Zusammenfassung:An apparatus for displaying images and a driving method thereof are provided to control charge density supplied to pixels by using a PWM(Pulse Width Modulation) scheme and a PAM(Pulse Amplitude Modulation) scheme. An apparatus for displaying images includes a rear plate(20), a face plate(21), and a driver. The rear plate includes plural electron emission devices for emitting an electron. The face plate, which is formed opposite to the electron emission devices, includes plural phosphors for generating beam according to irradiation of the electron. The driver scans the electron emission devices whose maximum charge density, which is radiated to one pixel phosphor during one scan period, is greater than 3x10^-8C/cm^2.
