, and is suitable for watching high-speed content such as videos and games.
Small Size Application
Due to low cost, simple structure and low power consumption, PMOLED is often used for small-size information displays, such as mobile phone screens, watches, MP3 players, etc.
Limited Application Scope
Due to the limitation of passive matrix drive, PMOLED is limited in application to large size and high resolution display. Therefore, it is mainly used for small information display and not suitable for high resolution application scenarios such as large TV screens.

Application Areas
PMOLED is suitable for small-size information displays and portable electronic devices. It has been widely used due to its low cost, simple structure, high contrast and fast response.
Small-size Information Display
PMOLED is often used in small information displays, such as smart watches, sports bracelets, health monitoring equipment, etc. Due to its low cost, simple structure and low power consumption, it is suitable for the display needs of small-size devices.
Portable Electronic Devices
PMOLED is often used in displays of portable electronic devices such as MP3 players, portable game consoles, handheld GPS, etc. due to its high contrast, fast response and low power consumption.
Automobile Dashboards and Control Panels
PMOLED is also widely used in automobile dashboards and control panels to display vehicle speed, fuel consumption, navigation information, etc. Due to its high contrast and fast response, it can provide clear display under various lighting conditions.
Industrial and Medical Equipment
PMOLED is also used as an information display in industrial control and medical equipment to display monitoring data, operation interface, etc. Its fast response and high contrast make operation more convenient and efficient.
Consumer Electronics
In addition to the above fields, PMOLED is also used in some consumer electronics products, such as mini TVs, portable video players, digital cameras, etc. Its high-quality image display effect can enhance the user experience.
The Difference Between
PMOLED and AMOLED
There are some obvious differences between PMOLED and AMOLED in terms of driving mode, structure and application. It is important to choose suitable OLED technology according to different needs and application scenarios.
Working Principle
PMOLED
Passive Matrix OLED uses a passive matrix approach to drive OLED pixels. In PMOLED, each pixel is controlled by a conductive material at the intersection of rows and columns. When a voltage is applied between rows and columns, the pixel at the intersection emits light.
AMOLED
Active Matrix OLED uses an active matrix approach to drive OLED pixels. In AMOLED, each pixel is controlled by a thin film transistor (TFT) and can be turned on or off independently. This allows AMOLED to more precisely control the brightness and color of each pixel.
Structure
PMOLED
PMOLED has a relatively simple structure, usually consisting of a glass substrate, an organic light-emitting layer, a metal anode, and an ITO cathode.
AMOLED
AMOLED has a relatively complex structure, usually including a glass or plastic substrate, a transparent conductive layer, a thin film transistor (TFT), an organic light-emitting layer, and an encapsulation layer.
Drive Mode
PMOLED
PMOLED is relatively simple to drive and usually uses a lower voltage, but due to its passively driven characteristics, it has a low refresh rate and is not suitable for high-speed display scenarios.
AMOLED
AMOLED uses an active drive method, so it can achieve a higher refresh rate and faster response speed, which is suitable for high-speed display scenarios such as video playback and gaming.
Cost and Manufacturing
Complexity
PMOLED
Due to its simpler structure and driving method, the manufacturing cost of PMOLED is relatively low.
AMOLED
Due to its complex structure and active matrix driving method, the manufacturing cost of AMOLED is high.
Application
PMOLED
Usually used for small-sized displays, such as small smart devices, watches, MP3 players, etc.
AMOLED
Due to its high refresh rate, response speed, and high image quality, AMOLED is usually used for medium and large-sized displays, such as smartphones, tablets, TVs, etc.
