Display device
View Patent ↗The present invention provides a display apparatus that can achieve high durability by making the most of the function of the exhaust fans to effectively suppress the rise of the temperature. The display apparatus comprises a display panel for displaying images, a rear case covering a rear side of the display panel, and an exhaust fan disposed within the rear case, wherein the rear case includes a first air-hole area and a second air-hole area each provided with a plurality of air holes, the first air-hole area is located at a higher level than the second air-hole area with respect to a vertical direction with a spacing therebetween, and at least partially faces the exhaust fan, and an area surrounded by the first air-hole area, the second air-hole area and external common tangents thereof is a shielded area in which no air hole is provided.
1. A display apparatus comprising
a display panel for displaying images;
a rear case covering a rear side of the display panel, the rear case including a first air-hole area, a second air-hole area, and a third air-hole area, each provided with a plurality of air holes, wherein the first air-hole area is located at a higher level than the second air-hole area with respect to a vertical direction with a spacing therebetween, and an area surrounded by the first air-hole area, the second air-hole area, and external common tangents between the first air air-hole area and the second air-hole area, is a shielded area in which no air hole is provided;
a drive circuit for driving the display panel disposed in an inner space surrounded by the display panel and the rear case, the drive circuit including a circuit substrate on which a plurality of electronic parts are mounted, wherein in the inner space, an electronic part that generates the largest amount of heat among the plurality of electronic parts is located in a space between the shielded area and the display panel;
an exhaust fan disposed within the rear case, wherein the first air-hole area at least partially faces the exhaust fan, and the third air-hole area is located a prescribed distance away from the exhaust fan; and
a partition disposed along the external common tangents.
2. The display apparatus of claim 1 , wherein
the inner space is separated by the partition.
3. A display apparatus comprising:
a display panel for displaying images;
a rear case covering a rear side of the display panel including a first air-hole area, a second air-hole area, and a third air-hole area, each provided with a plurality of air holes, wherein the first air-hole area is located at a higher level than the second air-hole area with respect to a vertical direction with a spacing therebetween, the third air-hole area is located at a lower level than the second air-hole area with respect to the vertical direction with a spacing therebetween, and an area surrounded by the first air-hole area, the second air-hole area, and external common tangents between the first air air-hole area and the second air-hole area is a shielded area in which no air hole is provided;
a drive circuit for driving the display panel is disposed in an inner space surrounded by the display panel and the rear case, the drive circuit including a circuit substrate on which a plurality of electronic parts are mounted, wherein in the inner space, an electronic part that generates the largest amount of heat amount the plurality of electronic parts is located in a space between the shielded area and the display panel;
a data driver IC disposed in the inner space so as to face the third air-hole area;
an exhaust fan disposed within the rear case, wherein the first air-hole area at least partially faces the exhaust fan, the third air-hole area is located a prescribed distance away from the exhaust fan; and
a partition disposed between the third air-hole area and the second air-hole area so that a flow of air in the vertical direction is obstructed, the partition having a size that fits a size of an area where the data driver IC is disposed.
