Dual Scan, also known as dual-scan supertwist nematic or DSTN, is an LCD technology in which a screen is divided into two sections which are simultaneously refreshed giving faster refresh rate than traditional passive matrix screens. It is an improved form of supertwist nematic display that offers low power consumption but inferior sharpness and brightness compared to TFT screens. For several years (late '90s to early 2000s), TFT screens were only found in high-end laptops due to them being more expensive and lower-end laptops offering DSTN screens only. This was at a time when the screen was often the most expensive component of laptops. The price difference between a laptop with DSTN and one with TFT could easily be $400 or more. However, TFT gradually became cheaper and has essentially captured the entire market.
Dual scan display panel driver
A display panel driver has two driver circuits that drive separate halves of a display panel. Each driver circuit occupies a separate integrated circuit chip. The driver has a screen saving mode in which each driver circuit displays an independent screen saving image that moves in synchronization with a timing signal. The timing signal is generated in one driver circuit and transmitted by a chip-to-chip interface to the other driver circuit. The two screen saving images are thereby coordinated to create what appears to be a single screen saving display.

An apparatus and method for operating a plasma display panel (PDP) capable of removing or preventing peaking noise or voltage spike is disclosed. After substantial video data is completely recorded in the address electrode and / or after the last scan pulse or signal on the last scan electrode, the apparatus floats the address electrode or maintains the address electrode at a predetermined voltage, such that it prevents peaking noise from being received from the scan electrode and the sustain electrode, resulting in no erroneous discharge. As a result, the apparatus improves an image quality of the PDP, and increases operation efficiency of the PDP including use of single scan rather than dual scan.

Self light emission display device
InactiveUS20050104822A1Static indicating devicesElectroluminescent light sourcesLuminous intensityScan line
A self light emission display device which substantially enables dual scan drive by one data driver comprises a plurality of scan lines K1, K2, . . . which are arranged in a horizontal direction, a plurality of data lines A1, A2, . . . which intersect these scan lines and are arranged in a vertical direction, and a plurality of light emitting elements Ra11, Rb11, . . . arranged on intersecting areas of the scan lines and the data lines. Cathode terminals of the light emitting elements whose anode terminals are connected respectively to the two adjacent data lines A1, A2 are connected to different scan lines one by one. Any two of the scan lines are selected for scanning simultaneously. Thus, since light emission duty of each EL element can also be approximately doubled, instantaneous light emission intensity of each EL element can be set low, and stress on the EL elements can be reduced. Further, since respective data lines can be drawn from one side end portion of the display panel, dual scan drive becomes substantially possible by one data driver.

Implementation of discrete wavelet transform using lifting steps
InactiveUS7480416B2Low efficiencyControl speedColor television with pulse code modulationColor television with bandwidth reductionHardware architectureComputer architecture
Compact and efficient hardware architectures for implementing lifting-based DWTs, including 1-D and 2-D versions of recursive and dual scan architectures. The 1-D recursive architecture exploits interdependencies among the wavelet coefficients by interleaving, on alternate clock cycles using the same datapath hardware, the calculation of higher order coefficients along with that of the first-stage coefficients. The resulting hardware utilization exceeds 90% in the typical case of a 5-stage 1-D DWT operating on 1024 samples. The 1-D dual scan architecture achieves 100% datapath hardware utilization by processing two independent data streams together using shared functional blocks. The 2-D recursive architecture is roughly 25% faster than conventional implementations, and it requires a buffer that stores only a few rows of the data array instead of a fixed fraction (typically 25% or more) of the entire array. The 2-D dual scan architecture processes the column and row transforms simultaneously, and the memory buffer size is comparable to existing architectures. The recursive and dual scan architectures can be readily extended to the N-D case.

Self light emission display device
The present invention provides a self-luminous display device capable of substantially double-scanning driving by one data driver, wherein: a plurality of scanning lines ( K1 , K2 . . . ) A plurality of data lines (A1, A2...), and a plurality of light-emitting elements (Ra11, Rb11...) arranged in intersection regions of the scan lines and data lines. The anode terminals thereof are respectively connected to the cathode terminals of the light-emitting elements of the two adjacent data lines A1 and A2, and are sequentially connected to different scanning lines. Moreover, any two of the scanning lines are scanned and selected at the same time. Accordingly, the light emission operation time of each EL element can be approximately doubled, so that the instantaneous light emission luminance of each EL element can be set to a low value, and the workload on the EL element can be reduced. In addition, since each data line can be drawn out at one end of the display panel, it is possible to substantially perform double-scanning driving with one data driver.
