Embodiment Construction

[0037] The invention provides a lamination method of a straight-pull display screen, the lamination method comprising the following steps:

[0038] Such as image 3 As shown, at least two first conductive blocks 12 are formed on the display panel 1, as Figure 4 As shown, at least two second conductive blocks 22 for alignment with at least two first conductive blocks 12 are formed on the IC (integrated circuit) panel 2, and at least two first conductive blocks 12 are used as the display panel 1 The alignment mark of the binding area 11, at least two second conductive blocks 22 are used as the alignment mark of the binding area 21 of the IC panel 2; there are a plurality of binding terminals 111 in the binding area 11, and there are A plurality of binding terminals 211 .

[0039] Such as Figure 5 As shown, conductive glue 3 is coated on the bonding area 11 of the display panel 1 , and insulating glue 4 is coated on at least two first conductive blocks 12 ; there is a gap be...

Abstract

The invention provides a straight pull display and a pressing method thereof. The method includes the steps that at least two first conductive blocks are formed on a display panel, and at least two second conductive blocks for aligning with that at least two first conductive blocks are formed on an IC panel; a conductive adhesive is coated on a binding area of the display panel and coating an insulating adhesive on at least two first conductive blocks; the IC panel is fixed above the display panel, so that the IC panel is parallel to the display panel, and the IC panel is moved along the parallel direction of the display panel so that at least two second conductive blocks and at least two first conductive blocks correspond one by one to form at least two capacitors respectively, and when the capacitance value of any one of the capacitors reaches the maximum, the IC panel is moved toward the display panel so that the IC panel and the display panel are stamped together. The invention canaccurately judge whether the binding area of the IC panel and the binding area of the display panel are aligned and pressed without passing an optical microscope.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a straight-pull display screen and a pressing method thereof. Background technique [0002] In 2017, with the release of full-screen mobile phones such as Samsung S8 / Note 8 and IPhone X, full-screen technology has become the current trend. The so-called full screen means that the front of the mobile phone is all used to display effective information. The surroundings of the mobile phone adopt a borderless design, pursuing a screen-to-body ratio close to 100%. Popular with mass consumers. However, due to problems in the existing panel design and manufacturing process, such as earpieces, front-facing cameras, fingerprint recognition, iris recognition, etc. will occupy part of the display area, so the current screen-to-body ratio of full-screen products is only about 90%. The existing full-screen technology implementation scheme generally uses COF (Chip On Flex or Chip On Film, a...
