(Active-Matrix Organic Light Emitting Diode).
Active-Matrix OLED Displays are named by the active drive construction for each pixel. The pixels individually have seperate logic control and power control. The pixel will be controlled off/on by the display controller IC, while the power is supplied directly to the pixels through the devices structure. Active-Matrix design is a more complex structure and higher-cost than Passive-Matrix designs, but unlike Passive-Matrix designs the designs can be scalable to larger sizes and higher resolutions without scaling the power profile nor impact to the OLED material degradation. These displays is suitble for stable industrial products that may seek similar look and feel to mobile phones, and high-end smart wearable devices. AMOLED displays have small format offerings for select wearables, but generally focus on sizes larger than most PMOLED offerings .
(Passive-Matrix Organic Light Emitting Diode).
Passive-Matrix OLED Displays are named by the passive drive construction for each pixel. The pixels illuminate with a row & column provide the necessary voltage differential and sufficient current to drive the pixel to illuminate. For a flat panel display with a resolution such as 128x64 pixels, this will require the display driver to multiplex both the logic and power both through the embedded display driver IC. The power will cycle and scan through all rows & columns with normal refresh frequency. This display is suitble for stable industrial products requiring small format displays under 3 inch diagonals. The resolution must be limited since power scales with size in a PMOLED drive system. This impacts the usable life of the PMOLED Display. For this reason, the focus of production is on smaller sizes and more modest resolutions. You will encouter these in various products like activity tracker wearables in the market. The displays are stable and offer industrial support.
(Resistive, Surface Capacitive, and Projected Capacitive).
Digital Pixel Displays is a manufacturer of resistive and capacitive touch interfaces. Sizes from 1" to 55" touch sensors for portable devices to large touch monitors and kiosks. We are vertically-integrated to manufacture surface and projective capacitive touch surfaces, mulit-wire resistive touch screens, and are focusing our R&D on next-generation solutions including non-contact gesture detection, haptic feedback touch, and industry-specific innovations for industrial touch screen usage.
(Thin Film Transistor Liquid Crystal Displays).
TFT-LCD Displays are a cagegory of liquid crystal displays (LCDs) characterized by a Thin Film Transistor Layer deposited on the substrate for an active-matrix control design. Traditional passive LCDs require the display primary controller to drive all individual pixels both with logical power for on/off state, but also for power drive. The active-matrix element of the TFT-LCD separates the power from the logical components allowing the primary display controller to drive the logical state, while the transistors pull power directly seperately retaining power at all pixels simultaneously. Active Matrix designs allow for higher contrast ratios with the direct power drive and ensure scalability to larger display sizes and resolutions such as monitors and televisions. TFT-LCD displays are suitable for most applications and are highly proven in the field in almost every industry.
