Description

display device

[0001] The present disclosure relates to a display device.

[0002] To enlarge the reconstructed image of an electro-hologram using a high-resolution liquid crystal panel as a display device, a larger screen is required. One method for achieving this is the tiling technique, in which multiple high-resolution liquid crystal panels are two-dimensionally bonded together. However, if the frame of the high-resolution liquid crystal panel is wide, slits will appear in the displayed image, compromising the in-plane uniformity.

[0003] Patent Document 1 below discloses a display device. In this display device, a driving circuit having a stacked structure is arranged around the periphery of a display area (pixel area). In other words, the driving circuit is divided, and each divided driving circuit is stacked vertically. With a display device configured in this way, the area occupied by the driving circuit is reduced, making it possible to achieve a narrower frame.

[0018] 1. First Embodiment A display device 1 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 6. The display device 1 according to the first embodiment is an example in which the present technology is applied to a vertical drive circuit. Here, the arrow X direction shown as appropriate in the drawings indicates one planar direction of the display device 1 placed on a flat surface for convenience. The arrow Y direction indicates another planar direction perpendicular to the arrow X direction. Furthermore, the arrow Z direction indicates an upward direction perpendicular to the arrow X direction and the arrow Y direction. In other words, the arrow X direction, the arrow Y direction, and the arrow Z direction exactly correspond to the X-axis direction, the Y-axis direction, and the Z-axis direction, respectively, of a three-dimensional coordinate system. Note that these directions are shown to facilitate understanding of the description and do not limit the directions of the present technology.

[0019] [Configuration of Display Device 1] (1) Overall Configuration of Display Device 1 Fig. 1 shows an example of a planar configuration of the overall configuration of a display device 1 according to the first embodiment. In other words, Fig. 1 shows an example of a chip layout of the display device 1.

[0020] The display device 1 according to the present disclosure is constructed as a high-resolution liquid crystal panel in which a plurality of pixels are formed using liquid crystal. This will be described in detail below. In the present disclosure, the display device 1 may be a panel in which pixels having one or more structures selected from organic electroluminescence, organic light-emitting diodes, light-emitting polymers, and light-emitting diodes are formed.

[0021] 1 , the display device 1 is configured using a base 10 as a base. The display device 1 includes a first pixel region 21 and a second pixel region 22 on the base 10. The display device 1 also includes a first drive circuit 301 and a third drive circuit 303, a second drive circuit 302 and a fourth drive circuit 304, a thirteenth drive circuit 313 and a fourteenth drive circuit 314, and a fifteenth drive circuit 315 and a sixteenth drive circuit 316 on the base 10. The display device 1 also includes an internal memory 4, a first timing generation circuit 51, and a second timing generation circuit 52 on the base 10.

[0022] (2) Structure of the Base 10 Although illustration and description of the cross-sectional structure are omitted, the base 10 is formed, for example, with a silicon substrate, a transparent glass substrate, and liquid crystal sealed between these two substrates. As shown in Fig. 1, the base 10 is formed, for example, in a rectangular shape when viewed from the direction of arrow Z (hereinafter simply referred to as "in a plan view"). The planar shape of the base 10 may be formed in a polygonal, circular, or elliptical shape.

[0023] (3) Configuration of the First Pixel Region 21 and the Second Pixel Region 22 The first pixel region 21 and the second pixel region 22 are disposed in the center of the base 10 in a plan view. A detailed explanation will be given. The first pixel region 21 and the second pixel region 22 are formed by dividing what is essentially one pixel region into two regions, and are disposed spaced apart from each other in the direction of the arrow X. That is, the first pixel region 21 is disposed on the left side of the base 10, and the second pixel region 22 is disposed on the right side of the base 10, spaced apart from the first pixel region 21 in the direction of the arrow X.

[0024] Hereinafter, the direction of arrow X will be simply referred to as the "first direction." This first direction corresponds to the "first direction" according to the present technology. Furthermore, the direction of arrow Y will be simply referred to as the "second direction." This second direction corresponds to the "second direction" according to the present technology. Note that in the present disclosure, the "first direction" may be read as the "second direction," and the "second direction" may be read as the "first direction."

