Samsung is a major manufacturer of Electronic Components such as lithium-ion batteries, semiconductors, image sensors, camera modules, and displays for clients such as Apple, Sony, HTC, and Nokia.smartphones, starting with the original Samsung SolsticeSamsung Galaxy line of devices.tablet computers, particularly its Android-powered Samsung Galaxy Tab collection, and is regarded for developing the phablet market with the Samsung Galaxy Note family of devices.Galaxy S22, and foldable phones including the Galaxy Z Fold 4. Samsung has been the world"s largest television manufacturer since 2006,memory chip manufacturerIntel, the decades-long champion.

The joint venture"s early products were electronic and electrical appliances including televisions, calculators, refrigerators, air conditioners, and washing machines. In 1970, Samsung established the joint venture Samsung-NEC with Japan"s NEC Corporation and Sumitomo Corporation to manufacture home appliances and audiovisual devices. Samsung-NEC later became Samsung SDI, the group"s display and battery business unit. In 1973, Samsung and Sanyo created Samsung-Sanyo Parts, the predecessor of Samsung Electro-Mechanics. By 1981, Samsung Electric had manufactured over 10 million black-and-white televisions.

In 2009 and 2010, the US and EU fined the company, along with eight other memory chip manufacturers, for its part in a price-fixing scheme that occurred between 1999 and 2002. Other companies fined included Infineon Technologies, Elpida Memory, and Micron Technology.immunity to Samsung Electronics for acting as an informant during the investigation (LG Display, AU Optronics, Chimei InnoLux, Chunghwa Picture Tubes, and HannStar Display were implicated as a result of the company"s intelligence).

In May 2015, Samsung announced a partnership with IKEA, in accordance with the Wireless Power Consortium, to co-develop furniture that would allow Qi inductive charging at the Mobile World Congress.LED products. The company"s SMART range of LED displays include Signage, Hospitality Display, TV, LED, Cloud Display, and Accessories. The company caters to the following industries: Retail, Corporate, Hospitality, and Transportation.

On 6 April 2017, Samsung Electronics reported that financials were up for the company in the quarter. The year prior, "memory chips and flexible displays accounted for about 68% of Samsung"s operating profit in the final quarter of 2016, a change from previous years when the smartphone business was the main contributor."

In May 2019, for the first time in Europe, 8K demonstration content was received via satellite without the need for a separate external receiver or decoder using a Samsung TV. At the 2019 SES Industry Days conference at Betzdorf, Luxembourg broadcast quality 8K content (with a resolution of 7680x4320 pixels at 50 frames/s) was encoded using a Spin Digital HEVC encoder (at a data rate of 70 Mbit/s), uplinked to a single 33 MHz transponder on SES" Astra 28.2°E satellites and the downlink received and displayed on a Samsung 82in Q950RB production model TV.

The digital-media business area covers computer devices such as laptop computers and laser printers; digital displays such as televisions and computer monitors; consumer entertainment devices such as DVD players, MP3 players, and digital camcorders; home appliances such as refrigerators, air conditioners, air purifiers, washing machines, microwave ovens, and vacuum cleaners.

Samsung Electronics produces LCD and LED panels, mobile phones, memory chips, NAND flash, solid-state drives, televisions, digital cinemas screen, and laptops and many more products. The company previously produced hard-drives and printers.

Samsung"s current AMOLED smartphones use its Super AMOLED trademark, with the Samsung Wave S8500 and Samsung i9000 Galaxy S being launched in June 2010. In January 2011, it announced its Super AMOLED Plus displaysSuper AMOLED displays – real stripe matrix (50 percent more sub pixels), thinner form factor, brighter image and an 18 percent reduction in energy consumption.

In October 2007, Samsung introducing a ten-millimeter thick, 40-inch LCD television panel, followed in October 2008 by the world"s first 7.9-mm panel.

In October 2013, Samsung disseminated a press release for its curved display technology with the Galaxy Round smartphone model. The press release described the product as the "world"s first commercialized full HD Super AMOLED flexible display". The manufacturer explains that users can check information such as time and battery life when the home screen is off, and can receive information from the screen by tilting the device.

The company started as a budget display monitor brand in the 1980s, producing cathode ray tube (CRT) monitors for computers, from which it then evolved. By the end of the decade, Samsung had become the world"s largest monitor manufacturer, selling over 8 million monitors by 1989.

