摘要： A resistive element (115) is connected in series to a cathode terminal of an LED light source at a last stage (or an anode terminal of an LED light source at a first stage) of an LED chain (116), and the resistive element (115) is configured to be variable in resistance value in accordance with a variation of voltage drops of the LEDs connected in series so that a resistive element connected to an LED chain having a large voltage drop has a small resistance value while a resistive element connected to an LED chain having a small voltage drop has a large resistance value. With this configuration, the power, which has been wasted otherwise as heat in the backlight driver IC, may be dispersed to the resistive elements.

摘要： A display device includes an LUT storing circuit and an LUT holding circuit, a representative point selecting circuit, and a compensation amount calculating circuit. The storing and holding circuits store and hold not compensation amounts of all points but compensation amounts of representative points in a lookup table. The representative point selecting circuit refers to a compensation amount for a representative point in the lookup table and three representative points neighboring an interpolating object point for deriving a compensation amount of each interpolating object point except the representative points in the lookup table. The compensation amount calculating circuit calculates the compensation amount of each interpolating point except the representative points by performing an interpolating operation with respect to the compensation amounts of the three neighboring representative points.

摘要： A hold-type display device reduces the blur of a moving image and makes less conspicuous the color shift caused due to different blur positions among RGB. In the case where the relative brightness of the video data of one or two of the three primary colors RGB changes from between 0 and 0.5 inclusive for the previous frame to between 0 and 0.5 inclusive for the present frame, the video image of the one or two colors is delayed by one frame and displayed.

摘要： A display device and system are disclosed, wherein the display system is so configured that an n-fold rate increasing circuit is arranged with a signal generating device instead of with the display device to realize a low-cost n-fold rate impulse-type drive. The n-fold rate display data is output to the display device from the signal generating device, and the display device includes a circuit to subject the input n-fold rate display data to the data conversion process for the n-fold rate impulse drive. In addition to the n-fold rate display data, an identification signal for identifying the position of the turn of the frames of the original video signal is input to the display device to prevent the erroneous data conversion operation.
