Stereoscopic display

The present invention relates to a display, and more particularly to a stereoscopic display.

With the advancement of display technology, people can make life more convenient by the aid of display devices. In order to make the display light and thin, the flat panel display has become the mainstream. Among many flat panel displays, liquid crystal displays have superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference, so liquid crystal displays are popular among consumers.

Referring to FIG. 1, a conventional liquid crystal display 1 includes a plurality of pixel units 11 and a plurality of common electrode lines 12 electrically connected to the pixel units 11 and located on upper and lower sides of the pixel units 11, respectively.

With the advancement of 3D stereoscopic display technology in recent years, more and more operators have invested in the manufacture of the stereoscopic display 100 shown in FIG. 2 in recent years. The difference between the conventional stereoscopic display 100 and the liquid crystal display 1 of FIG. 1 is that the stereoscopic display 100 is more A phase retardation film 16 is disposed on the pixel unit 11 and includes a plurality of delay regions 161, and the delay region 161 is located between every two gate lines 14.

The pixel period of the pixel unit 11 in the odd-numbered (Odd) delay region 161 is controlled to match the pixel period of the pixel unit 11 in the adjacent even-numbered (Even) delay region 161, and the phase retardation film 16 is used. In the case where each pattern has a different optical axis direction, the original 2D picture can be changed to a 3D picture, and since the odd-numbered (Odd) delay area 161 and the even-numbered (even) delay area 161 of the pixel unit 11 are required to generate a 3D picture, The resolution of FIG. 2 becomes two pixel units 11 of two rows and three columns, that is, in the case of the pixel unit 11 of the same row or column number, the display pixel of the stereoscopic display 100 is the existing one. Half of the liquid crystal display 1.

Accordingly, it is an object of the present invention to provide a stereoscopic display having high resolution.

Accordingly, the stereoscopic display of the present invention includes a plurality of pixel units, a plurality of common electrode lines, a plurality of data lines, a plurality of gate lines, a plurality of switching elements, and a phase retardation film.

The common electrode lines are electrically connected to the pixel units and are located on opposite sides of the pixel units. The data lines are electrically connected to the pixel units and are located on opposite sides of the pixel units.

The gate lines are electrically connected to the pixel units and respectively located in the middle of the pixel units, and the gate lines are respectively divided into two parts.

The switching elements are electrically connected to the gate lines and the data lines, respectively. The phase retardation film is disposed on the pixel units and includes a plurality of delay regions of different phases, and each of the delay regions is located between the two gate lines.

The effect of the present invention is that the gate lines are electrically connected to the pixel units respectively and are respectively located in the middle of the pixel units, and the pixel unit is divided into two parts, and then the phase delay film is delayed. The regions are respectively disposed on the pixel units and located between the gate lines, thereby enabling finer control of the pixel units, and enabling the human eye to receive images in a skipped manner, thereby improving The resolution of the stereoscopic display.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 3, a preferred embodiment of the stereoscopic display 2 of the present invention includes a plurality of pixel units 3, a plurality of common electrode lines 4, a plurality of data lines 5, a plurality of gate lines 6, and a plurality of switching elements 7, And a phase retardation film 8.

The common electrode lines 4 are electrically connected to the pixel units 3 and located on opposite sides of the pixel units 3, and the data lines 5 are electrically connected to the pixel units 3 and located in the pixels. The other two opposite sides of the unit 3 are electrically connected to the pixel units 3 and respectively located in the middle of the pixel units 3, and the gate lines 6 respectively distinguish the pixel units 3 In addition, the switching elements 7 are electrically connected to the gate lines 6 and the data lines 5, respectively, and the phase retardation film 8 is disposed on the pixel units 3, and the phase retardation film 8 is disposed. A delay region 81 comprising a plurality of different phases and located between the two gate lines 6 is included. In the present embodiment, the pixel units 3 are rectangular, and the switching elements 7 are all used in the use of a gold-oxygen half-field transistor, and signals are transmitted from the gate lines 6 to each switching element 7. In order to control the opening and closing of the switching elements 7, another signal is also transmitted to each pixel unit 3 via the data lines 5. If the switching element 7 is on, the pixel unit 3 is in accordance with the data line 5. The signal action, if the switching element 7 is off, the pixel unit 3 will not operate according to the signal of the data line 5, and when the pixel unit 3 is activated, the delay region on the phase retardation film 8 can be used. 81, and the relative position of each of the delay regions 81 and the pixel units 3 causes the pixel units 3 to be skipped during operation, and the user has to wear different left and right eyes with different polarization characteristics when viewing the image. The glasses can achieve the effect of 3D stereo.

The gate lines 6 are electrically connected to the pixel units 3 and respectively located in the middle of the pixel units 3, and the pixel unit 3 is divided into two parts, and then the phase retardation film 8 is delayed. The regions 81 are respectively disposed on the pixel units 3 and located between the gate lines 6, since each pixel unit 3 is divided into two thinner portions, and each delay region 8 is different in phase. Thereby, the pixel units can be controlled more finely, and the order in which the human eye receives the images can be presented in a skipped manner, thereby improving the resolution of the stereoscopic display 2.

For convenience of explanation, the following comparison is made with three pixel units 3. As can be seen from FIG. 4, the resolution of the liquid crystal display 91 is three pixel units 3; for the three pixel units 3 of the existing stereo display 92, The three delay regions 922 of the phase retardation film 921 can only distinguish a set of matched odd (Odd) and even (Even) delay regions 922, and a single odd (Odd) delay region 922, thus, the existing stereo The resolution of the display 92 can be regarded as 1.5 pixel units; and for the three pixel units 3 of the stereoscopic display 2 of the present invention, the four delay regions 81 of the phase retardation film 8 can be divided into three groups to be matched. The odd-numbered (Odd) and even-numbered (Even) delay regions 81, therefore, the resolution of the stereoscopic display 2 of the present invention is three pixel units, which is twice the resolution of the conventional stereoscopic display 92.

In summary, the stereoscopic display 2 of the present invention can divide each pixel unit 3 into finer by arranging the gate lines 6, the relative positions of the pixel units 3 and the phase retardation films 8. In two parts, the order in which the human eye can receive the image is presented in a skipped manner, and the resolution of the stereoscopic display 2 can be improved, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
