If you've ever used a smartphone, tablet or touch screen computer, you've likely used a Thin Film Transistor touch screen. A TFT touch screen is a combination device that includes a TFT LCD display and a touch technology overlay on the screen.
An LED monitor (short for Light Emitting Diode) or LED display is a flat screen, flat panel computer monitor or television. The actual difference between this and a typical LCD monitor is the backlighting. The first LCD monitors used CCFL instead of LEDs to illuminate the screen.
Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide backlighting, whereas LED TV's used an array of smaller, more efficient light emitting diodes (LEDs) to illuminate the screen, which gave them a few advantages. Now, all LCD TVs use LED lights and are colloquially considered LED TVs.
Whenever you see or hear “LED screen”, it usually means an LCD panel with a backlighting provided by an array of LEDs (Light Emitting Diodes). LED backlit screens are more energy efficient and usually serve longer than CCFL. Most newer laptops and all brand-new laptops are made with LED backlit LCD panels.
An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. An OLED display can be driven with a passive-matrix (PMOLED) or active-matrix (AMOLED) control scheme.
A flat panel screen that uses the liquid crystal display (LCD) technology and connects to a computer. Laptops have used LCD screens almost exclusively, and the LCD monitor is the standard display screen for desktop computers. By 2004, LCD desktop monitors outsold the traditional, bulky tube monitors (see CRT).
The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting. Older monitors used a cathode ray tube (CRT).
Why is monitoring and evaluation important? At the programme level, the purpose of monitoring and evaluation is to track implementation and outputs systematically, and measure the effectiveness of programmes. It helps determine exactly when a programme is on track and when changes may be needed.
The LCD monitor, the most common kind of flat panel display. It is a newer technology than CRT. LCD monitors use much less desk space, are lightweight and use less electricity than CRT. They have been used for many years in the screens of laptop and notebook computers.
Monitoring is a systematic and long-term process that gathers information in regards to the progress made by an implemented project. First of all, Monitoring and Evaluation (M&E) are important for you to assess that your project is achieving set targets.
Improve program design and implementation. It is important to periodically assess and adapt your activities to ensure they are as effective as they can be. Evaluation can help you identify areas for improvement and ultimately help you realize your goals more efficiently.
As with most things in international development, there is no standard definition of a Monitoring and Evaluation (M&E) framework, or how it differs from an M&E plan. For many organisations, an M&E framework is a table that describes the indicators that are used to measure whether the program is a success.
In most cases an M&E system refers to all the indicators, tools and processes that you will use to measure if a program has been implemented according to the plan (monitoring) and is having the desired result (evaluation). An M&E system is often described in a document called an M&E plan.
Monitoring and Evaluation (M&E) is a process that helps improve performance and achieve results. Its goal is to improve current and future management of outputs, outcomes and impact.
There are several types of monitoring in M&E and they include process monitoring, technical monitoring, assumption monitoring, financial monitoring and impact monitoring.
- Process monitoring/ physical progress monitoring.
- Technical monitoring.
- Assumption monitoring.
- Financial Monitoring.
- Impact Monitoring.
Program process monitoring is an assessment of the process of a program or intervention. Process monitoring falls under the overall evaluation of a program. Program evaluation involves answering questions about a social program in a systematic way.
