[0051] A liquid crystal display that prevents short-circuiting of conductive gold balls

[0052] The liquid crystal empty box 6 is formed by spraying gaskets on the transfer point 2 made of the upper ITO glass substrate 1 and the sealant frame 4 made of the lower ITO glass substrate 3 respectively, aligning and laminating them, and then hot pressing and curing. The transfer point 2 is set in a small part of the frame area where the row and column electrodes of the upper and lower ITO glass substrates need to be transferred and conducted, that is, the row electrodes are led out, and is made of a transfer sealant dispersed with conductive gold balls 5 by screen printing , the sealant frame 4 is arranged in most frame ranges where the row electrodes do not need to be drawn out, and is made of screen-printed sealant.

[0053] The design width of the transfer point 2 is 0.27mm, and the design width of the sealant frame 4 is 0.30mm, which matches the design width of the transfer poi...

specific Embodiment approach 2

[0056] Another liquid crystal display that prevents conductive gold balls from shorting

[0057] The design width of the transfer point 2 is 0.27 mm, and the design width of the sealant frame 4 is 0.30 mm, which matches the design width of the transfer point 2 to ensure that the overlapping part 7 of the transfer point 2 and the sealant frame 4 is hot-pressed and expanded. The width is equal, and the shape of the joint part 8 between the transfer point 2 and the sealant frame 4 is a complementary shape that ensures that the overlapping part 7 of the transfer point 2 and the sealant frame 4 will not be glued and not enlarged after thermal expansion. The shape is For the combined shape of trapezoid and square, the overlapping portion 7 has a maximum width of about 0.25mm.

[0058] The manufacturing method of the present invention is used to screen-print the frame, the operating temperature is 23° C., the relative humidity is 65%, the screen printing pressure is 0.2-0.3 MPa, and ...

Abstract

The invention discloses a LCD for preventing the short circuit of conductive metal balls, and the making method thereof. A liquid crystal empty box is made by aligning and binding transferring points made on upper and lower ITO glass substrates with sealing glue frame after sprayed with liners, then heat-pressing and curing, where the transferring points are arranged in a small frame range needing to lead out row electrodes and made of transferring sealing glue scattered with conductive metal balls by silk-screen. The invention can obviously raise finished product yield.

Description

technical field [0001] The present invention relates to a method of manufacturing a device or device based on liquid crystals for controlling the intensity, color, phase, polarization or direction of light from an independent light source, and it relates to a liquid crystal display that prevents short-circuiting of conductive gold balls and its manufacturing method. Background technique [0002] Liquid crystal display LCD is equipped with upper and lower indium oxide and tin oxide composite film ITO glass substrates, and also includes color filters, polarizers, and alignment films. Row electrodes and column electrodes are arranged on the ITO glass substrates. With orientation material attached, the space between ITO glass substrates is generally less than 5×10 -6 The gap between them is filled with liquid crystal material, and the upper and lower ITO glass substrates are sealed with sealant to form a liquid crystal empty box. Most of the existing liquid crystal displays ado...
