sentences: The Apple Thunderbolt Display is a 27-inch flat panel computer monitor that was sold by Apple Inc., introduced on July 20, 2011 and discontinued on June 23, 2016.
 It was the final standalone display designed and sold by Apple.
 It replaced the former Apple LED Cinema Display.
 New to the Thunderbolt Display was the switch from Mini DisplayPort and USB to a single Thunderbolt connection for data transfer between computer and display.
 The increased throughput from switching to Thunderbolt enabled inclusion of a Gigabit Ethernet port and a FireWire 800 port on the display.
 Older model Macs introduced prior to 2011 with Mini DisplayPort are incompatible with the Thunderbolt Display.
The PMI-80 was a single-board microcomputer produced by Tesla Piešťany, Czechoslovakia, since 1982.
 It was based on the MHB 8080A CPU (a Tesla clone of the Intel 8080), clocked at 1.111 MHz.
 Instead of a raster graphic display output and classical keyboard, it had a calculator-style nine-digit seven-segment red LED display and a 25-key calculator-type keypad with hexadecimal and function keys (including hardware REset and Interrupt).
 The PMI-80 had 1 KiB of ROM (expandable to 2 KiB) and fixed 1 KiB of RWM.
 Eight (expandable to 32) I/O lines were provided for user along with complete system bus.
 Connected could be e.g., a card with a DAC of 0–12 V range.
The Netronics ELF II was an early microcomputer trainer kit featuring the RCA 1802 microprocessor, 256 bytes of RAM, DMA-based bitmap graphics, hexadecimal keypad, two digit hexadecimal LED display, a single "Q" LED, and 5 expansion slots.
 The system was developed and sold by Netronics Research and Development Limited in New Milford, CT, USA.
A cruise ship poolside theater is a giant LED display screen, ranging from around 250 to 350 square feet (33 m).
 It is complemented with a large, 50,000-80,000 watt sound system.
 The theater is usually placed facing the main swimming pool of a cruise ship.
 The theater can be used to display news, sporting events, poolside activities, concerts, and movies.
A computer monitor is an output device which displays the information in pictorial form.
 A monitor usually comprises the display device, circuitry, casing, and power supply.
 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).
 Monitors are connected to the computer via VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, Thunderbolt, low-voltage differential signaling (LVDS) or other proprietary connectors and signals.
iiyama Corporation (株式会社 , Iiyama Kabushiki Gaisha ) is a Japanese electronics company part of (株式会社マウスコンピューター "MouseComputer Kabushiki Gaisha"), producing liquid crystal display (LCD) monitors and LED display panels.
 Iiyama was founded in 1972 by Kazuro Katsuyama, named after the city of Iiyama in Nagano Prefecture, Japan.
 The company was bought by in 2006, of which Mouse Computer is part of.
 The CEO since January 2006 has been Takeichi Shinji.
An LED display is a flat panel display, which uses an array of light-emitting diodes as pixels for a video display.
 Their brightness allows them to be used outdoors in store signs and billboards, and in recent years they have also become commonly used in destination signs on public transport vehicles.
 LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes.
The TI-57 was a programmable calculator made by Texas Instruments between 1977 and 1982.
 There were three machines by this name made by TI, the first was the TI-57 with LED display released in September 1977 along the more powerful TI-58 and TI-59.
 It had 50 program steps and 8 memory registers.
 Two later versions named TI-57 LCD and TI-57 LCD-II have a LCD display, but were less powerful (ran much slower) and had much less memory: 48 bytes to be allocated between program 'steps' and storage registers.
An LED-backlit LCD is a flat panel display which uses LED backlighting instead of the cold cathode fluorescent (CCFL) backlighting used by most other LCDs.
 LED-backlit LCD TVs use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCD TVs.
 Picture quality is primarily based on TFT LCD technology, independent of backlight type.
 While not an LED display, a television using this display is called an "LED TV" by some manufacturers and suppliers.
 In the UK, the Advertising Standards Authority has made it clear in correspondence that it does not object to the use of the term "LED TV", but requires it to be explained in advertising.
The Apple Cinema Display is a line of flat-panel computer monitors developed and sold by Apple Inc. between 1999 and 2011.
 It was initially sold alongside the older line of Studio Displays, but eventually replaced them.
 Apple offered 20-, 22-, 23-, 24-, 27- and 30-inch sizes, with the last model being a 27-inch size with LED backlighting.

Question: Question: The Apple Thunderbolt Display replaced an LED display that was sold by Apple between what year and 2011?
