摘要： A display apparatus includes a display panel, a memory, a bit-data convertor, a switch, and a gate driver. The display panel includes pixels. Each pixel is connected to one of the data lines and one of the gate lines. The memory stores a plurality of image data corresponding to a frame period. The bit-data convertor determines a plurality of bit data. Each of the bit data corresponds to a degree of change between adjacent image data among the plurality of image data, obtains a sum of the bit data, and outputs the sum of the bit data as a total count bit data value. The switch outputs a first pulse control signal corresponding to the total count bit data value. The gate driver generates a gate signal based on the first pulse control signal, and to output the gate signal to one of the gate lines.

摘要： A LED driving circuit comprises a high bit driving circuit, a low bit driving circuit and a driving output terminal. The high bit driving circuit coupled to a high bit signal of the grayscale signal determines a first current continuously driven during a grayscale period according to the value of the high bit signal. The first current is invariant during the grayscale period. The low bit driving circuit coupled to a low bit signal of the grayscale signal determines a second current driven in at least two time intervals during the grayscale period according to the value of the low bit signal. The driving output terminal coupled to the high bit driving circuit and the low bit driving circuit outputs the driving current added by the first current and the second current. Accordingly, the LED display can be improved with higher refresh rate and/or better uniformity in low grayscale.

摘要： A display driver circuitry with permutation and superposition gray-level control comprises a gray-level controller. The controller may comprise a permutation and superposition adder configured to divide N-bit gray-level data G into M most significant bits, serving as a superposition reference GH, and (N−M) least significant bits, serving as a superposition increment GL, and to superpose superposition values Xi onto GH to derive pieces of scan data Gi for S scan operations; an overflow bit setting unit configured to set an overflow bit F; and an output unit configured to output the scan data Gi. A display driven this way has an improved refreshing frequency with the same gray-level reproduction ability as PWM-based schemes. Further, the duration of each scan operation, or scan period, is constant, resulting in convenience in software implementations. Furthermore, the pulse width representative of the gray-level value is determined by superposition of the scan operations.

摘要： Display irregularities in light emitting devices, which develop due to dispersions per pixel in the threshold value of TFTs for supplying electric current to light emitting elements, are obstacles to increasing the image quality of the light emitting devices. An electric potential in which the threshold voltage of a TFT (105) is either added to or subtracted from the electric potential of a reset signal line (110) is stored in capacitor means (108). A voltage, in which the corresponding threshold voltage is added to an image signal, is applied to a gate electrode of a TFT (106). TFTs within a pixel are disposed adjacently, and dispersion in the characteristics of the TFTs does not easily develop. The threshold value of the TFT (105) is thus cancelled, even if the threshold values of the TFTs (106) differ per pixel, and a predetermined drain current can be supplied to an EL element (109).
