Problems solved by technology

However, the color filter pattern of the color filter is usually made of color photoresist material, and its absorption of light will lead to light loss, which in turn makes the light transmittance of the color filter poor.
When a color filter is attached above the black and white electrophoretic display layer of the reflective electrophoretic display device, the black and white electrophoretic display layer will be completely covered by the color filter, so that the overall light reflectance of the display device will be affected by the color filter. The light transmittance of the light sheet is poor and low, resulting in poor display quality of the display device

Abstract

The invention discloses a color display device comprising a lower substrate, a driving array, a display layer, a color filtering substrate and a transparent substrate. The driving array is configured on the lower substrate. The display layer is configured on the driving array, and comprises a first area and a second area. The color filtering substrate is configured on the display layer and located in the first area. The transparent substrate is configured on the display layer and located in the second area. The color display device has higher luminous reflectance, which is beneficial for improving display quality of the display device.

Description

technical field [0001] The invention relates to a display device, and in particular to a color display device. Background technique [0002] Conventional electrophoretic display devices are usually configured with a black and white electrophoretic display layer, so they are black and white display devices. In order to make the electrophoretic display device more competitive in the market, color filters are used in the prior art to make the electrophoretic display device achieve the effect of colorization, so that the electrophoretic display device conforms to the current trend of pursuing colorization of flat-panel display devices. . [0003] A color filter is generally composed of a substrate and a color filter pattern disposed on the substrate. When in use, the color filter is attached to the entire black-and-white electrophoretic display layer, and the color filter patterns (such as red filter patterns, green filter patterns, and blue filter patterns) of the color filte...
