Abstract
A plasma display panel driving method and a plasma display device estimate the highest temperature and the lowest temperature the panel can have, according to the temperature detected by the thermal sensor, and appropriately drives the panel, to improve the image display quality. Provided are at least three driving modes having different sub-field structures: a low-temperature driving mode, an ordinary-temperature driving mode, and a high-temperature driving mode. To drive the panel, estimates of the highest temperature and the lowest temperature the panel can have are made from the temperature detected by the thermal sensor, the temperature condition of the panel is determined from the estimated highest temperature or lowest temperature, and the driving mode is switched appropriately for the panel temperature condition.
