Abstract

A transflective liquid crystal display (LCD) includes at least a transmission pixel region and at least a reflection pixel region positioned in a pixel region. The transmission region includes at least a transmissive electrode connected to a first switching element. The reflection pixel region includes at least a reflective electrode connected to a second switching element. The transmissive and the reflective electrodes are controlled respectively by independent switching elements.

Claims (16)

1. A transflective liquid crystal display (LCD) including at least a reflection region and a transmission region positioned in a pixel region of the transflective liquid crystal display, wherein the reflection region includes at least a reflective electrode connected to a first switching element, and the transmission region includes at least a transmissive electrode connected to a second switching element, the first switching element and the second switching element are connected to the same data line and are respectively connected to a first scan line and a second scan line that are not electrically connected to each other, and the transmissive electrode is located in a bottom layer of the second switching element.

2. The transflective LCD of claim 1 , wherein the pixel region is a red color pixel region.

3. The transflective LCD of claim 1 , wherein the pixel region is a green color pixel region.

4. The transflective LCD of claim 1 , wherein the pixel region is a blue color pixel region.

5. The transflective LCD of claim 1 , wherein the first switching element is used to control a reflection mode of the transflective LCD, and the second switching element is used to control a transmission mode of the transflective LCD.

6. The transflective LCD of claim 5 , wherein the reflection mode and the transmission mode are operated individually or cooperatively to achieve best display effect.

7. The transflective LCD of claim 1 , wherein the second switching element is located under the reflective electrode to avoid affecting the aperture ratio of the transflective LCD.

8. The transflective LCD of claim 1 , wherein the transmissive electrode is connected to an active layer of the second switching element.

9. A transflective liquid crystal display (LCD) including at least a reflection region and a transmission region positioned in a pixel region of the transflective liquid crystal display, wherein the reflection region includes at least a reflective electrode connected to a first switching element, and the transmission region includes, at least a transmissive electrode connected to a second switching element, the first switching element and the second switching element are connected to the same data line and are respectively connected to a first scan line and a second scan line that are not electrically connected to each other, and the transmissive electrode, the first scan line, and the second scan line are located in the same layer.

10. The transflective LCD of claim 9 , wherein the pixel region is a red color pixel region.

11. The transflective LCD of claim 9 , wherein the pixel region is a green color pixel region.

12. The transflective LCD of claim 9 , wherein the pixel region is a blue color pixel region.

13. The transflective LCD of claim 9 , wherein the first switching element is used to control a reflection mode of the transflective LCD, and the second switching element is used to control a transmission mode of the transflective LCD.

14. The transflective LCD of claim 13 , wherein the reflection mode and the transmission mode are operated individually or cooperatively to achieve best display effect.

15. The transflective LCD of claim 9 , wherein the second switching element is located under the reflective electrode to avoid affecting the aperture ratio of the transflective LCD.

16. The transflective LCD of claim 9 , wherein the transmissive electrode is connected to an active layer of the second switching element.
