海豹陪我去聽平面顯示器概論
This course introduces the flat panel displays (FPDs) by covering the fundamental physics of such a wide spectrum of display technologies, including display materials, process, design and operating mechanisms et. al. Basic operation principles and underlying physics for thin-film transistors (TFTs) LCDs, PDPs, LEDs, OLEDs and FEDs are also included.
The LCD is a non-emissive display. From the electrical viewpoint, each pixel is a light switch driven by a TFT. To reduce leakage current of the capacitor, the liquid crystal material should have a high resistivity. Moreover, to achieve a high contrast ratio, a wide viewing, most direct-view TFT-LCDs require a switchable liquid crystal layer and two absorption-type sheet polarizers with compensation films
In contrast, the emissive displays, are introduced. PDP can be considered as consisting of millions of miniature fluorescent lamps on a single panel. LEDs and OLEDs are the electroluminescent devices with crystallized semiconductors and amorphous organic materials, respectively. A FED is a type of flat cathode ray tube, which has all the advantages of this mature technology.
