H:PMOLED Characteristics


1.Display Structure: PMOLED displays consist of an array of organic light-emitting diodes (OLEDs) arranged in rows and columns. Each OLED acts as a single pixel and emits light independently.


2.Passive Matrix: PMOLEDs use a passive matrix addressing scheme, where each row and column intersection in the display matrix is controlled by a driving circuit. This circuit applies voltage to the selected pixels to activate them.


3. High Contrast and Color Saturation:PMOLED displays offer high contrast ratios and vibrant colors. Since each pixel emits its own light, PMOLEDs can achieve deep blacks and vibrant colors without the need for a backlight.


4. Power Efficiency: PMOLED displays are generally power-efficient. They consume power only for the pixels that are active, as OLED emit light when a voltage is applied to them. In contrast, LCD displays require a backlight that consumes constant power regardless of the content being displayed.


5.Thin and Flexible: PMOLED displays are relatively thin and can be manufactured on flexible substrates. This makes them suitable for applications where flexibility or bendability is desired, such as curved displays or wearable devices.


6. Limited Resolution and Size: PMOLED technology has certain limitations compared to other display technologies. PMOLED displays are typically limited in resolution, and their pixel densities are lower compared to active matrix OLED (AMOLED) or LCD displays. Additionally, PMOLED displays are more suitable for smaller-sized screens due to manufacturing constraints.


7.Screen Persistence: PMOLED displays are susceptible to a phenomenon called screen persistence or burn-in, where prolonged display of static images can result in image retention or permanent damage to the display. However, etc