[0025] In the first pixel region 21, a plurality of first pixels 211 that emit light are arranged in a matrix in a first direction and a second direction. Although detailed structure and description will be omitted, as described above, the display device 1 employs a liquid crystal structure, and therefore the first pixels 211 are formed, for example, by a series circuit of a liquid crystal element and a pixel transistor. In the first embodiment, in the first pixel region 21, for example, 1K (K=1000) first pixels 211 are arranged in the first direction, and for example, 2K first pixels 211 are arranged in the second direction (1K×2K).

[0026] In the second pixel region 22, a plurality of second pixels 221 that emit light are arranged in a matrix in the first and second directions, similar to the first pixels 211. The second pixels 221 are formed with the same structure as the first pixels 211. In the first embodiment, similar to the first pixel region 21, in the second pixel region 22, 1K second pixels 221 are arranged in the first direction and 2K second pixels 221 are arranged in the second direction (1K×2K).

[0027] (4) Configuration of the First Drive Circuit 301 and the Third Drive Circuit 303 The first drive circuit 301 and the third drive circuit 303 are configured as vertical drive circuits for the first pixel region 21. The first drive circuit 301 and the third drive circuit 303 are arranged by dividing one vertical drive circuit for the first pixel region 21 into two. This will be explained in detail.

[0028] The first drive circuit 301 is disposed on the right side of the first pixel region 21, between the first pixel region 21 and the second pixel region 22. The first drive circuit 301 is disposed along the right side of the first pixel region 21. The first drive circuit 301 is electrically connected to the first pixels 211 in the even-numbered rows arranged in the second direction of the first pixel region 21, and is also electrically connected to a plurality of first pixels 211 arranged in the even-numbered rows in the first direction. The plurality of first pixels 211 arranged in the first direction are electrically connected via vertical signal lines (vertical scanning lines) VL. Detailed circuit configurations of the first drive circuit 301 and the second drive circuit 302 will be described later.

[0029] The third drive circuit 303 is disposed on the left side of the first pixel region 21 along the left edge of the first pixel region 21. The third drive circuit 303 is electrically connected to the first pixels 211 in odd-numbered rows arranged in the second direction of the first pixel region 21, and is also electrically connected to a plurality of first pixels 211 arranged in the odd-numbered rows in the first direction. The plurality of first pixels 211 arranged in the first direction are electrically connected through vertical signal lines VL. The odd-numbered rows are adjacent to the even-numbered rows in the second direction. In the first embodiment and the embodiments described below, the configurations of "even-numbered rows" and "odd-numbered rows" are merely examples. For example, the "even-numbered rows" and "odd-numbered rows" may be interchanged in each of the first drive circuit 301 and the third drive circuit 303. The "even-numbered rows" may also refer to, for example, two or more rows of pixels arranged in the second direction. The same applies to "odd-numbered rows."

[0030] (5) Configuration of the Second Drive Circuit 302 and the Fourth Drive Circuit 304 The second drive circuit 302 and the fourth drive circuit 304 are configured as one vertical drive circuit for the second pixel region 22. The second drive circuit 302 and the fourth drive circuit 304 are arranged by dividing one vertical drive circuit for the second pixel region 22 into two.

[0031] The second driving circuit 302 is disposed on the left side of the second pixel region 22, between the first pixel region 21 and the second pixel region 22. The second driving circuit 302 is further disposed along the left edge of the second pixel region 22. More specifically, the second driving circuit 302 is disposed between the first driving circuit 301 and the second pixel region 22, partially overlapping the first driving circuit 301. The second driving circuit 302 is electrically connected to the second pixels 221 in the even-numbered rows arranged in the second direction of the second pixel region 22, and is also electrically connected to a plurality of second pixels 221 arranged in the even-numbered rows in the first direction. The plurality of second pixels 221 arranged in the first direction are electrically connected via a vertical signal line VL.

[0032] The fourth drive circuit 304 is disposed on the right side of the second pixel region 22 along the right side of the second pixel region 22. The fourth drive circuit 304 is electrically connected to the second pixels 221 in the odd-numbered rows arranged in the second direction of the second pixel region 22, and is also electrically connected to the plurality of second pixels 221 arranged in the odd-numbered rows in the first direction. The plurality of second pixels 221 arranged in the first direction are electrically connected via the vertical signal line VL.

