Problems solved by technology

[0012] However, in the prior art, in the power state of the battery mode, the power consumption is high, and there is a problem of shortening the continuous use time of the battery.
At the same time, when the remaining battery power is low, sampling is performed at a certain sampling rate, so there is a problem of rapid power consumption

Embodiment Construction

[0039] Hereinafter, implementations of the touch screen power saving device and method thereof of the present invention will be described in more detail with reference to the accompanying drawings.

[0040] The touch screen power saving device of the present invention has the following features: monitor the battery residual power of portable information equipment (such as notebook computers, smart phones, personal portable terminals, etc.) with a touch screen, and automatically control the sampling device to sample ratio, thereby reducing power consumption.

[0041] Although the existing touch screen device manages the sampling rate of the touch screen with one numerical value, the touch screen power saving device of the present invention provides two touch screen sampling modes according to the power mode (battery mode or AC adapter mode) of the computer system.

[0042] Specifically, the second mode is a mode for maintaining a constant sampling rate of the touch panel sampli...

Abstract

A power-saving function for a touch screen device provides efficient use of power, such as from a battery for a portable device. The touch screen device may include a sampling unit for digitizing an input to the touch screen. The power-saving function is provided with a battery level-monitoring unit for monitoring a battery level, and a sampling rate controller for controlling a sampling rate of the sampling unit based on the battery level monitored by the battery level-monitoring unit.

Description

technical field [0001] The present invention relates to a touch screen power saving device and a method thereof, in particular to a touch screen power saving device and a method thereof capable of controlling the sampling rate of a touch screen according to the remaining battery power of a portable information device to minimize power consumption. Background technique [0002] Today, due to the development of information communication technology, portable information devices that can detect required information anytime and anywhere have been developed. One of its representatives is a personal portable terminal. Personal portable terminals have evolved from the functions of simply managing personal schedules and contact addresses. PDAs with built-in wireless communication modules can not only make voice calls, but also use wireless communication networks to access the Internet, and can send and receive emails or faxes. Wait. [0003] Portable information devices such as per...
