Description

Color filter substrate and display panel

The present disclosure relates to a display device and components thereof, and to a display panel and a color filter substrate thereof.

In recent years, electronic devices such as tablet PCs and smart phones have frequently appeared in daily life, and display panels applied to such electronic devices are, for example, organic light-emitting diodes ( The Organic Light Emitting Diode (OLED) display panel has been paid attention to because of its high color saturation and lightness, and can be used as a touch display panel with the touch function to increase the function and practicability of the electronic device. In addition, the touch display panel fabricated on the glass plate has been gradually replaced by a flexible substrate to improve the practicality of the electronic device configured with such a flexible touch display panel, wherein the aforementioned organic light emitting diode display panel is further used. Improvement into a soft touch display panel has attracted more attention.

However, in the fabrication of the flexible organic light-emitting diode touch display panel, in addition to the process problem of manufacturing the touch display panel with the flexible substrate, the packaging process of the organic light-emitting diode element is also difficult due to the flexible substrate. degree. For example In other words, the conventional touch display panel can block the penetration of air by the glass plate to prevent the moisture and oxygen in the air from damaging the organic light emitting diode element, but the resistance of the flexible substrate made of the transparent polymer material is blocked. The gas capacity does not meet the gas barrier requirements of the organic light-emitting diode component during the packaging process. At this time, the gas barrier member can be prevented from penetrating the flexible substrate to affect the organic light emitting diode element. The gas barrier component can be deposited directly on the organic light emitting diode component or deposited on another substrate and then bonded to the organic light emitting diode component. The former needs to consider the process compatibility of the gas barrier component and the organic light emitting diode component, while the latter needs to increase the lateral gas barrier component to enhance its gas barrier property. In addition, in order to improve color saturation, an organic light emitting diode display panel usually incorporates a color filter (CF). Therefore, how to integrate a color filter on a soft organic light emitting diode touch display panel and ensure process reliability and production yield is also an urgent problem to be solved in the technical field.