During the 1990s to the 2000s, Samsung started producing LCD monitors using TFT technology to which it still emphasizes on the budget market against the competition while at the same time starting to also focus on catering to the middle and upper markets through partnership with brands such as NEC and Sony via a joint venture.S-LCD Corporation respectively from its former joint venture partners.

Samsung has introduced several models of digital cameras and camcorders including the WB550 camera, the ST550 dual-LCD-mounted camera, and the HMX-H106 (64GB SSD-mounted full HD camcorder). In 2014, the company took the second place in the mirrorless camera segment.

The company added a new digital imaging business division in 2010, and consists of eight divisions, including the existing display, IT solutions, consumer electronics, wireless, networking, semiconductor, and LCD divisions.

It merged consumer electronics and air conditioners in 2010 under the consumer electronics business division. The set-top boxes business was merged with the Visual Display Business division.

In December 2010, the European Commission fined six LCD panel producers, including Samsung, a total of €648 million for operating as a cartel. The company received a full reduction of the potential fine for being the first firm to assist EU anti-trust authorities.

In 2015, users on the website Reddit began reporting that some Samsung Smart TVs would display advertisements for Pepsi products during movies when viewed through the Plex application.Gigaom that they were investigating the matter.

2 Key Features: Fast spectrum analysis with 80 db dynamic range QAM/Digital TV analysis Integrated DOCSIS 3.0 cable modem Ultra-fast QAM signal lock Gated measurements Equalizer, frequency response and group delay FCC Analog/Digital Proof-of-Performance automated tests Transport stream (TS)/MPEG analysis in PID with TR MPEG monitoring Persistence testing In-Service error vector spectrum (EVS) testing Simultaneous display of QAM and spectrum analysis Integrated return path sweep Upstream signal generator Wifi Analysis IP Test 2

3 Error Vector Spectrum (EVS) Analysis The error vector spectrum analysis is new to handheld instruments. With EVS, the user can quickly detect and identify interference from the fast growing LTE network. This type of interference typically cannot be seen with frequency domain measurements as the interference signal is too weak. Gated Measurement The Gated measurement enables the engineer run in-service C/N,CSO, CTB measurements. Figure 4: Analog TV Gated Measurement Figure 1: EVS with interference Simultaneous display of Spectrum and QAM Analysis The DS2800 displays QAM signal spectrum analysis andqam measurement results on one screen. This new feature empowers the user to check the signal s different characters at the same time, and easily find the fault. Figure 2: EVS without interference Fast Spectrum Analysis Function The spectrum analyzer on the DS2800 has a frequency range of up to 2150 MHz, with a dynamic range of 80 db. Figure 5: Simulaneous Display of Spectrum and QAM Analysis Figure 3: Spectrum Analysis 3

4 Upstream Spectrum Persistence Technology The new spectrum persistence analysis enables in-service detection of transient noise and impairments hiding beneath the upstream signal. Traditionally, troubleshooting the upstream channels is done by finding a free upstream spectrum. However, with the introduction of DOCSIS 3.0, the upstream channel is now extremely crowded, making it difficult to distinguish the upstream signal from the interference signal. The new persistence analysis facilitates finding impairments such as CPD and impulse noise with a color coded spectrum display. DVB-C Signal Analysis DS2800 supports ITU-T J.83 Annex A/B/C standards. The test automatically provides power level, MER, BER, constellation measurements.

5 Equalizer, Frequency Response and Group Delay Analysis In a cable TV network, the most common signal impairments come from impendence mismatch and filters. Impendence mismatch can cause serious micro-reflection, which can overlay the transmission signal. This results in amplitude fluctuations or standing waves, which can affect signal quality. The equalizer, frequency response and group delay analysis are the best tools to troubleshoot these linear distortions. Figure 15: TR Monitoring Figure 12: Adaptive Equalizer Cable Modem Measurement The DS2800 includes a DOCSIS 3.0 cable modem which supports 4 bonded upstream channels and 8 downstream channels. It is also compatible with DOCSIS 1.x and 2.0. The measurement displays statistics such as downstream signal level, modulation type, bandwidth, symbol rate, MER, BER and upstream signal level, modulation type, bandwidth, symbol rate, UCD (Upstream Channel Descriptor), standard. User can change MAC address, choose DOCSIS mode, downstream channel and UCD. Basic network test tools include: Ping, Traceroute, PPPoE, FTP and Browser.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.
