A New Pixel Circuit for Driving Organic Light-Emitting Diode With Low Temperature Polycrystalline Silicon Thin-Film Transistors

Morphology Optimization for the Fabrication of High Mobility Thin‐Film Transistors

“…[9][10][11] Currently, the low mobility of OTFTs is the main challenge for the industrial application of organic devices. [12][13][14] The fi ndings from a large number of researchers so far suggest that the charge carrier transport of OTFTs is extremely dependent on the semiconductor morphology, especially the fi rst several molecular layers near the dielectric surface.…”

Effect of single grain boundary position on surrounding-gate polysilicon thin film transistors

“…With the same threshold voltage of SG polysilicon TFT, V th variation can be reduced to less than within 5 %, with varying gate structures of GAA polysilicon TFTs. We demonstrate the 2T1C active-matrix driving circuit using GAA and SG polysilicon TFTs for OLED device [10]; and the results are fairly encouraging. The circuit with GAA polysilicon TFTs exhibits a nine times improvement in switching speed, compared to that with the SG polysilicon TFTs, 3-times increase in driving current, and 2-times higher stability of output driving voltage.…”

“…5. The characteristics of OLED are taken from the measured data [10,15]. Clearly, the left inset shows that the delay time of GAA circuit is about 0.12 s which is only one ninth of SG circuit.…”

Enhancement of Brightness Uniformity by a New Voltage-Modulated Pixel Design for AMOLED Displays

“…The use of AMOLED displays for large-size applications is expected to have many advantages, so the driving method and pixel structure should be applicable to large-size panels. However, most compensating pixel circuits with simple structures only solve one of the aforementioned problems [7], [8]. Some complicated designs have very uniform output current among pixels, but these may reduce the aperture ratio or require additional peripheral driving circuits [9], [10].…”
