Embodiment 1

[0049] refer to Figure 1 to Figure 3 , an embodiment of the present invention provides a display panel, which includes:

[0050] The first sub-panel 1 includes an opposing first substrate 81, a second substrate 82, and a first medium 18 and a first spacer wall 11 disposed between the first substrate 81 and the second substrate 82; the first The sub-panel 1 has a plurality of filter pixels 19 arranged at intervals, and the filter pixels 19 are used to generate a driving electric field in the first medium 18 to control its own light transmittance; the first spacer wall 11 is black, along the filter pixels The interval distribution of 19, and the dielectric coefficient is greater than the dielectric coefficient of the first medium 18;

[0051] Set on the light-emitting side of the first sub-panel 1 ( figure 1 , figure 2 The second sub-panel 2 with the upper side as an example) includes the opposite third substrate 83, the fourth substrate 84, and the second medium 28 and the...

Embodiment 2

[0100] An embodiment of the present invention provides a method for manufacturing the above-mentioned display panel, which includes the steps of forming each structure in the above two sub-panels.

[0101] For example, a preparation method of the above-mentioned display panel may specifically include:

[0102] S2001 , forming a gate electrode (GATE) and a first gate line on the first substrate through a patterning process.

[0103] S2002, forming a gate insulating layer (GI) on the first substrate.

[0104] S2003 , forming an active layer (ACT) on the first substrate through a patterning process.

[0105] S2004 , forming an interlayer insulating layer on the first substrate through a patterning process.

[0106] S2005, through a patterning process, a source electrode, a drain electrode, and a first data line (DATA) are formed on the first substrate.

[0107] S2006 , forming a passivation layer (PVX) on the first substrate through a patterning process.

[0108] S2007 , form...

Embodiment 3

[0140] An embodiment of the present invention provides a display device, which includes:

[0141] The above display panel:

[0142] A backlight located on the light-incident side of the display panel.

[0143] Specifically, the display device can be any product or component with display function, such as electronic paper, mobile phone, tablet computer, television, monitor, notebook computer, digital photo frame, navigator, etc.

Abstract

The present invention provides a display panel and a display device, belonging to the technical field of display, which can at least partially solve the problem of unsatisfactory display effect of the existing dual-box display panel. The display panel of the embodiment of the present invention includes: a first sub-panel, which includes a first medium and a first spacer wall disposed between the first substrate and the second substrate; the first sub-panel has a plurality of filters arranged at intervals pixel; the first spacer wall is black, distributed along the interval of the filter pixels, and the dielectric coefficient is greater than that of the first medium; the second sub-panel arranged on the light-emitting side of the first sub-panel includes a The second medium and the second spacer wall between the third substrate and the fourth substrate, the second sub-panel has a plurality of display pixels arranged at intervals; the second spacer wall is black, distributed along the interval of the display pixels, and The dielectric coefficient is greater than that of the second medium; the second substrate is located on the light-emitting side of the first sub-panel, and the third substrate is located on the light-incident side of the second sub-panel.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device. Background technique [0002] In order to improve the contrast ratio of the LCD panel, two LCD panels can be stacked together to form a dual-cell display panel, one of which is used to preliminarily filter the light from the backlight, and the other is used to The light undergoes final filtering to achieve display. [0003] Since the light is filtered twice, the contrast ratio of the dual-box display panel is very high, comparable to that of an organic light-emitting diode display panel (OLED), which can reach more than 150,000. However, the display effect of the dual-box display panel is still not ideal. SUMMARY OF THE INVENTION [0004] The present invention at least partially solves the problem of unsatisfactory display effect of the existing dual-box display panel, and provides a display panel and a display device which c...
