Description of the Invention: [Technical Field] The present invention relates to a driving method of a display, and more particularly to a driving method of a stereoscopic display. [Prior Art] Referring to Fig. 1', a conventional stereoscopic display 1 includes a flat display device n and a retardation film 12 disposed on the flat display device 11. The retardation film 12 includes a plurality of pattern portions 122 periodically arranged on a film body 2121. By the retardation film 12, the light is caused to have different polarization states, and then interact with the 3D glasses (not shown), so that the left and right eyes of the user can receive different light rays to generate a 3D visual effect. However, the conventional stereoscopic display 1 has a problem that the viewing angle is small in the 3D use state. Therefore, the manufacturer has proposed another high-view stereoscopic display 2 as shown in FIG. 2 to improve the above-mentioned small viewing angle. The conventional high-angle stereoscopic display 2 includes a plurality of shielding layers 22 which are disposed on the retardation film 21 at intervals. 'Each shielding layer 22 is located between every two adjacent pattern portions 211, thereby achieving the purpose of enhancing the viewing angle in the 3D state. Referring to Fig. 2 and Fig. 3, the conventional high-view stereoscopic display 2 may cause a decrease in transmittance due to a decrease in the transmittance due to the setting of the shielding layer 22 when it is used in the 2D state. Therefore, how to improve the above-mentioned shortcomings has been an important goal of the continuous efforts of the technical field. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method of driving a stereoscopic display that produces a 3 201227669 masking area in a controlled manner. The driving method of the stereoscopic display of the present invention comprises a preparation step, a 2D driving step, and a 3D driving step. The preparation step is to prepare a stereoscopic display having a plurality of display blocks, each display block having a first pixel '-second pixel, a second pixel, and a fourth pixel. The 2D driving step drives the first pixel and the second pixel of the display block with a high enable voltage, and drives the second pixel and the fourth picture with a low enable voltage. Prime. The 3D driving step is to drive the first pixel and the third pixel of the display block with the high enable voltage, and the second and fourth pixels are not enabled. The effect of the present invention is that in the 3D driving step, the second pixel and the fourth pixel which are not enabled are used as the masking area to improve the viewing angle. In the 2D driving step, the second halogen and the fourth halogen are driven by the low enable voltage to increase the overall light transmittance. 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. 4, a first preferred embodiment of the driving method of the stereoscopic display of the present invention includes a preparation step 91, a 2D driving step 92, and a -3D driving step 93. Referring to Figures 5 and 6, and in conjunction with Figure 4, the preparation step 91 is to prepare a stereoscopic display 3 having a 201227669 majority display block 3 1 first draw 1 . Each display block 31 has a second time pixel 312, a third time picture, and a fourth time pixel 314. The 杲 red portion M5, - 2 mother-display block 31, which is specifically described by the halogen element 313, has a blue portion 3 that emits red light: a green portion 316' that emits green light and - can emit blue. The mother-red part 315, the green part 316, 317疋 and the corresponding first-order element, the second pixel 312 three-dimensional element 313, the fourth 4th check-in brother-" overlapping. In particular, the control methods of color & are well known to those of ordinary skill in the art, and are not the main technical features of the present invention, and therefore, * are described in more detail. In addition, the stereoscopic display 11 3 used in the present invention is a phase difference film that cooperates with 3D glasses (not shown) to produce a 3D visual effect, but the technique of generating a stereoscopic effect is easy for those having ordinary knowledge in the art. I know, so I won’t add more details.

Specifically, it is of course also possible to switch directly to the 3D driving step 93 by the 2D driving step 92, or directly switch to the 2D driving step 92 by the 3D driving step 93. Referring to FIG. 7 and FIG. 8, in the 2D driving step 92 (see FIG. 4), the first pixel 311 and the third pixel 313' of the display block 31 are driven by a high enable voltage 4. At the same time, the second pixel 312 and the fourth pixel 314 are driven by a low enable voltage 5. In the 2D use state, each of the first pixel 311, the second pixel 312, the third pixel 313, and the fourth pixel 314 are in a state of being able to transmit light, so that the light transmittance is better. In 201227669, it is possible to avoid the problem that the existing high-angle stereoscopic display 2 shown in FIG. 2 has insufficient light transmittance and affects brightness in the case of 2D use. In particular, in FIG. 8, for convenience of description, only the first pixel 311 and the second pixel 312 are shown, and the third pixel 313 is similar to the fourth pixel 314. The operating mode is driven. Referring to FIG. 9 and FIG. 10, in the 3D driving step 93 (see FIG. 4), the first pixel first pixel 313 of the display block 驱动 is driven by the high enable voltage 4, without causing The energy level 6 is such that the second pixel 312 and the fourth pixel 314 do not emit light, so each second pixel; 312, the fourth pixel 314 are displayed; a. , Α *''' …,color. In the preferred embodiment, the first human element 311 can cooperate with 3D glasses (not shown) to allow the user's right eye to receive light, and the first _ + brother-one-human pixel The 312 can match the 3D glasses 5 and let the left eye of the (4) receive the light. The black (four) quadratic pixel 312 and the fourth pixel 314 are used as + to improve the disadvantage that the conventional display device 1 shown in Fig. 1 has insufficient viewing angle in the 3D use state. Specifically, the first and second pixels 312' are shown in Fig. 1G for convenience of explanation. Of course, the third pixel 313 and the fourth pixel 314 are driven in a similar operation mode. Therefore, the driving method of the stereoscopic display of the present invention simulates the effect of the shielding layer 22 as shown in FIG. 3 by means of electronic control, so that the vertical M (four) 3 of the present invention does not require additional processes or components to cause additional:: The shielding function with the existing high-angle stereoscopic display 3 can be achieved. In summary, in the driving method of the stereoscopic display of the present invention, in the driving step 9327, the second pixel 312 and the fourth pixel 314 of the non-energized 6 are used as the shielding area to improve the viewing angle. In the 2D driving step w, the second pixel 312 and the fourth pixel 314 are driven by the low enable voltage 5 to increase the overall light transmittance, so that the object of the present invention can be achieved. However, the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes made by the scope of the invention and the description of the invention. Modifications are still within the scope of the invention.
