摘要： Embodiments described herein include a method for detecting a presence of an input in a capacitive sensing device that includes a sensing region and a plurality of sensor electrodes. The method includes driving a first column of transmitter sensor electrodes at a first potential and driving a second column of transmitter sensor electrodes at a second potential different than the first potential. The method includes acquiring a measurement from each row of sensor electrodes, where a first sensing node includes the first column of transmitter sensor electrodes and a third column of receiver sensor electrodes, and a second sensing node includes the second column of transmitter sensor electrodes and a fourth column of receiver sensor electrodes. The method also includes determining, using the measurements from each row of sensor electrodes, a first set of transcapacitive measurements corresponding to the plurality of sensor electrodes.

摘要： Embodiments include techniques that use color-shifting and luminance for creation and display of spatio-temporal dithered images. In one embodiment, adjacent pixels are color-shifted with respect to each other and the color values of the adjacent pixels are temporally alternated with color values of pixels in the group. In another embodiment, the luminance of group of adjacent pixels is determined and the luminance of the group is made more homogenous, spatially and temporally, by distributing color variations over a larger number of pixels so as to reduce the luminance difference between the pixel with the least luminance and the pixel with the greatest luminance. Individual color components (e.g., red, green, blue) may also be separated and used so that the color-shifts associated with each color component may be simultaneously present in different pixels.

摘要： An organic light emitting display apparatus includes a first data line, a comparator, and a data generator. The first data line is connected to a first pixel. The comparator compares first image data of input image data to at least one of a first critical grayscale value or a second critical grayscale value, where the first image data corresponds to the first pixel. The data generator determines the first critical grayscale value or the second critical grayscale value as first corrected image data when the first image data is equal to or greater than the first critical grayscale value but lower than the second critical grayscale value.

摘要： A driver for a display panel includes a driving time accumulator, a ditherer, and a data signal generator. The driving time accumulator determines an accumulated driving time of the display panel. The ditherer determines an amount of dither based at least in part on the accumulated driving time, and performs a dithering operation on input image data with the determined amount of dither. The data signal generator generates a data signal for the display panel based at least in part on the input image data on which the dithering operation is to be performed.

摘要： An apparatus of driving a liquid crystal display (LCD) includes a gray voltage generator generating a range of gray voltages that correspond to different LC light transmittance levels. These gray voltages, along with image data, are fed into a data driver. The data driver converts the gray voltages to a data voltage that properly generates the image indicated by the image data. The gray voltage values are chosen from a wider range of values than the pixel voltages, and this conversion may include determining a conversion factor based on the relative range sizes. This conversion may also include calculating the voltage difference between the previous data and the current data and adjusting the data voltage according to the magnitude of this difference. Generally, the larger the voltage difference, the larger is the data voltage magnitude that is needed to bring the pixel voltage to the target voltage within limited time.
摘要翻译：驱动液晶显示器（LCD）的装置包括产生对应于不同LC透光率水平的灰度电压范围的灰度电压发生器。这些灰色电压以及图像数据被馈送到数据驱动器。数据驱动器将灰度电压转换成正确生成由图像数据指示的图像的数据电压。灰度电压值从比像素电压的更宽范围的值中选择，并且该转换可以包括基于相对范围大小来确定转换因子。该转换还可以包括计算先前数据和当前数据之间的电压差，并根据该差异的大小调整数据电压。通常，电压差越大，在有限的时间内将像素电压带到目标电压所需的数据电压幅度就越大。

摘要： A circuit dithers pixel data on a display, and includes a lookup table module, a dithering parameter decoder, a first adder, a second adder, and an overflow handling module. A lookup table of the lookup table module stores dithering parameters generated by encoding odd and even pixel dithering parameters. The dithering parameter decoder generates second and third dithering parameters corresponding to odd and even pixels from a first dithering parameter. The first adder generates a dithered odd pixel parameter according to the odd pixel parameter and the second dithering parameter. The second adder generates a dithered even pixel parameter according to the even pixel parameter and the third dithering parameter. The overflow handling module checks for overflow, and generates an output odd pixel parameter according to the dithered odd pixel parameter, and generates an output even pixel parameter according to the dithered even pixel parameter.
