Embodiment 1
[0031] as attached figure 2 As shown, it is a schematic structural diagram of a transflective liquid crystal display provided in this embodiment, and the liquid crystal display specifically includes:
[0032] The lower substrate 10, the upper substrate 20 and the liquid crystal layer 30 located therebetween;
[0033] The lower substrate 10 at least includes a first substrate 101, an organic film insulating layer 102 located on the side of the first substrate facing the liquid crystal layer 30, and a first reflective metal layer 1031 located on the organic film insulating layer 102; the organic film insulating layer 102 has a beveled edge 1021;
[0034] Wherein, the corresponding area of the first reflective metal layer 1031 is the reflective area R, and the remaining area is the transmissive area T. The first reflective metal layer 1031 is used to reflect the incident natural light from the outside to the liquid crystal display, so as to ensure the contrast of the liquid ...
Embodiment 2
[0043] In order to realize the separate control of the electrode potentials in the reflective area and the transmissive area in the transflective liquid crystal display, such as image 3 As shown in the partial structural schematic diagram of the liquid crystal display provided, the reflective area is R, the transmissive area is T, and the first black matrix 202. The lower substrate described in Embodiment 1 may also include: A first thin film transistor 401 (TFT, Thin Film Transistor) and a second thin film transistor 402 .
[0044] The first thin film transistor 401 is used to control the potential of the pixel electrode in the reflective region R, and the second thin film transistor 402 is used to control the potential of the pixel electrode in the transmissive region T.
[0045] In the pixel of the transflective liquid crystal display provided in this embodiment, the first gate line 501 and the first data line 601 connected to the first thin film transistor 401 are used to...
Embodiment 3
[0050] In the transflective liquid crystal display provided by the embodiment of the present invention, white light can also be converted into red, green, and blue primary color light beams by setting a color filter layer, and other components such as a liquid crystal layer and a polarizer can be used to display different color images. Effect.
[0051] Therefore, the difference between this embodiment and Embodiment 1 is that in the transflective liquid crystal display provided by this embodiment, the upper substrate may also include red, A color filter layer composed of green and blue color filters and a second black matrix between the red, green and blue color filters. The second black matrix is used to isolate the red, green and blue color filters from each other.
[0052] see Image 6 As shown, it is a schematic diagram of the layout structure of the color filter layer, the first black matrix and the second black matrix, wherein R is a reflective area, T is a transmiss...
