Abstract:
A display module includes a display panel having a substrate as a base at least provided with conductive circuits and external connection pins; and a circuit board electrically connected with the external connection pins of the substrate through a conductive material for driving the display panel. The substrate could be electrically connected with the circuit board without the need of flexible printed circuit boards, thereby simplifying structure of the display module.

Abstract:
A method for driving a plasma display panel (PDP). The PDP includes a first electrode and a second electrode. Initially provide the first electrode with a first voltage V1. Next, provide the second electrode with a second voltage V2 that is higher than the first voltage V1 during a first time interval. Then, provide the second electrode a third voltage V3 that is lower than the first voltage V1 during a second time interval. In the first time interval, a first voltage difference D1 between the first electrode and the second electrode equals the second voltage V2 minus the first voltage V1. During the second time interval, a second voltage difference D2 between the first electrode and the second electrode equals the third voltage V3 minus the first voltage V1.
Abstract:
An energy recovery circuit of a plasma display panel is disclosed, which can drive the sustain electrode of the plasma display panel during the sustain period. The energy recovery circuit includes a voltage source which can store electrical energy, a first channel for raising the voltage of the sustain electrode to high potential, a second channel for pulling the voltage of the sustain electrode down to ground, and other auxiliary circuits. When the first channel is turned on, the voltage source can transmit electrical energy to the sustain electrode. When the second channel is turned on, the voltage source retrieves the electrical energy from the sustain electrode. Thereby the sustain electrode is driven between high potential and ground. Moreover, the first channel and the second channel can share a part of common channel.
Abstract:
A plasma display panel (PDP) has a front and a back substrate mounted together, with a gap between them. Barrier ribs are positioned within this space of this gap, and they define a series of discharge space groups. Each discharge space group has a first, second and third discharge space for red, green and blue emitting phosphors. Within these discharge spaces are traverse ribs. The lengths of these traverse ribs are adjusted to change the relative proportions of phosphor surface areas, and thus adjust the color temperature of the PDP.
Abstract:
A device and method for adjusting backlight brightness employed in a display. The device has a buffer, a counter, and a comparator. The buffer receives and stores an image data of a frame. The counter receives the image data and obtains an image-loading value of the image data. The comparator is coupled to the counter and compares the image-loading value with a preset image-loading value. The comparator outputs a control signal indicating the comparison result to a backlight module to adjust the brightness of the backlight module.
Abstract:
A three-dimensional display includes a first display module, a second display module, a light-combining module and a view-scanning layer. The first display module provides a first display image. The second display module provides a second display image. The light-combining module is disposed in a first transmission path of the first display image and a second transmission path of the second display image. The first transmission path and the second transmission path after the first light-combining module have the same direction. The view-scanning layer receives the first display image transmitted along the first transmission path and the second display image transmitted along the second transmission path and respectively projects a part of the first display image and a part of the second display image onto a first view direction and a second view direction.
Abstract:
A pixel driving circuit of this invention utilizes a storage capacitor and an active loading circuit to serve as a pixel data storage buffer for each pixel. The pixel driving circuit of this invention can write the whole-panel pixel data for a next frame in these storage buffers during the illuminating time of a backlight. When changing the frames, the whole-panel pixels synchronously read the pixel data pre-stored in these storage buffers. As a result, the write-in time of the whole-panel pixel data is reduced and the illuminating time of the backlight is relatively increased.
Abstract:
A pixel structure of a display device and a method for driving the same are provided. The pixel structure has a pixel capacitor, a switch, a pre-write unit and a reset unit. The pre-write unit is coupled to the switch for pre-writing display data therein when the switch is turned on. The reset unit is coupled between the pre-write unit and the pixel capacitor for resetting the pixel capacitor. When the pixel capacitor is reset, the display data is pre-written to the pre-write unit. After the pixel capacitor is reset and ready for display, the pre-written display data is written to the pixel capacitor.
