20120176351 | DOT INVERSION TFT ARRAY AND LCD PANEL - A dot inversion TFT array is provided. The dot inversion TFT array includes: a plurality of data lines; a plurality of dot unit pairs, each including a first dot unit and a second dot unit and coupled to one of the data lines; and a plurality of gate line pairs, each including a first gate line and a second gate line. A predetermined dot unit pair of the dot unit pairs is coupled to a predetermined gate line pair of the gate line pairs, and two horizontally neighboring dot unit pairs of the dot unit pairs are mirror-symmetrical. | 07-12-2012 |
20120299977 | Display Control Circuit and Method Thereof - A display control circuit is capable of adjusting backlight intensity according to image content as well as compensating pixel values of frames for power saving and distortion reduction. The display control circuit includes a threshold determining circuit, a pulse width modulation (PWM) control circuit and a pixel value adjusting circuit. The threshold determining circuit determines a threshold according to a reference value by histogramming a to-be-displayed frame. The threshold is smaller than an upper limit of the pixel values, and a proportion of the number of pixel values between the threshold and the upper limit which occupy a total pixel number is lower than the reference value. The PWM control circuit generates a PWM signal for controlling a backlight luminance according to the threshold. The pixel value adjusting circuit adjusts the values of the pixels according to the threshold. | 11-29-2012 |

20120185640 | CONTROLLER AND METHOD FOR CONTROLLING MEMORY AND MEMORY SYSTEM - A memory controller for multiple addressing modes is provided. The memory controller includes a transmitting unit and a control unit. The transmitting unit transmits an identification message to a non-volatile memory. According to whether the non-volatile memory feeds back an acknowledgement message in response to the identification message, the control unit determines an addressing mode to be used for communicating with the non-volatile memory. | 07-19-2012 |

20150062138 | TIMING CONTROLLER FOR IMAGE DISPLAY AND ASSOCIATED CONTROL METHOD - A timing controller for a panel display system includes: an image signal receiver that receives an image signal; an overdrive circuit that receives and converts the image signal from the image signal receiver according to successive first frame data and second frame data in the image signal; an image signal transmitter that receives the converted image signal from the overdrive circuit and transmits the same to a display panel; a memory; and a memory interface unit. In a normal read/write period, the memory interface unit receives the first frame data from the overdrive circuit and stores the same in the memory, and fetches the first frame data from the memory when the overdrive circuit receives the second frame data in the image signal and transmits the same to the overdrive circuit. The memory interface unit further obtains sampling results to generate a preferred delay phase. | 03-05-2015 |
