  • The Function Of OLED (Organic Light Emitting Diode)

    Abstract- this paper presents OLEDs (Organic Light Emitting Diodes).How they work, what they are prepared of, and different policies to manufacture them with layers thicknesses, and the many functions for them. OLEDs function as both light source and color array at the same time; they are used to generate digital displays in devices. Due to their early stage of improvement, they normally release fewer lights per unit area than inorganic solid-state based LED point-light sources. Introduction-An OLED (organic light-emitting diode) is a sort of LED (light-emitting diode), where the emissive electroluminescent level is a film of organic compound which releases light in response to an electric current. This layer of organic semiconductor material…

  • Benzenethiol Ligand Study

    In this study, the effect of benzenethiol ligand on CdSe/ZnS core/shell quantum dots was investigated. Conventional long-chain oleic acid (OA) and trioctylphosphine (TOP) capping ligands were partially replaced by short benzenethiol ligands, and the improvement in the luminescence performance was observed in quantum dot light emitting diodes (QD-LED). Approximately 1.8 fold improvement was achieved for both the maximum luminance and maximum current efficiency for the QD-LEDs fabricated with…

  • Pulse Oximeter Essay

    The emitters and photo detector are placed so as to face each other through tissue about 5-10 mm in thickness. The diodes are switched turn on and turn off in rapid sequence so that each measurement set include an estimate of transmission of infrared light, red light and ambient illumination. The ratio of red to infrared light is determined and the corresponding oxyhemoglobin saturation is found from an empirically determined table. The individual measurements are made each second and fed into…

  • Describe The Relationship Between Speedometer And Tachometer

    speedometer, tachometer, and transmission temperature gauge. Due to the fact that it will be towing a heavy object and be putting stress on the motor, so it doesn’t get too hot the gauge is there to protect it. Now on a sport car your two main instruments will be the speedometer and the tachometer. The speedometer is there to show how fast you are going into relation when using the tachometer, it shows you how fast your engine is rotating and tells you when to shift the gears if it’s a manual…
