Embodiment
With reference to figure 1, the power saving display unit at portable intelligent of the present invention terminal is made up of display controller, row driver, line driver, display floater, mode switch module, video decode module.They act on respectively:
Display controller is used for row driver, line driver are controlled; The display mode setting of response modes handover module forms the demonstration output that is fit to this pattern; According to the video decode module, form control signal and digital signal output to row driver, line driver.
Mode switch module is used to the various modes configuration that realizes that power saving of the present invention shows; Switching between the completion pattern; Be used to be provided with the viewing area of being lighted; And the driving display controller, and then control and configuring arrange driver and line driver be to the driving of display floater, the demonstration output that makes corresponding display light and form to meet this viewing area
Display floater forms two or above viewing area through physical division or virtual division.With reference to figure 1, the quantity of viewing area can be decided according to screen size and resolution, and under the preferable case, it is suitable being divided into two or three viewing areas.
Below, in conjunction with accompanying drawing, illustrate the viewing area and divide:
With reference to figure 4, be a display floater that resolution is 800*1280, like Samsung mobile phone Galaxy Note, display screen resolution is 800 * 1280 pixels, screen is 5.3 inches.Through the inventive method, the display floater of 800*1280 can be divided into three viewing areas, and resolution respectively as follows: the first viewing area 800*480, the second viewing area 800*480, the 3rd viewing area 800*320.With reference to figure 5, be a display floater that resolution is 480*800, can be divided into two viewing areas according to resolution, i.e. the first viewing area 480*320, second viewing area, 480*480.With reference to figure 6, be a display floater that resolution is 320*480, can preferably be divided into two viewing areas, i.e. the first viewing area 320*240, second viewing area, 320*240.In the preferred version; First viewing area can preferentially be divided according to the common resolution of mobile phone; Be smart mobile phone like 800*480,480*320,320*240 and extensively adopt screen resolution; Under the battery saving mode, can obtain the good compatibility that shows, specifically can divide according to display floater size and resolution through first viewing area.Physical division or virtual division can be passed through in the viewing area of display floater.Wherein physical division is meant in display floater printing process; Display floater is used to realize that the structure sheaf that shows has and divided the identical independent displaying unit of quantity, viewing area, each independently display unit through independently display driver interface or the identical driving interface of showing drive demonstration.Different independent displaying unit seamless is combined into a complete display floater.Virtual division is meant the control model through the change display controller, or directly changes the type of drive of line driver or row driver, and a display floater is carried out the method that control was lighted and shown in the part.What virtual division changed is not display panel structure, but improves and the realization of display controller chip programming through drive circuit.
With reference to figure 1, the portable intelligent terminal system is provided with the viewing area (under the battery saving mode, only lighting first viewing area) of being lighted through mode switch module, and mode switch module notice video decode module is decoded according to the resolution of this viewing area; After video data is input to display controller; Display controller is controlled the row that is scanned, if battery saving mode through the control line driver; The display unit that then only scans and drive first viewing area shows, promptly only lights first viewing area and shows.If be non-battery saving mode; Then can light all viewing areas simultaneously, show through original size of display floater and resolution according to user's selection; Can be some viewing areas of lighting simultaneously wherein, be combined to form a viewing area bigger than battery saving mode.
With reference to figure 2, with respect to Fig. 1, this power saving display unit has a plurality of line drivers.The viewing area quantity of the quantity of line driver and display floater equates.Display floater is divided through the physical segmentation method has independently display unit, and each independent displaying unit is as a viewing area.Each viewing area has the independent displaying driving interface, and each viewing area drives through line driver independently.Promptly turntable driving is carried out through first line driver in first viewing area, and turntable driving is carried out through second line driver in second viewing area.With reference to figure 3, row driver can shared same driver, also can consider through each independently row driver advance.According to the size of display floater, the viewing area of display floater is divided and can laterally be divided, and also can vertically divide.
In sum, carrying out the method that power saving shows through the power saving display unit at this portable intelligent terminal may be summarized to be:
At first the display floater at portable intelligent terminal forms two or above viewing area through physical division or virtual division; Under the battery saving mode, through changing the drive pattern of line driver or row driver, only lighting wherein, the part viewing area is used to show that output is to reduce the power consumption of display floater; When the user selected display mode through mode switch module after, the display controller at portable intelligent terminal control line driver or row driver to be lighting the pairing viewing area of this display mode, and form the output that is fit to the viewing area demonstration that this quilt lights.Under the normal mode, can show, also can light the composition of some of them viewing area, form the different outputs that show size and resolution through lighting whole viewing areas.Under the non-battery saving mode, display controller control line driver and row driver are to light all viewing areas, and the whole display floater at portable intelligent terminal is used for the whole output that shows.
The viewing area respectively through line driver independently or independently row driver drive; Perhaps the viewing area adopts different drive patterns to drive through common line driver and row driver respectively.
Other details of apparatus of the present invention and method can be implemented with reference to prior art.During practical application, can realize that portable intelligent terminal such as mobile phone is equipped with the needs of large-screen, simultaneously through different screen ignition mode, reaches the display floater purpose of power saving.
