Trident Microsystems

Trident Microsystems Inc. was an American^[5] fabless semiconductor company that became in the 1990s a well-known supplier of integrated circuits (commonly called "chips") for video display controllers used in video cards and on motherboards for desktop PCs and laptops. In 2003, it transformed itself into being a supplier of display processors for digital televisions, and primarily LCD TVs starting from 2005, at a time when the global LCD TV market started showing strong growth.

It filed for bankruptcy protection in January 2012^[6] and the delisting of its common stock from the NASDAQ stock market was announced shortly thereafter.^[7]

Established in 1987, Trident gained a reputation for selling inexpensive (for the time) but slow SVGA components. Many OEMs built add-in-boards using Trident VGA chipsets. As the PC graphics market shifted from simple framebuffer displays (basic VGA color monitor and later multi-resolution SVGA output) to more advanced 2D hardware acceleration such a BitBLT engine and color-space conversion (not to be confused with 3D hardware-acceleration), Trident continued its strategy of selling modestly performing chips at compelling price points. In the mid-1990s, the company (briefly) caught up with its main competition: the TGUI-9680's feature-set was comparable to the S3 Graphics Trio64V+, although the Trio64V+ outperformed the 9680 in true-color mode.

The rapid introduction of 3D graphics caught many graphics suppliers off guard, including Trident. It was not until the late 1990s that Trident finally released a competitive chip, the TGUI-9880 (Blade3D). By this time, Trident's reach had once again retreated to the low-end OEM market, where it was crowded by ATI, S3, and SiS.

Meanwhile, in the laptop market, Trident was an early pioneer of embedded DRAM, a semiconductor manufacturing technique which combines a graphics-controller and framebuffer memory on a single chip. The resulting combo-chip saved precious board-space by eliminating several RAM chips normally required for framebuffer storage as well as providing other advantages, offset by a higher manufacturing cost-per-bit. In this market it competed with NeoMagic.

Although Trident enjoyed some success with its 3DImage and Blade3D product-lines, the entry of Intel into PC graphics signaled the end of the bottom-end, graphics-chip market. Trident partnered with motherboard chipset suppliers several times to integrate its graphics technology into a motherboard chipset (i.e. ALi CyberALADDiN, VIA MVP4), but these achieved marginal success.

Faced with a contracting market and rising research and development costs (due to the increasing sophistication of 3D-graphics rendering), Trident announced a substantial restructuring of the company in June 2003. In late 2003, XGI completed the acquisition of Trident's former graphics division, completing the transformation of the company into one focusing on DTV products. From this point on, Trident's research and development was mainly concentrated at its facilities in Shanghai, China, and a fully owned 115,000-square-foot research and development facility in Shanghai was completed in 2007.^[1]

Trident quickly gained success in the LCD TV chip market in 2005, providing competitive advantages in image quality and chip integration, outcompeting incumbent flat-panel IC leader Genesis Microchip and supplying chips to leading LCD TV brands Sony and Samsung, and later Sharp and Philips.^[1] Its revenues increased from 69ドル million in the fiscal year ended June 30, 2005, to 270ドル million in fiscal year 2007, when it had net income of 30ドル million.^[1] This success allowed the company to increase its cash reserves to more than 200ドル million by 2008.^[1]

After an investigation into accounting irregularities relating to stock options, in November 2006 the company's chairman and CEO resigned,^[8] which was followed by the departure of further key personnel, including its president and former vice president of engineering in early 2008.^[1]

By 2008 as DTV manufacturers started integrating more functionality (such as motion compensation/estimation and MPEG decoding) into a single chip, its fortunes turned and its sales quickly declined to 76ドル million in fiscal year 2009, for which it posted a loss of 70ドル million.^[9] The primary competitors taking away market share from Trident at the time were MediaTek, MStar Semiconductor, Zoran Corporation and in-house chip design at Samsung and other LCD TV manufacturers, while ST Microelectronics (who had acquired Genesis) remained a significant player.^[10]

Under new management, in May 2009 Trident completed the acquisition of selected assets of the frame rate converter (FRC), demodulator and audio product lines from TDK-Micronas.^[11] In October 2009 Trident announced a deal with NXP Semiconductors to transfer NXP's TV and STB businesses to Trident, with NXP becoming a significant shareholder.^[12] The deal was closed in February 2010.^[13]

