Description

M421514 V. New description: [New technology technology] [0001] The present invention relates to a panel device, and more particularly to a panel device having a planar and stereoscopic display mode, and can switch between flat or stereoscopic display. [Prior Art] [Acid] The existing stereoscopic (3_Dimensi〇ns) display technology can be divided into two categories: the naked eye type and the glasses type. The two main principles are similar. The purpose is to allow the left and right eyes to receive the parallax separately. Image to create a three-dimensional sense in the brain. The device whose technical focus is on the former is a liquid crystal display, and the latter is a stereoscopic display glasses. In the home audio-visual environment, the naked-eye stereoscopic display technology is one of the current mainstream developments. At present, the naked-eye technology includes a lenticular lens (Lenticuiai Lens), a barrier grating (Parallax Barrier), and a pointing light source (Directi〇nai Backlight). The technical principle of the frog mirror grating is to use light refraction to allow left and right eyes to see. The effect of stereo imaging is achieved because of the different images produced by different angles of refraction. [0003] Home displays generally do not only serve as stereoscopic displays, and therefore require a switching mechanism for planar and stereoscopic display modes. Referring to the figure, a conventional panel device having a planar and stereoscopic display mode is illustrated. The switching mechanism is to increase the switching of the liquid crystal layer (Switch Cell) between the lenticular grating and the liquid crystal display panel (LCD panel). The switching liquid crystal layer has a glass substrate group 120 including a first glass substrate 121 and a second glass substrate 122; above the first glass substrate 121 is a lenticular lens 110, a first glass substrate 121 and a lenticular lens 11 ( The first form number A0101 is the fourth page/the total of 18 sheets of the interlayer layer 131, and the lenticular lens 110 is an external glass-filled substrate 100. The display panel includes a glass substrate group 140 and a polarizing plate group 150, and the glass plate 140 includes a third glass substrate and a fourth glass substrate. The polarizing plate stage 150 includes a first polarizing plate 151 and a second polarizing plate 152. The first polarizing plate 151 is attached to the upper side of the third glass substrate 141, and the first polarizing plate 152 is attached to the lower side of the fourth glass substrate 142. The first polarizer 151 is disposed under the second glass substrate 122 and the second spacer layer us is sandwiched between the first polarizer 151 and the second ramp substrate 122; and a set of backlight modules is disposed under the second polarizer 152 Group 16〇. For example, in the twisted nematic switching liquid crystal layer, when the light in the polarization direction enters the switching liquid crystal layer, the polarization direction is rotated by 90 degrees, which is due to the lenticular lens in the lenticular lens 11Q. The refractive indices of the internal liquid crystal and the lens are different, and an optical path difference is generated, thereby producing a stereoscopic display effect. If the voltage is applied to the liquid crystal layer, the liquid crystal molecules change the alignment direction so that the light is maintained at 0 degree by switching the polarization direction of the liquid crystal layer. This is because the internal liquid crystal and the lens of the lenticular lens in the lenticular lens 11() The refractive index is the same and does not produce an optical path difference, thus producing a flat® display. [0005] The above-mentioned conventional lenticular grating switching mechanism is a three-layer structure, and the technology is directly embodied on the display to directly increase the thickness; in addition, the name and process part of the 'three-layer structure requires two pairs. Group, accuracy is difficult to control. From this point of view, a more compact panel device having a planar and stereoscopic display mode is desirable. [New Content] [0006] In view of this, the purpose of this creation is to propose a panel device having a plane and vertical form number Α0101, page 5/18 pages [0007] M421514 body display mode, the purpose of which is to simplify the conventional knowledge.

Lenticular Lens), switching the liquid crystal layer (Switch Cell), liquid crystal display panel (LCD Pane 1). Among them, the main structure for switching the liquid crystal layer includes an upper glass substrate (Bottom Ce 11), an upper alignment film, a lower alignment film, a thin film (Thin-Film Transistor), and a liquid crystal layer. The liquid crystal layer is located between the upper glass substrate and the lower glass substrate. An upper alignment film disposed between the upper glass substrate and the liquid crystal layer is disposed under the upper glass substrate and above the liquid crystal layer; and a lower alignment film and a thin film transistor are included between the lower glass substrate and the liquid crystal layer, and the thin film transistor is formed Located below the lower glass substrate and below the lower alignment film, the lower alignment film is disposed under the liquid crystal layer. Wherein the function of the alignment film is to maintain the direction of the liquid crystal molecules to which no voltage is applied. The function of the thin film transistor is to apply a voltage to control the rotation angle of the liquid crystal molecules. [0008] The liquid crystal display panel is located above the switching liquid crystal layer, and its main structure includes There is an upper glass substrate and a lower glass substrate. In the present creation, the lower glass substrate of the liquid crystal display panel is simultaneously an upper glass substrate for switching the liquid crystal layer. The reason is that the upper glass substrate of the liquid crystal layer is switched, and only one layer of the alignment film is provided on the lower side thereof.

[0015] A polarizing plate group 330 is included for polarizing light that penetrates the polarizing plate group 330. It has a first polarizing plate 331 and a second polarizing plate 332.

'The light then enters the liquid crystal display panel to produce different colors and shades, and then the light enters the lenticular grating 21〇. This is because the refractive indices of the internal liquid crystal and the lens of the lenticular lens in the lenticular lens 21〇 are different. The optical path difference is generated, and the light entering the lenticular grating 210 from different positions produces refraction at different angles, thereby producing a stereoscopic display effect. If the second thin film transistor 402 applies a voltage to the second liquid crystal layer 4〇1' at this time, the liquid crystal molecules of the second liquid crystal layer 401 change the alignment direction, and when the polarized light of 0 degree enters the second liquid crystal layer 401, the light is incident. The polarization direction maintains the twist, and then the light enters the liquid crystal display panel layer to produce different colors and shades, and then the light enters the lenticular grating 210, which is due to the internal liquid crystal of the lenticular lens in the lenticular grating 210. The refractive index of the lens is the same, and the optical path difference is not generated. The light entering the lenticular lens 21 from different positions is not refracted, thus producing a flat display effect. In summary, the present invention is a panel device having a flat and stereoscopic display mode, which is more compact than the conventional panel device, because the integrated design of the creation can reduce the structure of one layer and effectively reduce the display. Thickness; in terms of process, since the switching process of the liquid crystal layer and the M421.514 liquid crystal display panel of the form number Α0101 page 10/18 is omitted, the material can be saved and the cost can be reduced, and the group offset can be avoided. The stereo effect enhances accuracy.
