TFT Arrays use active matrix addressing where each pixel has its own transistor switch, providing faster response, better contrast, and higher resolution compared to passive matrix displays that use simpler row/column addressing.
Dead pixels result from transistor failures, electrode defects, or contamination during manufacturing. Stuck pixels (always on/off) typically indicate transistor or capacitor malfunctions, while dark pixels often result from electrode breaks.
TFT Arrays with higher mobility materials like LTPS or IGZO require lower operating voltages, reducing power consumption. The aperture ratio (percentage of light-transmitting area) also significantly impacts backlight power requirements.