The Micronas and NXP acquisitions involved a substantial and diverse product portfolio and a large number of employees in widely dispersed operations in the U.S., Europe, Asia, and other locations.^[14] The acquisitions significantly increased the Trident's revenues to 557ドル million in 2010 but also greatly worsened its profitability and cash flow, resulting in a loss from operations of 173ドル million in 2010 and net loss of 129ドル million.^[14] According to unaudited results for 2011, revenues decreased by 46.5% in 2011, resulting in another net loss of 150ドル million.^[15]

On January 4, 2012, Trident filed for Chapter 11 bankruptcy protection appointing Entropic Communications as the stalking horse bidder.^[6] In February 2012, Entropic announced it would buy Trident's set-top box chip business for 60ドル million.^[16] In June 2012, Cambridge Silicon Radio paid 1ドルM for Trident's audio products.^[17] Around the same time Sigma Designs purchased Trident's remaining TV chip business.^[18]

Trident common shares traded on the NASDAQ stock market from its initial public offering on December 16, 1992^[19] to 2012.^[7] The stock split two-for-one on 21 November 2005^[20] and reached a high of 31ドル.07 on 19 April 2006,^[20] representing a market capitalization of approximately 1ドル.9 billion.^[a] It later declined substantially including a large drop on 26 October 2007.^[20] The stock dropped below 3ドル in September 2008 and it would never close above 3ドル again.^[20]

In November 2005, Trident announced that its founding chairman and CEO, who owned 10% or more of the company's shares,^[21] had established a pre-arranged trading plan to sell up to 1,250,000 pre-split shares of common stock.^[22]

In November 2006, Trident announced the resignation of its founder and CEO following an investigation by a special committee into back-dating of stock option grants, and announced that it would restate its financial results for the period 1994 to 2006 to reflect non-cash charges for stock based compensation expense.^[8]

The U.S. Securities and Exchange Commission in 2010 announced a settlement with Trident's founder and former CEO and with Trident's former chief accounting officer, relating to a complaint alleging illegal back-dating of stock options in the period from 1993 to 2006. As part of the settlement, the former CEO agreed to be barred for five years from serving as an officer or director of any company registered with the SEC and to pay a 350,000ドル penalty and a disgorgement (representing the benefit gained from the back-dating of stock options) of 817,500ドル payable to Trident.^[23] In 2011, Trident reached a settlement with its former CEO resulting from a derivative shareholder suit that resulted in payment of 9ドル.4 million to the company.^[24]

The SVP-EX product family (described as Trident's fifth-generation video technology) was introduced in 2004^[33] and ramped to significant volume in 2005 as top-tier OEMs Sony and Samsung widely adopted the chip in their new LCD TV models during a time when LCD TV demand grew significantly.^[34] It offered advantages in image quality and chip integration compared to competitive solutions, featuring ten-bit color component precision in ADCs, color decoder, deinterlacer, scaler, color processor (image enhancement) and display interface, and a single unified framebuffer.^[33]

The SVP-PX (described as featuring Trident's sixth-generation video technology) was the successor of the SVP-EX, featuring an integrated HDMI interface^[35] and contributed more than 50% of the company's revenue by Q2 2006.^[36]

The SVP-LX (with sixth-generation video technology) was Trident's first chip to support Full HD for high-end televisions.^[1]

The SVP-CX (sixth-generation) was a cost-reduced version of the SVP-PX for lower-end LCD TVs with a resolution up to 1366x768p.^[1] It was widely adopted by Philips.^[37]

The SVP-UX and SVP-WX integrated Trident's first-generation motion compensation/motion estimation technology.^[1]

The HiDTV platform, which had a long development history, was Trident's first generation fully integrated DTV SoC integrating MPEG2 decoding, transport stream demultiplexer, and descrambler with the video processor functionality of earlier products.^[1] The HiDTV Pro platform was Trident's second-generation integrated DTV SoC platform,^[1] with several variants integrating different Trident video processors.^[1] Both HiDTV product lines suffered from delays and slow adoption and it was only after the acquisition of Micronas product lines that it was able to win a significant SoC design win at a major OEM for production in 2010.^[38]

After the Micronas and NXP acquisitions in 2009, Trident acquired a diverse range of chip products for applications ranging from digital TVs to various types of set-top box, including the FRC (motion-estimation/compensation) chip family from Micronas that was widely used in high-end televisions. At this point Trident possessed a fragmented, overlapping portfolio of products and technology resulting from long-term independent development efforts (stemming from NXP, Micronas and Trident itself), with several architecturally distinct solutions targeting the same application (such as ME/MC chip, DTV video processor and integrated DTV SoC).^[39]
