The display device according to the present invention comprises: a printed circuit board on which a plurality of LEDs are mounted; a frame comprising a front surface for supporting the printed circuit board; and a cover member which covers the rear surface of the frame and comprises a plurality of outlets, wherein the frame comprises a first area extending from the front surface towards the rear surface, and a second area having pores and formed between the first area and the rear surface, and is provided to convect heat generated in the printed circuit board to the outlets via the first area and the pores.

An inexpensive system for maintaining an LCD display above an operative temperature includes ultraviolet (UV) light-emitting diodes (LEDs) incorporated into a backlight structure. The UV LEDs operate in a frequency range sufficiently removed from the visible band to not interfere with the user. A temperature sensor continuously or periodically monitors the temperature of the LCD and activates the UV LEDs to maintain the LCD in a predetermined temperature range for a desired response time.

Embodiments of the invention are related to modular display panels. In one embodiment, a modular display panel includes a first side which includes a display surface, and an opposite second side. The modular display panel further includes a plastic enclosure including an outer surface that forms substantially all of the second side. The modular display panel further includes LEDs arranged as pixels attached to a printed circuit board which is attached to the plastic enclosure. The modular display panel further includes a circuit for controlling the LEDs and a power source for powering the LEDs. The front side of the printed circuit board is sealed to be waterproof and the plastic enclosure is sealed to be waterproof so that the modular display panel is sealed to be waterproof.

A display device includes: a display panel; a driver IC that outputs a driving signal to the display panel; a flexible substrate on which the driver IC is mounted; a first frame that supports the display panel from a side of a light source; and a second frame that supports the light source while being provided independently of the first frame. The first frame includes a metallic frame unit which is opposite to the driver IC from the side of the light source.

A display device according to the present disclosure includes a second member (220) that is attachable to a first member (210) including a high-temperature part. The second member includes a first heat-transfer member (230) that is deformable and partially contactable with the high-temperature part and an elastic body (240) that allows the first heat-transfer member to abut on the high-temperature part.

In a display device, a flow path for an airstream that flows from a lower air vent toward an upper air vent along a circuit substrate, based on generated heat from a circuit component is defined so as to face a back surface of a display panel in a housing. The flow path is defined such that a sectional area of the flow path varies along the circuit substrate.

The present disclosure provides a display apparatus. The display apparatus includes a display module including a display panel and a guide plate, a flexible printed circuit board extending from the display panel, a source printed circuit board connected to the flexible printed circuit board and attached to the guide plate, at least one driving chip disposed on the source printed circuit board, and a protective member disposed to cover the flexible printed circuit board, the source printed circuit board, and the driving chip.
