发明名称 DISPLAY DEVICE
摘要 A display device includes: a pixel region in which plural pixels, each including a light emitting element, a capacitor, a drive transistor, and a switch transistor, are arranged in rows and columns; scanning lines; signal lines; and parasitic capacitance which occurs between a source node of the light emitting element of each of the plural pixels and a signal line among the signal lines, wherein when images having different grayscales are displayed in the pixels on adjacent rows which are a 1st-row pixel and a 2nd-row pixel, a difference between a gate-source voltage of the drive transistor of the 1st-row pixel and a gate-source voltage of the drive transistor of the 2nd-row pixel is less than a voltage value of one grayscale, the difference being represented by ΔVdata×Cad/(Cs+Cad+Coled).

主权项 1. A display device comprising: a pixel region in which plural pixels, each including a light emitting element, a capacitor, a drive transistor, and a switch transistor, are arranged in rows and columns; scanning lines which supply the switch transistors with control signals for controlling an on-state and an off-state of the switch transistors; signal lines which supply the plural pixels with image signals for causing the light emitting elements to emit light having desired luminances; and parasitic capacitance which occurs between a source node of the light emitting element of each of the plural pixels and a signal line among the signal lines, wherein a 0th-row pixel, a 1st-row pixel, and a 2nd-row pixel included in the plural pixels are connected to the signal line and supplied with a first image signal, a second image signal different from the first image signal, and the second image signal, respectively, and a difference between a gate-source voltage of the drive transistor of the 1st-row pixel and a gate-source voltage of the drive transistor of the 2nd-row pixel is less than a voltage value of one grayscale, the difference being represented by: ΔVdata×Cad/(Cs+Cad+Coled) where ΔVdata denotes a difference between the first image signal supplied to the 0th-row pixel and the second image signal supplied to the 1st-row pixel, Cs denotes capacitance of the capacitor, Cad denotes the parasitic capacitance, and Coled denotes capacitance of the light emitting element.
