Problems solved by technology

This is obviously easy to cause visual fatigue and miss a lot of visual enjoyment, and the high power consumption brought by high brightness is contrary to the energy-saving society advocated today. In order to solve the above problems, the current market consists of Netbook, LX800, UMPC and other portable and easy-to-move microcomputer products mostly use an EC embedded controller and the method of adding a control program in the BIOS to realize the PWM function of controlling the backlight display on the hardware.
[0005] However, there is no EC available in industrial single-board computers, so the current LX800 industrial single-board computers of various manufacturers do not provide PWM functions, which obviously cannot meet the needs of users very well.

Abstract

The invention discloses a single-board computer comprising a chip set, a board-carrying internal memory, an interface and a bus. The single-board computer is characterized in that the PWM control of the backlight of a liquid crystal panel can be realized by the matching of a PWM1 functional pin of a super input / output chip of a Super I / O chip SCH3114 and a BIOS program, so that the single-board computer is more intelligent, and the power management is more scientific.

Description

technical field [0001] The invention relates to the field of single-board computers, in particular to a single-board computer for industrial automation control. Background technique [0002] In 2005, AMD released the new AMD Geode LX 800 processor. The AMD Geode LX800 processor adopts the general industry standard x86 architecture. It is an embedded CPU with the full functionality of a desktop CPU and can be used in embedded or mobile devices. [0003] The AMD LX 800 processor supports Microsoft Windows XP and XP embedded operating systems, and consumes less than 1W. It can run on low-power, fanless and portable mobile devices. The AMD LX 800 processor supports the performance of the x86 architecture, and expands the performance and functions of the x86 architecture. Because the x86 architecture has low power consumption and good execution performance, the AMD LX800 processor is widely used in Netbook, UMPC, GPS and industrial Take control of the scene. [0004] Driven by...
