TUBITAK UME Photonics and Electronic Sensors Laboratory produced the first OLED screen prototype in Turkey.
Photonics and Electronic Sensors Laboratory of UME Chemistry Group Laboratories has successfully produced 42-pixel PMOLED prototype modules. These modules were produced in 4 different colors: yellow, red, blue and green. The next step of this work is to develop displays that can be used in microdisplay applications such as high-definition televisions and cell phones and transfer them to industry. Thus, it is aimed to bring the next generation OLED display technology to Turkey.
OLEDs have started to be used in next generation display technology as an alternative to the LCD displays used today. They can also be used as a planar light source for panel illumination. While OLEDs provide uniform diffuse light panels, they can also be made transparent and flexible.
OLEDs and LCD display technologies offer many advantages when compared:
- The OLED screen structure does not require backlighting,
- OLED displays require lower power consumption,
- OLED displays are easier and cheaper to manufacture,
- OLED response time is 100 times shorter,
- OLED displays have a very high contrast ratio,
- OLED display image quality is better than LCD at wide angles,
- OLED displays can be thinner and lighter and, more importantly, can be applied to transparent and flexible substrates.
OLED displays are divided into two classes according to their driving methods: passive matrix OLED (PMOLED) and active matrix OLED (AMOLED). In PMOLEDs, the cathodes and anodes are formed by thin strips that cut each other perpendicularly and the organic layer between them is coated as a whole surface. The intersection of the anodes and cathodes forms the pixels.
