Title:
GAMMA REFERENCE VOLTAGE GENERATING CIRCUIT AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/190429
Kind Code:
A1
Abstract:
Disclosed are a gamma reference voltage generating circuit and a display device, the gamma reference voltage generating circuit comprising a reference voltage generating unit and a plurality of resistance units (R1, R2,… Rn, Rn+1), the reference voltage generating unit being arranged on a printed circuit board, the plurality of resistance units (R1, R2,… Rn, Rn+1) receiving a reference voltage from the reference voltage generating unit and outputting a first gamma reference voltage, and the plurality of resistance units (R1, R2,… Rn, Rn+1) being formed on a region separate from the printed circuit board. Using the gamma reference voltage generating circuit and the resistance units (R1, R2,… Rn, Rn+1) formed on a region separate from the printed circuit board reduces the space occupied by the printed circuit board, and saves manufacturing costs.
