Abstract

The invention discloses a power-saving display method of a portable intelligent terminal, which is characterized in that a display panel of the portable intelligent terminal is divided into two or more display areas through physical division or virtual division; in a power-saving mode, through changing the drive mode of a row driver or a line driver, only part of the display areas are lightened for displaying outputs so as to reduce the power consumption of the display panel; meanwhile, the invention also discloses a power-saving display device of a portable intelligent terminal, which comprises a display controller, a row driver, a line driver and a display panel, and the power-saving display device is characterized in that the power-saving display device is divided into two or more display areas through physical division or virtual division; and the power-saving display device also comprises a mode switching module, the mode switching module is used for setting lightened display areas, driving the display controller, and then controlling and configuring drives of the row driver and the line drive to the display panel, so that a corresponding display area is lightened, and a display output complying with the display area is formed.

Description

technical field [0001] The present invention relates to planar display technology, more specifically to a power-saving display device and method applied to portable intelligent terminals. Background technique [0002] At present, there are more and more smartphones, with higher and higher hardware configurations, larger and larger screens, and thinner and thinner screens. With the emergence of touch operating systems such as Android, large-screen mobile phones are blooming everywhere. [0003] Large-screen mobile phones or portable smart terminals are faced with an important problem, the power consumption is large, and the battery generally can only be used for about one day. In addition, the power consumption of the screen accounts for a large proportion of the power consumption of the entire terminal, which can reach 50% or more. [0004] The large screen setting of the mobile phone is mainly to improve the user's experience in browsing the web, enjoying high-definition ...
