A system and method for increasing displaying time of online advertisements. Upon receiving a search request, a search engine identifies a list of search results and displays them on one side of a result page. The search engine also obtains a list of advertisements and displays them on the other side of the result page. When a user scrolls down to look at search results at a lower portion of the result page, the list of advertisements are moved down, following the movement of the screen. Thus, at least a part of the list of advertisements continue to be displayed on the current screen. Since online advertisements are visible to the user for a longer time, there are more opportunities for the online advertisements to get the user's attention, and consequently more opportunities for the user to click on an advertisement. Thus, the efficiency of online advertising may be improved.

A large screen information interactive system and method are disclosed, including a computer 3, a projector 4, a pointer equipment 2, and an interactive whiteboard 1 including at least one display panel 6 on the same plane and at least one electronic writing board 5 used for sensing and receiving an operational signal of the pointer equipment 2. The at least one electronic writing board 5 is connected with the computer 3 through a serial port, a USB port, a wireless communication module, or a bluetooth module. The signal of the pointer equipment 2 collected from the electronic writing board 5 is processed by the computer 3. A processed displayed image is projected onto the interactive whiteboard 1 by the projector 4. When one point on the electronic writing board 5 is written, position and state information signals of the written point are transferred to the computer for converting, and the data is processed according to display attributes and operational commands. A whiteboard coordinate is converted into a screen coordinate corresponding to a display. A state of the pointer equipment 2 is converted into a mouse state, so as to updating the screen data. Screen signals are projected onto the interactive whiteboard 1 by the projector 4. Therefore, display and writing problems with an ultra-large screen are resolved, extending the application scope of the interactive whiteboard.

A color display device including: at least one spatial light modulation element forming a display picture by modulated light obtained by modulating illumination light, a color sequential light generation device changing in a time series the illumination light or the modulated light into multiple groups of different color lights in one frame of a display period of the display picture, a control device controlling the spatial light modulator, and a color sequential light generation device based on the input picture data. The control device controls the spatial light modulator and the color sequential light generation device to change the ratio of the display time of each color of the reflected light time-shared in the display period of the frame depending on the character and / or the set value of the input picture data.
