Problems solved by technology

However, if Figure 11 As shown, heat transfer occurs at the contact portion (point A) between the display board and the supporting member, and the display board is rapidly cooled at the contact portion, but the cooling rate decreases at other parts (points B and C).
In this way, a temperature difference occurs between the cooling characteristic curves of the two parts, which causes display unevenness in the same way as when a load difference occurs.

Embodiment Construction

[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0034] In the description below, the "before and after" is referred to as figure 1 as a benchmark, figure 1 to the left of the front, with figure 1 The opposite side to the left side is the back. The "left and right" mentioned above refer to the left and right sides respectively when viewed from the rear.

[0035] refer to Figure 1 ~ Figure 3 , The cooling device is equipped with a cooling chamber 11 and a multi-layer support 12. The multi-layer frame 12 is arranged in the cooling chamber 11, and horizontally supports the flat display panel W such as a liquid crystal panel in multiple layers.

[0036] The cooling chamber 11 is substantially box-shaped and is composed of a rear side wall 21 , a front side wall 22 , a left side wall 23 , a right side wall 24 , a top wall 25 , and a bottom wall 26 .

[0037] An inlet 31 is provided on the rear side wall 21 , and a...

Abstract

The purpose of the invention supplies a cooling display plate device on the supporting condition without burden difference and temperature difference. The device comprises cooling room (11) and supporting device (12) inside the cooling room that can support the display plate (W) with multiple layers; supporting device (12) has supporting part (62), which is on horizon swinging axis (61) and has arc bearing surface (65) centered on the axes of swinging axis (61). By swing of swinging axis (61), as lapse of time, bearing surface (65) will touch different parts of the display plate (W).

Description

technical field [0001] The present invention relates to a cooling device for cooling, for example, a liquid crystal panel or a plate-shaped object for flat panel display (hereinafter collectively referred to as a display panel) heated for bonding a liquid crystal substrate to normal temperature. Background technique [0002] The heat treatment device is composed of a heating device for heating the display plate and a cooling device for cooling the heat-treated display plate. In the heating device and the cooling device, a support frame for supporting a display board is used. [0003] In order not to leave scratches on the display board, it is known to minimize the contact area of ​​the support frame with the display board and support multiple parts of the display board with pins or the like (for example, see Patent Document 1). [0004] However, when such a support method is adopted, the load of the display board concentrates on the pins and the like to cause a load differe...
