Embodiment approach 1

[0056] figure 1 It is a sectional view showing the liquid crystal television in Embodiment 1 and Embodiment 2 of the present invention. refer to figure 1 First, the basic structure of the LCD TV 100 in this embodiment will be described. The LCD TV 100 includes: a display assembly 10 that generates heat; a substrate 21 having a mounting surface 22 and configured at a distance from the display assembly 10; The component group 26; and the frame body 11 that accommodates the display module 10, the substrate 21, and the component group 26. The mounting surface 22 includes a main surface 22 a as a first surface extending opposite to the display module 10 , and a non-main surface 22 b as a second surface arranged behind the main surface 22 a. In the component group 26 , the tallest component 26A based on the mounting surface 22 is mounted on the main surface 22 a among the main surface 22 a and the non-main surface 22 b. Lower vent holes 18 as first vent holes located below the ...

Embodiment approach 2

[0084] Liquid crystal television 200 in Embodiment 2 of the present invention has substantially the same configuration as liquid crystal television 100 described in Embodiment 1. FIG. Hereinafter, descriptions of configurations that overlap with those of liquid crystal television 100 in Embodiment 1 will not be repeated.

[0085] refer to figure 1 First, the basic structure of the liquid crystal TV 200 in this embodiment will be described. The liquid crystal TV 200 includes: a display assembly 10 that generates heat; a main surface 22a having a first surface extending opposite to the display assembly 10; The non-main surface 22b of the second surface on the back side of the surface 22a, and the substrate 21 arranged at a distance from the display module 10; Components 26A, 26B, and component 26C as a second component group that generates heat; and housing 11 that accommodates display module 10 , substrate 21 , and components 26A, 26B, and 26C. The total heat generation of t...

Embodiment approach 3

[0093] Figure 9 It is a cross-sectional view showing a liquid crystal television in Embodiment 3 of the present invention. Liquid crystal television 300 in the present embodiment has basically the same configuration as liquid crystal television 100 in the first embodiment. The repeated structure will not be repeated below.

[0094] refer to Figure 9 Like the component group 26 in Embodiment 1, the components 81 to 85 (including the highest component among the component groups mounted on the substrate 21 ) are mounted on the main surface 22 a of the substrate 21 , and the component 86 is mounted on the non-main surface 22 b.

[0095] Liquid crystal television 300 in this embodiment further includes substrate 71 as another substrate provided separately from substrate 21 . The base plate 71 is disposed on a path of air flowing in from the lower vent hole 18 toward the space 32 .

[0096] The substrate 71 has a mounting surface 72 . The area of ​​the mounting surface 72 is ...

Abstract

A liquid crystal television set (100) is provided with a display module (10) which generates heat, a substrate (21) having a mounting surface (22), a component group (26) mounted on the mounting surface (22), a display module (10), the substrate (21) and a case (11) for storing the component group (26). The mounting surface (22) includes a main surface (22a) which extends by facing the display module (10), and a non main surface (22b) arranged on the rear side of the main surface (22a). A component (26A) having the largest height with the mounting surface (22) as reference, among the component group (26), is mounted on the main surface (22a) out of the main surface (22a) and the non main surface (22b).On the case (11), a lower ventilation port (18) is formed below the substrate (21), and an upper ventilation port (19) is formed above the substrate (21). In the case (11), an air flow passing through the lower ventilation port (18), a space (32) between the display module (10) and the main surface (22a), and the upper ventilation port (19) is formed. Thus, the display device has reduced thickness with improved cooling effects.

Description

technical field [0001] The present invention generally relates to thin display devices such as liquid crystal televisions, plasma display televisions, and liquid crystal displays, and more particularly to thin display devices having a heat dissipation structure for effectively dissipating heat emitted from a display panel unit and a control circuit unit. Background technique [0002] Regarding a conventional display device, for example, Japanese Patent Application Laid-Open No. 2003-173147 discloses a display device for the purpose of reliably suppressing temperature rise (Patent Document 1). The display device disclosed in Patent Document 1 includes a display panel that displays an image, a frame chassis that supports the display panel, and a circuit board that drives the display panel to display an image. A front surface design frame and a rear surface cover are fixed to the front and rear of the assembly composed of the display panel, the frame bottom plate, and the circu...
