Trident Microsystems is a supplier of display-processors for flat panel displays (plasma, LCD, etc.). At one time, Trident was also a supplier of PC graphics chipsets and sound controllers.

Late in the 1980s, Trident (along with Oak Technologies) gained a reputation for selling inexpensive (for the time) but slow SVGA chipsets. Many OEMs built add-in-boards using Trident VGA chipsets. As the PC graphics market shifted from simple framebuffer displays (basic VGA colour monitor output) to more advanced hardware acceleration (multi-resolution, SVGA output; not to be confused with 3D hardware-acceleration), Trident continued its strategy of selling modestly performing chips at compelling pricepoints. 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-RAM on a single chip. The resulting combo-chip saved precious board-space by eliminating several RAM chips normally required for framebuffer storage.

Although Trident enjoyed some success with its 3DImage and Blade3D product-lines, the entry of Intel into PC graphics signalled 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 PLE133), 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 in June, 2003, a substantial restructuring of the company.

In late 2003, XGI completed an acquisition of Trident's former graphics division.
