Problems solved by technology

However, metal wiring (also known as metal wiring) is generally provided in the sealing area of ​​the array substrate, and the metal wiring can also block ultraviolet rays. Therefore, in practice, the metal wiring is made into a grid shape to improve light transmission. Ratio (that is, increasing the opening ratio of the metal traces), so that ultraviolet rays can irradiate the sealant; but this will undoubtedly reduce the conductivity of the metal traces, thereby affecting the response speed of the display device

Embodiment 1

[0032] An embodiment of the present invention provides a frame sealing glue composition, including: colloid and X-ray phosphor doped in the colloid; the X-ray phosphor can generate light after being irradiated with X-rays to make the colloid solidify.

[0033] Here, there is no limitation on the material of the X-ray phosphor and the specific light generated after X-ray irradiation, which can be selected according to the curing type of the colloid. For example, if the above-mentioned colloid can be cured after being irradiated with ultraviolet rays, then you can choose an X-ray phosphor that can generate ultraviolet rays after X-ray irradiation (which can be called X-ray ultraviolet phosphor); Curing can be achieved after irradiation, so X-ray phosphors that can generate visible light after X-ray irradiation can be selected. Of course, other types of X-ray phosphors can also be selected, which is not limited here.

[0034] In order to achieve a better curing effect, for examp...

Embodiment 2

[0039] An embodiment of the present invention provides a display panel to be cured, including: any one of the sealant compositions provided in Embodiment 1.

[0040] The above-mentioned display panel to be cured may also include: figure 1 As shown in the array substrate 10 and the color filter substrate 11 , the sealant composition 7 is located between the array substrate 10 and the color filter substrate 11 . It should be noted, figure 1 The color filter substrate is located above the array substrate. At this time, the X-rays emitted by the X-ray source enter from the side of the color filter substrate of the display panel to be cured; of course, the array substrate can also be located above the color filter substrate. At this time, the X-ray source The emitted X-rays enter from the array substrate side of the display panel to be cured. The embodiments of the present invention do not limit this, and only take the color filter substrate above the array substrate as an exampl...

Embodiment 3

[0045] An embodiment of the present invention provides a curing device for curing the sealant composition of the display panel to be cured provided in Embodiment 2. Refer to figure 1 As shown, the curing device includes:

[0046] X-ray source 1, X-ray source 1 is used to provide X-ray 2; X-ray mask plate 3, X-ray mask plate 3 comprises: light-transmitting portion 4 and light-shielding portion 5; X-ray mask plate is used for making X-ray The X-rays 2 emitted by the source 1 irradiate at least the sealant composition 7 of the display panel 6 to be cured through the light-transmitting portion 4 .

[0047]X-rays are electromagnetic waves with wavelengths between ultraviolet and gamma rays. Because of its short wavelength and high energy, when it shines on a substance, only part of it is absorbed by the substance, and most of it passes through the atomic gap, showing strong penetrating ability, and can penetrate ink paper, wood, metal, etc. Substances that are opaque to visible l...

Abstract

The invention provides a frame sealing adhesive composition, a to-be-cure display panel, a curing device and a display panel and relates to the technical field of display. When the frame sealing adhesive composition is cured, external ultraviolet irradiation can be avoided, and a curing effect is ensured. The frame sealing adhesive composition comprises an adhesive body and further comprises X-ray fluorescent powder doped in the adhesive body. The X-ray fluorescent powder can produce light so as to cure the adhesive body after being exposed to X-ray irradiation. The frame sealing adhesive composition is suitable for manufacturing of the to-be-cure display panel, the curing device and the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a frame sealing compound, a display panel to be cured, a curing device, and a display panel. Background technique [0002] LCD (Liquid Crystal Display, liquid crystal display) has been widely used in the field of display. LCD generally includes a color filter substrate and an array substrate (also known as an Array substrate) in a box, as well as a liquid crystal and a sealant between the array substrate and the color filter substrate. [0003] In the prior art, the frame sealant needs external ultraviolet (UV) irradiation to be cured (ie photocured). However, the sealant is generally arranged between the sealant area of ​​the color filter substrate and the sealant area of ​​the array substrate. In order to prevent light leakage, a black matrix (Black Matrix, BM) is provided in the sealant area of ​​the color film substrate; and the black matrix will block external ultraviolet...
