Display device and temperature sensing control module thereof

Abstract

The invention discloses a display device and a temperature sensing control module thereof. The temperature sensing control module comprises a temperature control voltage divider and a converter. The temperature control voltage divider includes a current limiting component and a temperature sensing component. The current limiting component and the temperature sensing component are connected in series between a high voltage end and a low voltage end to form a series connection point. The converter has a plurality of comparators; each of the plurality of comparators includes a first input terminal, a second input end, and an output end; the first input end is coupled to the series connection point; and the second input ends of the plurality of comparators receive a plurality of different reference values, wherein the plurality of reference value are greater than zero; and the plurality of comparators carry out comparison with the plurality of reference values based on a voltage dividing value from the series connection point to output a comparison result at the output end.

Description

technical field [0001] The invention relates to a temperature-sensing control module, in particular to a temperature-sensing control module and a display which are applied to the temperature-sensing control requirements of electric appliances. Background technique [0002] For a large-sized display, take a TV as an example, because the larger the size of the TV, the higher the resolution, and the higher the refresh rate, the operating current required by the TV is getting larger and larger. Moreover, since the integrated circuits (ICs) used in current TV driving circuits all have a certain working temperature limit, for example, the temperature limit required by the pulse width modulation integrated circuit (PWM IC) is 150°C. [0003] In the current panel driver design, the limited temperature range that can be used has basically reached the limit, for example: the maximum operating temperature marked in the specification is only 45°C. This will cause the TV's working tempe...

Problems solved by technology

This will cause the TV's working temperature to be limited, especially in environments with poor ventilation, poor heat dissipation, or outdoor exposure, it is easy to trigger the One Time Programmable (OTP) temperature protection mechanism, causing the TV Suspended and cannot view

In the past, although some TV temperature control technologies tried to solve the above problems, they still need to be improved.
