Embodiment Construction

[0021] According to the above, a humanized display brightness automatic control device and method thereof are provided. The display brightness automatic control device and its method can dynamically adjust the brightness of the screen according to the human body fatigue index and the environmental factors of dry eyes, so that the physiological state of the user's eyes is more comfortable. In the following description, an example structure and an example control method of the above-mentioned display brightness automatic control device will be introduced. For the sake of easy understanding of the described embodiments, a number of technical details will be provided below. Of course, not all embodiments require these technical details. Meanwhile, some well-known structures or elements are only drawn schematically in the drawings to appropriately simplify the contents of the drawings.

[0022] Please refer to figure 1 , figure 1 A notebook computer provided with an automatic d...

Abstract

Provided are an automatic control device and method for brightness of a display. Here, the human body fatigue index and the environmental factor of dry eyes are used as the index basis to dynamically adjust the brightness of the display. The aforementioned human fatigue index uses an index obtained by analyzing heart rate variability, while the environmental factor of dry eyes uses ambient carbon dioxide (CO2) concentration as an index.

Description

technical field [0001] The invention relates to a display brightness control device and a method thereof, in particular to an automatic display brightness control device and a method thereof. Background technique [0002] The use and operation of computers has become an inevitable job in today's digital age. With the fierce global competition, the time spent using computers is increasing day by day, and the related health problems caused by computers are also more and more plaguing modern people. The eyes are the window to the soul, but long-term focus on the use of computers, ignoring the number of blinks or poor air quality will affect the normal lubrication of the eyeballs, and even cause eye inflammation or retinal vascular occlusion in severe cases. The relationship between eye health and computer use has become a problem that has to be faced squarely. At present, studies on sick building syndrome and computer terminal syndrome have shown that carbon dioxide concentrat...
