However, when the outdoor ambient light brightness is reduced (for example, at night), the display brightness of the reflective display panel is also reduced, and the display effect is poor.

The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Likewise, the word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.

In one example, a transflective display panel is provided that may use a reflective mode in a high brightness environment and a transmissive mode in a low brightness environment. Compared with the conventional reflective display panel, the transflective display panel can achieve a better display effect even in a low-brightness environment, thereby improving the application range of the display panel. However, since the transflective display panel has a transmissive region as a region originally used for reflection, its reflectance is low, and the display effect in a high-luminance environment is affected.
