The first pixel electrode PE1 and the second pixel electrode PE2 may be, for example, a metal oxide conductive material (eg, indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide). Or other suitable transparent conductive materials. The material of the first reflective electrode RE1 and the second reflective electrode RE2 may be, for example, a metal, a metal nitride, a metal oxide, a metal oxynitride, or a combination thereof.

In this embodiment, two first reflective electrodes RE11, RE12 of the first reflective electrode RE1 are connected to each other. In detail, the first reflective electrode RE1 may further include a reflective electrode connection line RE13 for connecting the two first reflective electrodes RE11 and RE12, and the reflective electrode connection line RE13 crosses the second display block 22 to connect to each of the two Two first reflective electrodes RE11, RE12 in each of the first display blocks 12, 14. The reflective electrode connection line RE13 may be linear, for example, and one side of the reflective electrode connection line RE13 may be aligned with one side of the two first reflective electrodes RE11 and RE12, so that the first reflective electrode RE1 is “ㄈ” "Font, but this new creation is not limited to this. In addition, since the first reflective electrode RE1 includes a reflective electrode connecting line RE13 across the second display block 22, the width (or length) of the second reflective electrode RE2 needs to be reduced so that its width is slightly smaller than that of the first reflective electrode RE11, The width (or length) of RE12 to prevent the second reflective electrode RE2 from being electrically connected to the first reflective electrodes RE11 and RE12 through the reflective electrode connection line RE13 and causing a short circuit. It should be particularly noted here that although the width (or length) of the second reflective electrode RE2 needs to be reduced, its corresponding length (or width) can be increased to make the size of the second reflective electrode RE2 and the first reflective electrode RE11 The sizes of RE12 and RE12 are substantially the same to prevent the first grayscale display area 10 and the second grayscale display area 20 from having different reflectances.

In some embodiments, the first conductive electrode E1 and the second conductive electrode E2 are electrically connected to the first active element T1 and the second active element T2, respectively.

Since the two first reflective electrodes RE11, RE12 in the first reflective electrode RE1 of this embodiment are connected to each other (ie, the first conductive electrodes E1 respectively provided in the two first display blocks 12, 14 are connected to each other), Therefore, the first contact window H1 may be located only in one of the two first display blocks 12 and 14 of the first gray-scale display area 10, so that the first active element T1 communicates with the first active window T1 through the first contact window H1. A conductive electrode E1 is electrically connected. In this embodiment, the first contact window H1 is located in the first display block 12, but the novel creation is not limited to this. The second contact window H2 is located in the second gray-scale display area 20, for example. In detail, the second contact window H2 is located in the second display block 22, for example, so that the second active device T2 is electrically connected to the second conductive electrode E2 through the second contact window H2.

Since the first conductive electrode E1 is electrically connected to the first active element T1, the first active element T1 provided in the first display block 12 can provide a voltage to the first grayscale display region 10 (including two The first pixel electrode PE1 in the first display blocks 12 and 14), so that the first pixel electrode PE1 and the first common electrode have different operating voltages, and the liquid crystal corresponding to the first grayscale display region 10 is driven. The molecules rotate to make the first gray-scale display area 10 bright. Similarly, since the second conductive electrode E2 is electrically connected to the second active element T2, the second active element T2 provided in the first display block 14 can provide a voltage to the second grayscale display region 20 ( Including a second pixel electrode PE2 in a second display block 22), so that the second pixel electrode PE2 and the second common electrode have different operating voltages to drive the liquid crystal corresponding to the second grayscale display region 20 The molecules rotate to make the second gray-scale display area 20 bright.

In short, when the first active element T1 and the second active element T2 are turned on at the same time, three display blocks (two first display blocks 12, 14 and one second display block 22) can be made bright. When the first active element T1 is turned on and the second active element T2 is turned off, two display blocks (the two first display blocks 12, 14) can be made bright. When the first active element T1 is turned off and the first active element T1 is turned on When two active elements T2 are used, one display block (two and one second display block 22) can be made bright, and when the first active element T2 and the second active element T2 are turned off, the above three displays can be made. The block is dark. Therefore, without changing the voltage provided by the first active element T2 or the second active element T2, the first active element T2 or the second active element T2 can be turned on or off to display gray levels with different brightness. Video, so the power consumption of the display panel including the pixel structure PX1 of this embodiment can be saved.

The first drain extensions 132 and 134 are, for example, the same film layer (second metal layer 130) as the second drain extension 136, and the first and second drain extensions 132 and 134 and 136 are, for example, Each is electrically connected to the first active element T1 and the second active element T2. In this embodiment, since the second active element T2 and the second pixel electrode PE2 are located in different display blocks, the second active element T2 can be extended from the second drain electrode D2 to the second display block 22 The second drain extension 136 is electrically connected to the second pixel electrode PE2, so that the second active device T2 can provide a voltage to the second pixel electrode PE2 located in the second display block 22.

In general, the first drain extensions 132 and 134 may form a storage capacitor with the first metal layer 110 and the first insulating layer 120 therebetween, for example. The storage capacitor can be used to store voltage, and the stored voltage can affect the deflection state of the liquid crystal molecules. Therefore, the storage capacitor can be used to further control the grayscale images with different brightness.

In this embodiment, the pixel structure includes two first display blocks and a second display block located therebetween. By making the first display block or the second display block appear bright or dark, Various combinations can display grayscale images with different brightness.
