“…The EML layers of sub-pixels of three colors were deposited one after another using another shadow mask (Mask2) that has 128 by 160 slits. The EML layers were formed by using the mask sliding method [8] . On the course of depositing the three color EML layers, it needs to slide the Mask2 two times and slide 80µm in cathode direction one time.…”

A full color 2.2″ passive matrix organic light-emitting diodes (OLEDs) with 128 (RGB) * 160 pixels was developed. The display features that driving circuit can transform 18 bits gray-scale data from a PC to the OLED panel via a DVI channel. The size of the pixel was 240μm 240μm, while that of mono sub-pixel is 190μm 45μm. The lifetime of panel was estimated over 5000h because of the use of dual-scan driving technology, and the power consumption of the display was 300mw about when the average luminance of panel reach 40cd/m2.

“…Patterning of light emitters can be achieved using a matched shadow mask for separately locating the red, green and blue emitters [35]. Figure 4 illustrates a sliding mask for RGB emitters [36]. The mask patterning method is more effective than other techniques, as RGB cell structures are the most suitable for colour purity and luminance effi ciency using optical interference.…”

Light‐emitting devices have potential applications in functional and ‘intelligent’ textiles and clothing. Much research work has been conducted on electroluminescent devices based on small organic molecules and polymers due to their potential application in new generation displays. An overview is presented of progress in the development of organic and polymer light‐emitting devices. The fabrication processes, materials and methods of improving their performance are reviewed. Attention is given to the potential application of flexible displays and the patterning method for producing a full colour display. Analytical methods are also discussed.

“…[4] Use of anti-reflection coatings is widely prevalent. [5] However, in the present design, it is not expected to result in a dramatic change in daylight contrast values since only a small fraction of the ambient light is reflected at the substrate. More commonly, the LED is provided with a circular polarizer (quarterwave retarder and a linear polarizer) (shown in Fig.…”

For most applications of displays based on organic light‐emitting diodes (LEDs), it is desirable to have good daylight contrast in combination with a high intensity of emitted light. The conventional approaches to enhance the daylight contrast, using a black cathode or circular polarizers, result in a significant loss of light emitted by the LED. A rather novel approach to enhance daylight contrast while keeping loss of emitted light to a minimum is the introduction of a chiral‐nematic film in the device. This approach leads to an increase in light efficiency by a factor of 1.8 (with respect to circular polarizers) with some loss in daylight contrast values within the reflection band of the chiral‐nematic film. Outside the reflection band, however, the contrast approaches infinity.