[0033] (6) Specific Configuration of First Drive Circuit 301 and Second Drive Circuit 302 Fig. 2 shows an example of a block configuration of the first drive circuit 301 and the second drive circuit 302. As shown in Fig. 2, a plurality of wirings 300 are arranged between the first pixel region 21 and the second pixel region 22, and the wirings 300 extend in the second direction. In other words, the space between the first pixel region 21 and the second pixel region 22 is used as a region for arranging the first drive circuit 301 and the second drive circuit 302, and is also used as a region for extending the wirings 300.

[0034] The wiring 300 includes a control signal line RVS, a control signal line xRVS, an input pulse signal line IN1, an output pulse signal line NXT1, an input pulse signal line IN2, an output pulse signal line NXT2, a clock signal line CLK, a reset signal line RST, an output signal line OUT1, and an output signal line OUT2.

[0035] The control signal line RVS transfers a signal that controls the transfer direction of the vertical scanning signal. The control signal line xRVS transfers a signal that is opposite in phase to the signal transferred to the control signal line RVS. The input pulse signal line IN1 transfers an input pulse signal in the forward transfer direction (here, scanning in the direction opposite to the second direction). The output pulse signal line NXT1 transfers an output pulse signal in the forward transfer direction. The input pulse signal line IN2 transfers an input pulse signal in the reverse transfer direction (here, scanning in the second direction). The output pulse signal line NXT2 transfers an output pulse signal in the reverse transfer direction.

[0036] The clock signal line CLK transfers a clock signal that indicates transfer timing. The reset signal line RST transfers a reset signal that returns to an initial state. The output signal lines OUT1 and OUT2 transfer transfer signals from the transfer circuit 30 to the first output circuits 31(1) and 31(2), respectively. The output signal lines OUT1 and OUT2 transfer transfer signals from the transfer circuit 30 to the second output circuits 32(1) and 32(2), respectively.

[0037] As shown in FIG. 2 , the first drive circuit 301 and the second drive circuit 302 share a portion of their structure. A detailed description follows. The first drive circuit 301 includes a first output circuit 31 and a transfer circuit 30. The transfer circuit 30 is electrically connected to the control signal line RVS of the aforementioned wiring 300 directly or via a switch SW. The transfer circuit 30 is electrically connected to the first output circuit 31 and controls the second-direction scanning of the vertical drive signal from the first output circuit 31. The first output circuit 31 is electrically connected to a plurality of first pixels 211 in the first pixel region 21 through vertical signal lines VL. The first output circuit 31 outputs drive signals to the plurality of first pixels 211 through the vertical signal lines VL. Note that multiple first output circuits 31 and multiple transfer circuits 30 are arranged in the second direction. For convenience, numbers in parentheses are added to the reference symbols in order. For example, the first output circuits 31 are sequentially represented as the first output circuit 31(1) and the first output circuit 31(2).

[0038] The second drive circuit 302 includes a second output circuit 32 and a transfer circuit 30 shared with the first drive circuit 301. In other words, the transfer circuit 30 is a circuit shared by the first drive circuit 301 and the second drive circuit 302. The transfer circuit 30 is electrically connected to the second output circuit 32 and controls scanning of the vertical drive signal from the second output circuit 32 in the second direction. The second output circuit 32 is electrically connected to a plurality of second pixels 221 in the second pixel region 22 through vertical signal lines VL. The second output circuit 32 outputs drive signals to the plurality of second pixels 221 through the vertical signal lines VL. Similar to the first output circuit 31 and the transfer circuit 30, a plurality of second output circuits 32 are arranged in the second direction, and a number in parentheses is added to the reference numeral.

[0039] Fig. 3 shows an example of a timing chart during forward transfer of the first drive circuit 301 and the second drive circuit 302. Fig. 4 shows an example of a timing chart during reverse transfer of the first drive circuit 301 and the second drive circuit 302.

