Description

Technical Field

[0001] The utility model relates to a LTPS display panel, more specifically, to a LTPS display panel. Background Art

[0002] In the display panel industry, products must undergo a series of reliability tests before shipment, among which the water vapor test at high temperature is an essential test. This test can detect the product's ability to resist water vapor. If the product's sealing is not good, water vapor will enter the panel during the test and cause display abnormalities.

[0003] like Figure 7-8 As shown, the LTPS display panel includes an array glass substrate 1 and a CF glass substrate 2, and the CF glass substrate 2 is bonded to the array glass substrate 1 by a sealing frame glue 3. An insulating layer 11 is provided on the upper surface of the array glass substrate 1, and the edge of the insulating layer 11 is etched to form an annular groove 112. When bonding, the sealing frame glue 3 is filled in the annular groove 112. During the filling process of the sealing frame glue 3, the sealing frame glue 3 cannot always completely fill the annular groove 112, thereby generating a gap. When conducting a reliability test, water vapor will enter the panel from this gap, causing abnormal display of the panel. Utility Model Content

[0004] Based on this, it is necessary to provide a LTPS display panel to address the above technical issues.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A LTPS display panel, the LTPS display panel comprises an array glass substrate and a CF glass substrate, the CF glass substrate and the array glass substrate are bonded and connected by a sealing frame adhesive, an insulating layer is provided on the upper surface of the array glass substrate, and a plurality of discrete grooves are provided on the edge of the insulating layer; the sealing frame adhesive covers the grooves and the outer side of the edge of the insulating layer.

[0007] As a preferred embodiment of the present invention, the grooves are arranged at equal intervals along the circumference of the edge of the insulation layer.

[0008] As a preferred embodiment of the present invention, the insulating layer is SiNx.

[0009] As a preferred embodiment of the present utility model, the cross section of the groove is strip-shaped.

[0010] As a preferred embodiment of the present utility model, the cross section of the groove is circular.

[0011] The utility model provides an LTPS display panel, in which a plurality of discrete grooves are arranged at the edge of the insulating layer, that is, a discontinuous structure is adopted instead of a continuous structure. The discontinuous structure can realize that when the array substrate and the color film substrate are bonded together, the high point insulating layer around the groove area can generate an inward force around the groove area to act on the sealing frame glue, so that the sealing frame glue can be more evenly filled into the groove to avoid the generation of gaps, and the reliability of the bonding between the array glass substrate and the CF glass substrate layer can be effectively improved, and the water vapor has a better barrier effect, thereby improving the sealing and reliability of the panel.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] like Figures 1 to 6 As shown, the LTPS display panel includes an array glass substrate 1 and a CF glass substrate 2. The CF glass substrate 2 is bonded to the array glass substrate 1 by a sealing frame glue 3. An insulating layer 11 is provided on the upper surface of the array glass substrate 1. The edge of the insulating layer 11 is provided with a plurality of discrete grooves 111. The sealing frame glue 3 covers the grooves 111 and the outer side of the edge of the insulating layer 11.

[0024] The grooves 111 are arranged at equal intervals along the circumference of the edge of the insulation layer.

[0025] It should be noted that these grooves 111 are arranged at equal intervals.

[0026] In addition, the insulating layer 11 is SiNx.

[0027] In addition, the groove 111 is in a strip shape.

[0028] This embodiment is further described below.

[0029] A number of discrete grooves are provided at the edge of the insulating layer, that is, a discontinuous structure is adopted instead of a continuous structure. This discontinuous structure enables the insulating layer at high points around the groove area to generate inward forces acting on the sealing frame glue 3 when the array substrate and the color film substrate are bonded together, so that the sealing frame glue 3 is more evenly filled into the groove to avoid gaps. This can effectively improve the reliability of bonding between the array glass substrate and the CF glass substrate layer, has a better barrier effect on water vapor, and improves the sealing and reliability of the panel.

[0030] like Figure 4 As shown, these grooves 111 are circular.

[0031] Of course, the shape of the groove 111 is not limited to a strip or a circle, and may also be other shapes.

[0032] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
