Tseng Laboratories, Inc.（也称为Tseng Labs或TLI，在台湾过去称为曾氏）是一家研制显示芯片与IBM兼容PC用控制芯片的公司，其总部位在美国宾夕法尼亚州的Newtown，该公司约在1980年代开始活跃，之后在1997年退出显示、视频、绘图方面的业务。

Tseng最为人所熟知的产品是Tseng Labs ET3000、Tseng Labs ET4000以及Tseng Labs ET6000等VGA兼容的显示芯片，此在1990年－1995年（Microsoft Windows 3.x时代）间相当普及与受欢迎。且值得注意的是，该公司的ET4000家族能在使用ISA总线下进行高速传输，而且还是用传统的DRAM型显存（Framebuffer）。

Tseng Laboratories, Inc. (also known as Tseng Labs or TLI) was a maker of graphics chips and controllers for IBM PC compatibles, based in Newtown, Pennsylvania, and founded by Jack H-N Tseng.

Founded in 1983, Tseng Labs' first product was designed to allow IBM PCs to run the CP/M Operating System. When an OEM deal for that product was cancelled, TLI introduced a combination multifunction and graphics, called Ultrapak, which upgraded IBM PC and XT compatible computers with some features of an IBM AT. Ultrapak also foreshadowed Tseng Labs penchant for enhancing graphics - by providing IBM Monochrome Display Adapter (MDA) and Hercules Graphics Card (HGC) compatibility along with their own special 132 column text modes. These extended text modes created a successful niche for TLI - the cards were popularly used by corporations for PCs that also emulated mainframe terminals that displayed 132 columns. The UltraPAK Short (a graphics-only version of UltraPAK) was the base design for the DFI MG-150, which was reported to be the best selling MDA/HGC compatible card of all time.
