This paper proposes a 10-bit linear gamma digitalto-analog converter (DAC) of source driver ICs for large-sized active matrix flat panel displays (AMFPDs). The proposed DAC employs the voltage adder to reduce the area of source driver IC. The voltage adder not only reduces the size of 7-bit DAC to about half by adding the fixed one least significant bit (LSB) voltage but also quickly settles the output to the target voltage by its pre-charged output. To verify the performance of the proposed DAC, the simulation and layout are performed with a 55-inch full high-definition active matrix organic light emitting diodes (AMOLED) display. The simulation result of the proposed DAC shows INL of 0.98 LSB and DNL of 0.69 LSB. The proposed DAC uses only 57.3% of number of transistors compared to the conventional 10-bit DAC with a 3-bit embedded amplifier, which results in reducing the area of source driver IC for AMFPDs significantly. Keywords-AMOLED, digital-to-analog converter (DAC), large-sized AMFPD, small area DAC, source driver IC, voltage adder.

“…A linear segmented DAC divides the input digital code into three sub digital codes, and each of the divided code is used to select the corresponding reference voltage from the resistor string [4]. However, this DAC occupies a large area of R-string because various reference voltages are selected by only one R-string.…”

“…Recently, reflective type displays, which include E-ink [1], Cholesteric LCD [2], electro-wetting [3], E-chromic [4], and MEMS [5][6] displays, have attracted research interests since they have excellent power efficiency as well as sun-light readability. These virtues are essential for displays aiming for applications in e-readers and mobile devices.…”

In this study, we attempted a new manufacturing route for an interferometric modulator type MEMS display. Instead of conventional pattern forming process, we developed backexposure procedure combined with lift-off process to reduce the number of masks and alignment steps used. The pixel structure manufactured revealed that this new procedure is capable of producing the device with high accuracy and quality.
