Abstract

The invention provides a display device and a source electrode driver thereof, wherein the source electrode driver comprises a temperature sensor and a power switch. The temperature sensor is used for measuring a first operation temperature of the source electrode driver, and generates an overtemperature protection starting signal through comparing the first operation temperature with a first preset temperature. The power switch is coupled in a power transmission path of a core circuit of the source electrode driver for receiving the operating power. The power switch switches on or off the power transmission power according to the overtemperature protection starting signal.

Description

technical field

[0001] The present invention relates to a source driver and its display device, and in particular to a source driver with temperature sensing capability and its display device. Background technique

[0002] In a traditional liquid crystal display (Liquid Crystal Display, LCD), it is often necessary to include multiple source drivers (Source Driver, SD) to generate corresponding driving signals with the gate driver to receive pixel data and output a driving voltage to on the driver display panel. However, when the source driver works for a long time, since it continuously provides alternately switching positive and negative driving voltages to the display panel, the source driver will generate heat to increase its operating temperature.

[0003] Based on the above situation, if the source driver of the LCD cannot monitor its own operating temperature and activate the protection function accordingly, the operating temperature of the LCD will continue to increa...
