摘要:
A hybrid digital to analog converter (DAC) includes a first digital to analog converting unit (DACU) and a second DAC unit. The first DAC unit provides an analog voltage corresponding to Q-bit upper data of P-bit gray data, in response to a plurality of gamma voltages, where P is a natural number equal to or greater than 10 and Q is a natural number less than 10. The second DAC unit provides an analog current having a magnitude according to each bit level of R-bit lower data of the P-bit gray data, based on a rated current generated from a reference voltage, where R is a natural number corresponding to P-Q.
摘要:
A liquid crystal display (LCD) module includes a flexible backlight unit panel. The LCD module includes an LCD panel and the flexible back light unit panel. The flexible back light unit located behind of the LCD panel includes a plurality of planar light sources that are arranged in a matrix form to provide backlight to the LCD panel. The LCD module does not require diffusion sheet for distributing light sources, has a simple structure and is implemented as a small size, and may effectively perform a local dimming operation.
