Problems solved by technology

[0003] In today’s widely used panel design, in order to prevent poor display such as light leakage, a blocking structure (BM, black matrix) is used for processing, so that about 30% to 70% of the backlight is blocked to varying degrees, making The displayed image cannot achieve the expected display effect, and it is difficult to adjust the contrast of the display panel to improve the display effect

Abstract

The invention discloses a display panel and a display device. The display panel comprises a first substrate, at least one reflection structure, a signal line and a control circuit, wherein at least one reflection structure is arranged on the first substrate and comprises a reflection layer and an electrochromic layer arranged on the reflection layer; the signal line is arranged on the first substrate; at least one part of the projection of at least one reflection structure on the first substrate along a direction vertical to the first substrate and at least one part of the projection of the signal line on the first substrate along a direction vertical to the first substrate are overlapped; the control circuit is arranged on the first substrate; and the control circuit is connected with theelectrochromic layer. By use of the display panel, the use ratio of a backlight light source is improved, and a display effect is improved.

Description

technical field [0001] The disclosure relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Currently, liquid crystal display panels have been widely used in electronic products of various sizes. Users also have a higher pursuit of the display effect of display products. Contrast is an important display parameter of LCD panels, which represents the difference between the brightest and darkest states of the panel. The larger the difference range, the greater the contrast, and the smaller the difference range, the smaller the contrast. A high contrast can make the display effect of the panel more rich, vivid and eye-catching, so in the optical design of the panel, it is particularly important to adjust the contrast. [0003] In today’s widely used panel design, in order to prevent poor display such as light leakage, a blocking structure (BM, black matrix) is used for processing, so that about 30%...
