About aforementioned and other technology contents, characteristics and effect of the present invention, in the detailed description of a following cooperation preferred embodiment with reference to the accompanying drawings, can clearly present.

Consult shown in Figure 1, it is a preferred embodiment of electronic installation of the present invention, the electronic installation of the present embodiment is as example take a notebook computer 100, it has a length * wide ratio is 1600 * 800 wide screen liquid crystal display 10, and Figure 1 shows that this notebook computer 100 shows the main circuit square frame of divided frame in order to control this liquid crystal display 10, comprising a video memory 11, a video data deposit unit 12, a CPU (central processing unit) 13 and a video processing unit 14.

Video memory (video RAM generally is called for short VRAM) 11 stores finally will be sent to video (image) data that liquid crystal display 10 shows.

Video data deposit unit 12 may be primary memory or hard disk, its temporary original video (image) data.

Be loaded with a video driver and a divided frame in the CPU (central processing unit) 13 and set application program, after this divided frame setting application program is performed, can produce a divided frame in liquid crystal display 10 and set the user interface, set the frame numbers that to cut apart for the user, namely set the divided frame pattern, for example set the pattern 1 of two divided frames or set pattern 2... of three divided frames etc., video driver then can reach the respectively corresponding resolution of divided frame of this pattern according to the divided frame pattern that the user sets, video data in suitable this video data deposit unit 12 of acquisition also deposits in the continuous position of video memory 11, that is the video driver of the present embodiment can be according to the quantity of divided frame and the resolution of each divided frame, the continuous video data of the resolution of corresponding each divided frame is taken out and deposits the Coutinuous store position of video memory 11 from video data deposit unit 12, by this, video processing unit 14 sequentially reads the continuous video data in this video memory 11, and sequentially deliver to according to the divided frame orientation when showing in each divided frame of this liquid crystal display, just can allow these divided frames show continuous image (video).Below will further illustrate.

As shown in Figure 2, because the resolution of liquid crystal display 10 is 1600 * 600 pixels, when only showing single picture 21, capturing 1600 * 600 video datas in the video pictures data that video driver in the CPU (central processing unit) 13 can be kept in from video data deposit unit 12 also sequentially deposits in the memory block (a) of video memory 11, as shown in Figure 3, video data can sequentially be deposited in the address (1 of video memory 11 line by line, 1) (1600,1), (2,1)～(1600,2), ... until (600,1)～(1600,600), therefore when video processing unit 14 accessing video storer 11, also can be line by line, from the address (1,1)～(1600,1), (2,1)～(1600,2), ... begin sequentially sense data and deliver to liquid crystal display 10 to show, that is, make the video data that stores in each memory address in the memory block (a) be presented at each corresponding pixel of liquid crystal display 10.More than be a kind of way of general liquid crystal display when showing single picture.

But as user during at browsing page, because a webpage accounts for 1280 (OK) * 800 (row), so display needs 1280 (OK) * 800 (row) could show a web page contents fully at least, and the liquid crystal display of the present embodiment is because only have 600 row, so can't be in single picture the content of a webpage of complete demonstration, the scroll bar (scroll bar) that the user must move up and down the picture side just can be seen the content of whole webpage.

So, in the present embodiment, if want liquid crystal display 10 to show complete web page contents, the user can set the user interface by above-mentioned divided frame, send a divided frame instruction, when for example requiring 2 divided frame of notebook computer 100 display case such as halves on liquid crystal display 10, as shown in Figure 4, owing to liquid crystal display 10 will be divided into two picture displies, therefore the resolution of each picture can become and only has 800 * 600 pixels, if so want image (video) in divided frame, to show continuously, that is when allowing divided frame can show continuous two pages of images (video) data, CPU (central processing unit) 13 must be rearranged the storage address of video data in video memory 11.

Therefore, shown in the step 41 of the divided frame flow for displaying of Fig. 5, when the video driver of CPU (central processing unit) 13 is received above-mentioned divided frame instruction, video driver carry out step 42, resolve this divided frame instruction, to learn divided frame quantity and the resolution of the divided frame pattern institute wish generation that the user sets, execution in step 43 again, depending on the quantity of divided frame and the resolution of each divided frame, again capture the video data in the video data deposit unit 12, when for example originally showing single picture, delegation's picture has 1600 pixels, so need 1600 video datas of acquisition, but the delegation of each present divided frame only has 800 pixels, so video driver only can the video data from video data deposit unit 12 in the video data of 800 of acquisitions deposit in delegation's memory address of video memory 11, that is, every delegation of video memory 11 only deposits (1,1)～(800,1) totally 800 addresses, so as shown in Figure 6, first divided frame can take video memory 11 memory block (b) the (1,1)～the (600,800) address, and second divided frame can take video memory 11 memory block (c) the (601,1) address～(1200,800).That is the video data of two divided frames sequentially is stored in two the continuous memory block (b), (c) of video memory 11.

By this, such as step 44, when graphic process unit 14 reads video memory 11, the video data of memory block (b) can sequentially be read and corresponding being presented in the divided frame 22 of liquid crystal display 10, and then the video data of memory block (c) is read and is presented in another divided frame 23 by graphic process unit 14.And because video data is presented in two divided

frames

22,23 continuously, so when user's browsing page, the part webpage that does not show in one of them divided frame 22 then can then be presented in another divided frame 23, that is, two divided

frames

22,23 are owing to being to show continuous video data, so can show than single picture and Duo one times image (video).

And, because two divided frames 22, the 23rd show continuous video data, so when the video content in the picture wherein was changed or is edited, the content that shows in another divided frame also can be upgraded synchronously.

Similarly, again referring to shown in Figure 7, when the user sets the user interface by divided frame, when requiring to show 3 divided frame, the video driver of CPU (central processing unit) 13 can be divided into display frame a left side as shown in Figure 7, right picture is little, three divided frames 61 that midway film is large, 62,63, it is left, part on the right side and cut

picture

61,63 resolution is similarly 288 * 600 pixels, and the resolution of midway film 62 is 1024 * 600 pixels, therefore, video driver will according to the different resolution of three divided frames, capture respectively 288 * 600 from video

data deposit unit

12,1024 * 600 and 288 * 600 totally three continuous pictures video data and sequentially deposit continuous three memory block (d) of video memory 11 as shown in Figure 8 in, (e), (f) in.So, when Graphics Processing Unit 14 reads video memory 11, will sequentially read the video data that stores among memory block (d), (e), (f) and also deliver to respectively demonstration in the divided

frame

61,62,63 of liquid crystal display 10.And because the resolution of middle divided frame 62 is higher, so normally with middle divided frame 62 as main display frame, the user can see clearly video content in middle divided frame 62, and left and

right picture

61,63 is because resolution is lower, so general display of video content, but three divided

frames

61,62,63 content all are continuous, can be edited, and the option in the shown webpage of each divided frame can be controlled and clicks.

Though the present embodiment is the notebook computer with wide screen is example, also can be embodied in the employed flat-panel screens of general desktop PC, is not limited with the present embodiment.

In addition, the present embodiment also is not limited to two above-mentioned divided frame patterns and three divided frame patterns, the exploitation dealer of notebook computer or desktop PC can design other different divided frame patterns voluntarily according to user's demand, to offer the better display effect of user.
