Abstract: A luminance correction system and method include: a data signal application module that applies a data signal to emit light at a maximum luminance; a luminance measurement module that measures luminance of a display region to which the data signal is applied; a comparator that compares luminance with a target value of luminance to obtain a difference value therebetween; a lookup table that adjusts luminance variations of R, G, and B pixels included in the display region by corresponding to the difference value; a data adjustment module that adjusts the data signal depending on the luminance variations of the R, G, and B pixels to transfer it to the data signal applying module; a color coordinate judgment module that judges a color coordinate of the display region; and a chroma correction module that controls chroma corresponding to the color coordinate judged by the color coordinate judgment module.

Abstract: A liquid crystal display device including a light source controller for controlling red, green, and blue lights to be sequentially transmitted through a liquid crystal and a pixel formed between a first substrate on which a first electrode is formed and a second substrate on which a second electrode is formed. A first red light emitting diode (LED) has a first terminal coupled to a first terminal of the light source controller; and a second red LED has a first terminal coupled to a second terminal of the first red LED. A green LED has a first terminal coupled to the first terminal of the light source controller; and a blue LED has a first terminal coupled to the first terminal of the light source controller.

Abstract: An organic light emitting display including: a pixel unit to display an image, according to a data signal and a scan signal; a data driver to supply the data signal, according to a video signal; and a scan driver to supply the scan signal. The data driver includes a memory to store a corrected offset voltage and to control a voltage of the data signal according to the corrected offset voltage.

Abstract: An organic light emitting display device and a driving method for the same is provided. The device includes a pixel portion adapted to receive a scan signal and a data signal and display an image. A scan driver generates and applies the scan signal to the pixel portion. A data driver generates and applies the data signal and a pixel voltage to the pixel portion. When the device is operating in the normal mode, the data driver also applies a drive voltage to a photo sensor also included in the display device. The photo sensor adjusts a luminance of the pixel portion according to a sensed brightness of ambient light. When the device is operating in the power saving or stand-by mode, the data driver controls the drive voltage off and thereby prevents power consumption by the photo sensor.

Abstract: A mobile terminal has an image corrector which includes a comparator for receiving a first image signal photographed by a camera in a camera mode and a second image signal displayed in a normal mode, and for comparing them with a reference signal to generate a deviation signal, and a corrector for receiving the deviation signal from the comparator, and for supplying the first or second image signal, in which white balancing and gamma are corrected, in response to the deviation signal so that luminance and white balance of the first image signal displayed in the camera mode become equal to or similar to luminance and white balance of the second image signal displayed in the normal mode.

Abstract: A driving method of a liquid crystal display (LCD) device including a light source controller controlling red, green, and blue lights to be sequentially transmitted through a pixel formed by a liquid crystal disposed between a first substrate and a second substrate. First grayscale data is applied to the pixel. Second grayscale data to be applied to the pixel is compensated by changing the second grayscale data to third grayscale data corresponding to the first grayscale data and the second gray scale data. Then the third grayscale data is applied to the pixel.
