Embodiment Construction

[0019] figure 1 The appearance of the plasma display device of the present invention is shown. The plasma display device 100 is planar, for example, has a screen 50 with a diagonal of 32 inches. The size of the screen 50 in the horizontal direction is 0.72 m, and the size in the vertical direction is 0.4 m. The decorative case 101 , which determines the planar size of the display device 100 , has an opening larger than the screen 50 , and the front surface of the display panel assembly 1 is exposed except for the peripheral portion.

[0020] figure 2 An outline of the configuration of the display panel assembly is shown. The display panel assembly 1 includes a plasma display panel 2 , a front sheet 3 directly attached to the front surface of the plasma display panel 2 , and a drive circuit board (not shown). The front sheet 3 is composed of a plurality of layers including an optical film having an optical filter function and an EMI shielding film having an electromagnetic...

Abstract

The invention provides a display panel assembly and a manufacturing method thereof, aiming at reducing the manufacturing cost of the display panel assembly. In the manufacture of a display panel assembly having a display panel, a functional film, and a driving circuit board, the driving circuit board is mounted on the display panel, and the lighting inspection of the display panel is performed using the driving circuit board, and the display panel is confirmed to be a good product through this inspection, and then Attach the functional film to the front surface of the display panel. When attaching, an adhesive layer with a thickness greater than or equal to 200 μm is sandwiched between the front surface of the display panel and the functional film.

Description

technical field [0001] The present invention relates to a display panel assembly and a manufacturing method thereof. In particular, it relates to an improvement of a plasma display module in which a functional thin film is directly attached to the front surface. The display panel assembly is the main part of a thin display device, consisting of a display panel, a functional film and a drive circuit substrate. The display device includes a display panel assembly and a housing for accommodating it. Background technique [0002] The display panel is a device called a flat panel display such as a plasma display panel, a liquid crystal panel, an organic electroluminescent display, a field emission display, or the like. [0003] In a display device that displays images on a display panel, a light-transmitting functional film is attached to the front surface of the display panel in order to improve the performance of the display device. The functional film has at least a functio...
