Abstract

Описан модуль задней подсветки. Модуль задней подсветки содержит светопроводящую пластину, источник освещения, заднюю пластину и позиционирующий компонент для поддержания расстояния светового контакта между светоизлучающей поверхностью источника освещения и поверхностью светопроводящей пластины, на которую падает освещение. Существует расстояние светового контакта между светоизлучающей поверхностью источника освещения и поверхностью светопроводящей пластины, на которую падает освещение. Когда происходит изменение температуры, позиционирующий компонент подвержен первой деформации, а светопроводящая пластина подвержена второй деформации. Расстояние светового контакта остается неизменным под воздействием первой деформации и второй деформации. В настоящем изобретении улучшена надежность позиционирования светопроводящей пластины.
