However‚ due decreasing component cost (especially production of electronic diode and cathode ray – important components for TVs at that time) from ASEAN Countries‚ they decided to create new plants in ASEAN – as a result‚ more schools in ASEAN are starting to open basic electronic education (unique opportunity for

It may be frustrating when a tired person gets into bed and remembers he had forgotten to switch the bed light off. The project ‘automatic night lamp with morning alarm’ helps avoid this problem by switching on an LED itself when it detects darkness in the room. The LED serves as a bed lamp or a reading lamp

commercially available SiC Schottky diodes with different voltage and current ratings‚ VJFET‚ and MOSFET samples have been tested to characterize their performance at different temperatures ranging from −50°C to 175°C. Their forward characteristics and switching characteristics in this temperature range are presented. The characteristics of the SiC Schottky diodes are compared with those of a Si pn diode with comparable ratings Keywords: SiC; MOSFET; JFET; Schottky diode. Introduction With

The OLED is a solid-state devices composed of thin films of organic molecules that create light with the application of electricity. To compare with LCD system‚ OLED is Thinner‚ Faster‚ More efficient‚ Wider‚ and more Flexible. actually‚ it will be a next generation display and the future’s light source. So to get close with new technology‚ we started on research that. Main purpose is using organic materials to produce the Red‚ Green‚ and Blue OLED‚ and to improve the efficiency. For that we have
