Embodiment Construction

[0030] The basic idea of ​​the present invention is: in the assembly method of the display device, the exposed conductive glue on the FPC gold finger is cured to form a protective film, which can prevent the gold finger from breaking and ensure sufficient connection between the FPC and the display panel.

[0031] Wherein, the conductive adhesive may be anisotropic conductive adhesive film (ACF).

[0032] FPC structure of the present invention such as Figure 4 As shown, the FPC includes a base material 21, a gold finger 22 and a conductive glue 23, wherein the upper surface of the gold finger 22 is provided with the base material 21, a part of the lower surface is provided with the base material 21, and the other part is the gold finger Conductive glue 23 is coated on the part exposed in the air. In this way, after the FPC is bound to the LCD screen, no gold finger will be exposed in the air.

[0033] In particular, the conductive adhesive 23 may be ACF with anisotropic cond...

Abstract

The invention discloses a method for assembling a display device. The display device comprises a flexible circuit board and a display panel, wherein the flexible circuit board comprises a bonding finger. The method includes the steps of enabling the flexible circuit board and the display panel to be arranged oppositely, pressing the flexible circuit board to enable the flexible circuit board to be bound with the display panel, and curing the exposed portion of conductive adhesive on the lower surface of the bonding finger to form a protective film. The method can effectively prevent the bonding finger from being prone to breakage due to the fact that the bonding finger is exposed in the air, further prevent pictures from displayed abnormally due to the fact that the bonding finger fails to fully transmit electric signals of a drive chip to the display panel, and improve yield of the display device.

Description

technical field [0001] The present invention relates to display technology, in particular to an assembly method of a display device. Background technique [0002] Existing FPC structures such as figure 1 As shown, it is mainly composed of a base material 21 and a gold finger 22, the gold finger 22 is used to transmit electrical signals, and the base material 21 is mainly used to protect the gold finger. Specifically, the upper surface and part of the lower surface of the gold finger 22 are covered with the base material 21, and the part 221 of the gold finger exposed in the air, that is, the lower surface of the part not covered with the base material 21 is used for bonding. ) display panel, the binding structure between FPC and display panel is as follows figure 2 shown. In current display devices such as (thin film transistor liquid crystal display (TFT-LCD) or organic light emitting diode (OLED) display), FPC mainly plays the role of connecting the display panel and t...
