Considering the typified value obtained from the manufacturer’s specifications, four technologies—Liquid Crystal Displays, electronic paper, Organic Light-Emitting Display and Electroluminescent Displays—were selected in a first iteration. For each of them, several features, including size and brightness, were assessed in order to ascertain possible proportional relationships with the rate of consumption. To normalize the comparison between different display types, relative units such as the surface power density and the display frontal intensity efficiency were proposed.

Einstein at Home 62 3 HOD Message Today we find that information technology has become overwhelmingly pervasive, while its parent, computing science, has become correspondingly hard to find. While many CS educational institutions have shifted focus from core CS. This is the single most important attribute of the education offered here. Our department has remained true to the vision on which it was founded. There are several ways to present the canonical core of computer science. Over the years we have developed a distinct style and method that bridges the theory - practice divide while remaining grounded in the core. Technology changes rapidly, especially in the field of computing, whereas the science, if it changes at all, does so much more gradually. Our understanding is that persons who are clear and thorough about the fundamentals can adapt to rapid changes in technology relatively easily.

Bahan Ajar Komputer Dasar dan Pemrograman Page 1 A. Pengertian Komputer Komputer adalah alat yang dipakai untuk mengolah data menurut perintah yang telah dirumuskan. Kata komputer semula dipergunakan untuk menggambarkan orang yang perkerjaannya melakukan perhitungan aritmatika, dengan atau tanpa alat bantu, tetapi arti kata ini kemudian dipindahkan kepada mesin itu sendiri. Asal mulanya, pengolahan informasi hampir eksklusif berhubungan dengan masalah aritmatika, tetapi komputer modern dipakai untuk banyak tugas yang tidak berhubungan dengan matematika. Secara luas, Komputer dapat didefinisikan sebagai suatu peralatan elektronik yang terdiri dari beberapa komponen, yang dapat bekerja sama antara komponen satu dengan yang lain untuk menghasilkan suatu informasi berdasarkan program dan data yang ada. Adapun komponen komputer adalah meliputi : Layar Monitor, CPU, Keyboard, Mouse dan Printer (sbg pelengkap). Tanpa printer komputer tetap dapat melakukan tugasnya sebagai pengolah data, namun sebatas terlihat dilayar monitor belum dalam bentuk print out (kertas). Dalam definisi seperti itu terdapat alat seperti slide rule, jenis kalkulator mekanik mulai dari abakus dan seterusnya, sampai semua komputer elektronik yang kontemporer. Istilah lebih baik yang cocok untuk arti luas seperti "komputer" adalah "yang memproses informasi" atau "sistem pengolah informasi." Saat ini, komputer sudah semakin canggih.

  • State of the Art and New Developments in Optoelectronic Displays
    State of the art and new developments in optoelectronic displays A. SCHAUER Starting by classifying optoelectronic displays in three categories - commercially established, engineering models and under research and development; the present state of the art is reviewed and significant new developments are noted. In comparing the features of the various types of display, their information handling capabilities are discussed in detail and future perspectives for displays with high information handling potentials are pointed to. Optoelectronic displays represent a highly dynamic branch of industry in which established techniques are being further refined while at the same time new principles are undergoing explorative study. The incentive for this line of work stems from the need for the growing torrent of ~1 Contrllelectrode~ information to be visually displayed by suitable devices. This is accomplished with the aid of displays which form an interface between the human operator and the machine. Displays can be classified according to various aspects. One simple but extremely important consideration for the user, i l /Cathode is availability, on the basis of which displays will be classified in three categories: • commercially established • engineering models • under research and development (Table 1).

  • Glossary Document
    - Glossary Document - Active Area: The area of the display or touch panel that is useful for touch or viewing. Active Matrix = AMLCD (See also TFT) Active matrix liquid crystal display (LCD). A Liquid crystal based display technology that uses a switch at each pixel to create high resolution and fast response times. One type of LCD is known as thin film transistor (TFT) LCD, in which the switch used is a thin film transistor. Displays based on this technology range from as small as 1" diagonal up to 100" diagonal. Active Plate Another term for the glass substrate that contains the array or thin film transistors (TFTs) in an active matrix liquid crystal display (LCD). This is also known as an array or backplane. Amorphous silicon (a-Si) A semiconductor film used as the active layer in most active matrix liquid crystal displays (LCDs). It is based upon the electronic properties of a glass alloy of silicon and hydrogen. Analog to Digital Controller: A controller which converts an analog signal to a digital signal thus providing the input to the display in a digital format. Analog Resistive Touch Panel: This touch panel is comprised of two transparent resistive layers, separated by small spacers. Touching the screen causes the two layers to come in contact and form a switch closure. By measuring the voltage gradient in the horizontal and vertical axis, position can be determined. Analog RGB: Separate Red, green, and blue video signals used in conjunction with composite sync or separate horizontal and vertical sync. Analog Signal: A signal that travels continuously.

Email: [email protected], [email protected], [email protected], [email protected], [email protected] Article Received: 09 November 2019 Article Accepted: 17 January 2020 Article Published: 05 February 2020 ABSTRACT This technology is increasingly being used in a number of applications which benefit from their light weight, favourable dielectric properties, robust, high circuit density and conformable nature. Flexible circuits can be rolled away when not required. To replace glass, plastic substrate must offer properties like clarity, dimensional stability, low coefficient of thermal expansion, elasticity etc. Using the leading cholesteric liquid crystal technology of ITRI, we develop a rewritable, environmentally friendly thermal printable e-paper. The e-paper, devised to reduce traditional paper consumption, achieves a high resolution of 300 dpi with a memory function. In addition, we report on the ITRI's initial success in demonstrating a complete R2R process for multisensing touch panels on thick glass substrates provided by Corning. Recent advances in organic and inorganic based electronics proceeds on flexible substrate, offer substantial rewards in terms of being able to develop displays that are thinner, lighter and can be rolled when not in use. This paper will discuss about the properties, preparation methods, applications and challenges in this rapidly growing industry.
