Abstract
A chip press device and a chip press method are disclosed. The chip press device includes a base, a hot pressing head and a buffer, and a bearing surface of the base is a convex surface. The bearing surface of the base being a convex surface allows a display panel to deform slightly downwards during the chip pressing process. When the chip press is finished, the display panel deforms upwards under the shrinkage of the chip. Since the upwards deformation amount counteracts the downwards deformation amount, the warpage of display panel in conventional chip pressing process can be eliminated, which further avoids uneven uneven chromatic aberration in displayed images and improves the product quality.
