Abstract: A signal processor and an OLED display including the same are disclosed. In one aspect, the display includes a plurality of pixels and a luminance deterioration calculator configured to receive input image data and calculate luminance deterioration values of the pixels. A data compensator is configured to calculate compensation coefficients for each of the pixels based at least in part on the luminance deterioration values, adjust a compensation margin based at least in part on the maximum value of the compensation coefficients, and generate compensation image data for each of the pixels based at least in part on the compensation coefficients and the compensation margin. A panel driver is configured to generate data signals based at least in part on the compensation image data and transmit the data signal to the pixels and a timing controller configured to control the panel driver.

Abstract: A data compensator includes first logic, second logic, third logic, fourth logic, and fifth logic. The first logic calculates block compensation coefficients for blocks in a first frame based on first pixel data of the first frame. The second logic generates first gamma applied pixel data based on the first pixel data of the first frame and to generate second gamma applied pixel data based on the first gamma applied pixel data and second pixel data of a second frame adjacent the first frame. The third logic selects a number of the block compensation coefficients based on a pixel coordinate. The fourth logic generates a pixel compensation coefficient corresponding to the second pixel data by interpolating the selected block compensation coefficients based on the pixel coordinate. The fifth logic generates output pixel data based on the second gamma applied pixel data and the pixel compensation coefficient.

Abstract: The present invention provides a coolant demineralizer for a fuel cell vehicle, which removes ions, released from a pipe, from coolant of a fuel cell stack. In preferred embodiments, the present invention provides a coolant demineralizer suitably configured to reduce the occurrence of differential pressure due to an ion resin layer such that coolant can smoothly flow through a filter member, thereby increasing the effect of filtering ions and improving the efficiency of use of ion resin.

Abstract: An apparatus for injecting a coolant for a fuel cell vehicle is provided. More specifically, a coolant tank stores a coolant and a coolant pump, disposed in a coolant supply line connecting the coolant tank and the stack cooling loop is configured to pressure-transfer the coolant to the stack cooling loop, and circulating the coolant, which has passed through the stack cooling loop, to the coolant tank. A bubble elimination unit, disposed at a rear stage of the coolant pump in the coolant supply line, eliminates the bubbles in the fuel cell stack through vibration. This bubble elimination unit may be configured as an ultrasonic wave excitor for exciting the stack cooling loop with ultrasonic waves.
