Problems solved by technology

However, because the black matrix cannot 100% block the light, and the lead wires (eg: gate lead wires) have a high voltage and the distance between the lead wires (eg: grid lead wires) is small, so the lead wires (eg: grid lead wires) The liquid crystal molecules above the electrode lead) are easily affected by the voltage of the lead (eg: gate lead), resulting in a slight light leakage at the lead (eg: gate lead)

[0035] figure 1 is a partial cross-sectional schematic diagram of a display panel according to an embodiment of the present invention. figure 2 yes figure 1 A schematic top view of the first substrate of the display panel, wherein figure 1 for correspondence figure 2 at the section of I-I', and figure 2 The illustration of the color filter layer, the black matrix and the film layer thereon is omitted.

[0036] Please also refer to figure 1 as well as figure 2 , the display panel of this embodiment has a display area 110 and a non-display area 120 located around the display area 110 . That is to say, the non-display area 120 surrounds the display area 110 . The display panel includes a first substrate 102 , a second substrate 104 and a display medium 106 . In a preferred embodiment, the first substrate 102 and the second substrate 104 are assembled together through the sealant 130, and the display medium 106 is located between the first substrate 102 and the second ...

[0052] in the above figure 1 , image 3 as well as Figure 4 In the embodiment, the organic layer 122 is covered on the light-shielding pattern layer 124, but the present invention is not limited thereto. In other embodiments, the light-shielding pattern layer 124 may also cover the organic layer 122 . Please refer to Figure 5 , Figure 5 The embodiment of figure 1 Similar, the only difference is that the organic layer 122 is formed on the protective layer 114 , and the light-shielding pattern layer 124 is located on the organic layer 122 . In a preferred embodiment, the upper surface of the organic layer 122 is further covered with the protection layer 116 . In addition, in Figure 5 In an embodiment, the conductive pattern 156 is located between the light-shielding pattern layer 124 and the organic layer 122 (or the protection layer 116 ). Since the conductive pattern 156 can be formed together with the pixel electrode 152, the pixel electrode 152 is formed on the p...

[0057] Figure 8 is a partial cross-sectional schematic diagram of a display panel according to an embodiment of the present invention. Figure 8 The embodiment of Figure 5Similar, except that the organic layer 122 above the lead L is not only designed with a conductive pattern 156, and the conductive pattern 156 and the electrode layer 164 are electrically connected to a common voltage, but also includes a pseudo-spacer 170 disposed on the conductive pattern 156. . In particular, there is a gap (A) between the pseudo-spacer 170 and the transparent electrode layer 162 on the second substrate 104 . If the display medium 106 in the display area 110 has a thickness (G), then the relationship between the gap (A) and the thickness (G) is A≧1 / 2G. The design of the pseudo-spacer 170 can displace the display medium (eg liquid crystal molecules) 106 above the lead L without affecting the thickness (G) of the display medium 106 in the display area 110 of the display panel. In addit...

The display panel comprises a first substrate, a second substrate and a display medium positioned between the first substrate and the second substrate, wherein the first substrate is provided with a pixel array, a plurality of lead wires, an organic layer and a conductive pattern; the pixel array is positioned in the display area; the lead wires are positioned in the non-display area and are electrically connected with the pixel array; the organic layer covers the pixel array and the lead wires; the conductive pattern is positioned on the organic layer on the lead wires; moreover, the second substrate is provided with a transparent electrode layer which is positioned in the display area and the non-display area, and particularly, the transparent electrode layer and the conductive pattern are electrically connected to common voltage.

Description

technical field [0001] The present invention relates to a display panel, and in particular relates to a color filter array integrated on a pixel array substrate (color filter on array, COA) or a black matrix integrated on a pixel array substrate (black matrix on array, BOA) display panel. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanel Display, FPD) has been vigorously developed. Among them, the liquid crystal display is based on its low voltage operation, no radiation scattering, light weight and small size. Gradually replace the traditional cathode ray tube display and become the mainstream of display products in recent years. Generally speaking, a liquid crystal display panel in a liquid crystal display is composed of a pixel array substrate, a color filter array substrate and a liquid crystal layer sandwiched between the two substrates. [0003] I...
