Wistron second display control driver

The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention. Referring to FIG. In this embodiment, the interactive virtual image display apparatus is video glasses. However, in other embodiments, the interactive virtual image display apparatus can also be a head mounted display HMD.

The interactive virtual image display apparatus includes a display unit , an image sensing module and a control unit The display unit forms a virtual image 80 in front of an eye 52 of the user.

Moreover, the display unit may further include an optical device, and when the eye 52 of the user views the display panel through the optical device, the eye 52 of the user sees the virtual image 80 corresponding to the display panel.

Alternatively, the display unit can also be a retinal projector, which projects an image to be sensed by retina onto the retina, so that the user has a feeling of seeing the virtual image The image sensing module senses the eye 52 of the user. In this embodiment, the image sensing module is, for example, a camera device. The control unit is electrically connected to the display unit and the image sensing module The control unit receives a video signal, and drives the display unit to display the virtual image 80 according to the video signal.

In this embodiment, the control unit includes a digital video decoder and a display driver The digital video decoder decodes the video signal and transmits it to the display driver , and the display driver drives the display unit to display the virtual image 80 corresponding to the decoded video signal.

In this embodiment, the number of the display units can be two, and the number of the image sensing modules can be two. The display units are respectively disposed in front of the two eyes 52 a left eye and a right eye of the user, and the image sensing modules respectively sense the two eyes 52 of the user.

Moreover, in this embodiment, the interactive virtual image display apparatus further includes a glasses frame , and the display units , the image sensing modules and the control unit are all disposed on the glasses frame The control unit has at least one operation function for example, a plurality of operation functions in this embodiment , and the operation function controls a manner that the display unit displays the virtual image The microprocessor can instruct the display unit to display a menu shown in FIG.

In this embodiment, the control unit causes the actions of the eye 52 to respectively correspond to the operation functions. For example, the actions of the eye 52 may include that the two eyes are closed for several seconds for example, between 1 second and 3 seconds, for example, 2 seconds , and then the two eyes are opened, and such action may correspond to the enter-menu function. Moreover, if the operation function is not executed for a period of time for example, 5 seconds , the control unit may instruct the display unit not to display the menu.

The actions of the eye 52 may further include closure of a single eye, and such action may correspond to the skip-to-next-item function. Now, the menu skips to the next item every a period of time until the eye 52 is opened. The action of the eye 52 may further include that the two eyes are closed for a period of time for example, 3 seconds , and then the two eyes are opened, and such action may correspond to the enter-execution function.

Moreover, the action of the eye 52 may further include that the two eyes are closed for a period of time for example, 1 second , and then the two eyes are opened, and such action may correspond to the stop-and-leave function. In this embodiment, the interactive virtual image display apparatus further includes a loudspeaker , which is electrically connected to the control unit The loudspeaker is, for example, an earphone. The control unit receives an audio signal, and drives the loudspeaker to send a sound corresponding to the audio signal according to the audio signal, and the operation function controls a manner that the loudspeaker sends the sound.

Moreover, in this embodiment, the interactive virtual image display apparatus further includes a vibration motor , which is electrically connected to the control unit The control unit can drive the vibration motor to vibrate, so as to achieve a massage effect. In this embodiment, the vibration motor can be located next to a temple of the user. When the user keeps closing the one eye, after a period of time for example, 0.

In this way, every 0. When the minute high is displayed in the digital 1 to 5, the top and bottom are also off or on at the same time. General substances can be divided into gases, liquids and solids. However, the properties of some substances do not belong to these three types. Liquid crystal is one of them. It is not a complete liquid or a complete solid. It flows like a liquid and has solid crystals.

In the natural state, the liquid crystal molecules are placed in a very thin concave Cao, and the liquid crystal molecules are arranged in the direction of the groove [3]. LCD displays work with these properties of liquid crystals. A liquid crystal material is added between the upper and lower electrodes of the LCD display, and the liquid crystal molecules are arranged in parallel, and have optical rotation, and are usually in a transparent state.

When a certain voltage is applied between the upper and lower electrodes, the liquid crystal molecules are turned into vertical alignment, and the optical rotation is lost.

Black [4]. Such is a way a screenful of information or image is displayed on a conventional liquid crystal display. Since the liquid crystal display 10 of this embodiment has pixels in the column direction, the contents of a web page cannot be entirely displayed on the screen.

The user needs to move a scroll bar at one side of the screen up and down in order to be able to view the contents of the entire web page.

Therefore, in this embodiment, if it is desired to display the entire contents of a web page on the liquid crystal display 10 , the user can issue a divide screen command via the divided screen setting user interface, e. Therefore, if it is desired to display an image video continuously in the divided screens 22 , 23 , i.

Therefore, referring further to FIG. For example, while entries of video data are retrieved in the case of displaying the single screen 21 with pixels in each line, the video driver will only retrieve entries of video data for each line of divided screen content from the video data buffer unit 12 and store the same in a row of memory addresses in the video memory 11 , i. Therefore, as shown in FIG. In other words, the video data of the two divided screens 22 , 23 are stored in sequence in two consecutive memory blocks b and c of the video memory Thus, in step 44 , when the video processing unit 14 reads video data from the video memory 11 , the video data in the memory block b will be read in sequence and displayed correspondingly on the divided screen 22 of the liquid crystal display 10 , and the video data in the memory block c is subsequently read and displayed on the divided screen Because the video data in the memory blocks b and c are successively displayed on the two divided screens 22 , 23 , when the user browses the web page, a portion of the web page that is not displayed on the divided screen 22 is displayed on the divided screen In other words, since the two divided screens 22 , 23 display continuous video data, the content of the image video displayed thereon is almost twice that displayed on the single screen Furthermore, since the two divided screens 22 , 23 display continuous video data, when the video content in one of the divided screens 22 , 23 is altered or edited, the content displayed on the other of the divided screens 22 , 23 is synchronously updated.

Similarly, referring to FIG. Therefore, when the video processing unit 14 reads video data from the video memory 11 , it will read the video data stored in the memory blocks d , e , and f in sequence and send the video data read thereby to the liquid crystal display 10 for displaying on the divided screens 61 , 62 , 63 , respectively. Since the middle divided screen 62 has a higher resolution, it is generally used as a main display area, so that the user can clearly view video content displayed on the middle divided screen Since the left and right divided screens 61 , 63 have a lower resolution, the video contents displayed thereon are roughly discernible.

The contents on the three divided screens 61 , 62 , 63 are continuous, and may be edited. Moreover, options displayed in a web page presented on the divided screens are selectable. Although the present invention has been exemplified as a notebook computer with a widescreen display, it can be implemented in a flat panel display of a conventional desktop computer, and is not limited to the preferred embodiment described herein. In addition, the preferred embodiment is not limited to the screen dividing modes of dividing a screen into two and three divided screens as described hereinabove.

Manufacturers of notebook computers or desktop computers may design other screen dividing modes according to user requirements so as to provide users with better displaying effects. I have uninstalled and reinstalled the drivers many times with no advances. Any ideas would be appreciated. Thanks, Arthur. This thread is locked.
