ABSTRACT:
The present inventions provide a fusible seal for sealing liquid crystal display (LCD) devices. A fusible seal is formed on a transparent plate or on a die having a pixel array. The fusible seal is configured to encircle the pixel array of the die when the die and the transparent plate are joined. The die and the transparent plate are joined together such that the fusible seal is disposed between the transparent plate and the die. Heat is locally applied to the fusible seal without significantly heating the transparent plate or the die. Heating the fusible seal fuses the transparent plate to the die and encloses the pixel array. A LCD device is thereby formed without the need to cure the entire LCD device, which often times causes warping of the LCD device.
