Problems solved by technology

[0004] However, external water vapor easily enters the gap through the external opening of the gap, causing corrosion and disconnection of the pins in the gap due to moisture, forming vertical or horizontal line defects
If the moisture contains salt, the pins in the gap are more likely to be corroded and disconnected due to the salt in the moisture
As a result, the liquid crystal display device is likely to cause display defects (such as horizontal or vertical line defects) due to corrosion or disconnection of the pins in the gap, which greatly reduces the operational performance of the liquid crystal display device.

Embodiment 1

[0031] Please also refer to Figure 1A ~ 1C , Figure 1A The drawing is a top view of a flat panel display device according to an embodiment of the present invention. Figure 1B shows Figure 1A A schematic diagram of the state when the flat panel display device omits the first substrate, Figure 1C drawn along Figure 1A The cross-sectional view of the flat-panel display viewed by the section line 1C-1C'. The flat panel display device 10 of this embodiment may be a liquid crystal display device or an organic light emitting diode (OLED) display device, and a liquid crystal display device is used as an example for illustration here, but the technology of this embodiment is not limited thereto. .

[0032] exist Figure 1A ~ 1C Among them, the flat panel display device 10 at least includes a first substrate 11 , a second substrate 12 , a first sealing material 13 , a second sealing material 14 and a third sealing material 15 . The second substrate 12 is arranged parallel to th...

Embodiment 2

[0041] Please also refer to Figure 2A-2B , Figure 2A A top view showing a flat panel display device according to Embodiment 2 of the present invention, Figure 2B draw Figure 2A A schematic diagram of the state of the flat-panel display device when the first substrate is omitted. The difference between the flat panel display device 20 of the present embodiment and the flat panel display device 10 of the first embodiment lies in the third sealing material 25 , and the same reference numerals are used for the rest of the same components, and the connection relationship and functions between them will not be repeated.

[0042] exist Figure 2A-2B Among them, the third sealing material 25 and the first sealing material 13 that at least seal the first end 19a and the second end 19b of the gap 19 can be integrally formed, for example, the materials of the first sealing material 13 and the third sealing material 25 All are silicone. In addition, the third sealing material 25 ...

Embodiment 3

[0044] Please also refer to Figure 3A-3B , Figure 3A A top view showing a flat panel display device according to Embodiment 3 of the present invention, Figure 3B is shown along the Figure 3A The cross-sectional view of the flat-panel display viewed by the section line 3B-3B'. The difference between the flat-panel display device 30 of the present embodiment and the flat-panel display device 10 of the first embodiment lies in the third sealing material 35 and the second sealing material 34, and the rest of the same constituent elements continue to use the reference numerals, and the relationship between them will not be repeated. connections and functions.

[0045] exist Figure 3A-3B Among them, the second sealing material 34 is disposed around the surface edge of the first substrate 11 , so that the third sealing material 35 that at least seals the first end 19 a and the second end 19 b of the gap 19 is a part of the second sealing material 34 . Wherein, the second se...

Abstract

The plane display device includes the first substrate, the second substrate, the first sealing material, the second sealing material and the third sealing material. The second substrate is set in parallel to the first substrate and includes display area, peripheral circuit area and pins extending from the display area to the peripheral circuit area and the edge of the second substrate. The first sealing material around the display area connects the first substrate and the second substrate; the second sealing material located in the peripheral circuit area outside the first sealing material seals the edge of the first substrate and defines one interval together with the first substrate, the second substrate and the first sealing material. The interval has one first end and one second end sealed with the third sealing material.

Description

technical field [0001] The present invention relates to a flat display device, in particular to a flat display device in which at least the external opening of the gap is sealed with a sealing material. Background technique [0002] With the rapid progress of liquid crystal display device manufacturing technology and its advantages of thinness, power saving, and no radiation, liquid crystal display devices are widely used in personal digital assistants (personal digital assistants, PDAs), notebook computers, In various electronic products such as digital cameras, digital video recorders, mobile phones, computer screens and LCD TVs. Coupled with the industry's active investment in research and development and the adoption of large-scale production equipment, the quality of liquid crystal display devices has been continuously improved, and the price has been continuously reduced, so that the application fields of liquid crystal display devices have rapidly expanded. [0003] ...