[0040] During forward transfer, as shown in FIG. 3 , the first drive circuit 301 and the second drive circuit 302 are reset based on a reset signal from the reset signal line RST. Simultaneously with the timing of reset release, the transfer direction (scanning direction) of the first drive circuit 301 and the second drive circuit 302 is determined based on control signals from the control signal line RVS and the control signal line xRVS. That is, in the first drive circuit 301, the transfer circuit 30 determines the operation order of the first output circuit 31(1) and the first output circuit 31(2), thereby determining the scanning direction of the vertical signal line VL. Similarly, in the second drive circuit 302, the transfer circuit 30 determines the operation order of the second output circuit 32(1) and the second output circuit 32(2), thereby determining the scanning direction of the vertical signal line VL.

[0041] During reverse transfer, as shown in FIG. 4 , the first drive circuit 301 and the second drive circuit 302 are reset based on a reset signal from the reset signal line RST. Simultaneously with the timing of reset release, the transfer direction (scanning direction) of the first drive circuit 301 and the second drive circuit 302 is determined based on control signals from the control signal line RVS and the control signal line xRVS. That is, in the first drive circuit 301, the transfer circuit 30 determines the operation order of the first output circuit 31(1) and the first output circuit 31(2), thereby determining the scanning direction of the vertical signal line VL. Similarly, in the second drive circuit 302, the transfer circuit 30 determines the operation order of the second output circuit 32(1) and the second output circuit 32(2), thereby determining the scanning direction of the vertical signal line VL.

[0157] 11, the display device 1 is provided with first pixel region 21 to ninth pixel region 29, each having a pixel count divided into 1K / 2K / 1K, as shown in FIG. 11. Therefore, in the display device 1, the first drive circuit 301 and the like only need to have a drive capability equivalent to 1K, for example, and therefore can achieve a high resolution of 4K x 4K without changing the drive capability.

[0158] 7. Seventh Embodiment Next, a display device 1 according to a seventh embodiment of the present disclosure will be described with reference to Fig. 12. The display device 1 according to the seventh embodiment is an application example of the display device 1 according to the second embodiment.

As shown in Fig. 12, the display device 1 includes a first inspection circuit 351 and a second inspection circuit 352 on the base 10.

[0160] The first inspection circuit 351 is arranged in place of the thirteenth drive circuit 313 of the display device 1 according to the second embodiment. That is, the first inspection circuit 351 is arranged along the upper side of the first pixel region 21, and inspects the first pixel region 21.

[0162] The inspection by the first inspection circuit 351 and the second inspection circuit 352 is performed, for example, before the display device 1 is shipped.

[0163] The other components are the same as or substantially the same as the components of the display device 1 according to the second embodiment.

[0164] [Operational Effects] According to the display device 1 of the seventh embodiment, it is possible to obtain the same operational effects as those obtained by the display device 1 of the second embodiment.

[0165] 12, the display device 1 is provided with the first inspection circuit 351 and the second inspection circuit 352, so that defective products can be rejected and non-defective products can be shipped, thereby improving the product reliability of the display device 1.

[0166] In the display device 1 according to the seventh embodiment, an inspection circuit is provided instead of the horizontal drive circuit, but an inspection circuit may be provided instead of the vertical drive circuit.

[0167] 8. Eighth Embodiment Next, a display device 1 according to an eighth embodiment of the present disclosure will be described with reference to Fig. 13. The display device 1 according to the eighth embodiment is an application example of the display device 1 according to the fourth embodiment.

[0168] [Configuration of Display Device 1] FIG. 13 shows an example of the planar configuration of the overall configuration of the display device 1 according to the eighth embodiment. As shown in FIG. 13, the display device 1 has a configuration similar to that of the display device 1 according to the fourth embodiment. In the display device 1, color mixing allowance regions 360 are arranged. The color mixing allowance regions 360 are formed between the first pixel region 21 and the second pixel region 22, between the third pixel region 23 and the fourth pixel region 24, between the first pixel region 21 and the third pixel region 23, and between the second pixel region 22 and the fourth pixel region 24. In other words, the color mixing allowance regions 360 overlap with and utilize the arrangement regions of the first drive circuit 301 and the like. The color mixing allowance regions 360 are regions in which irradiation of light of different wavelength ranges and color mixing are permitted.

[0169] 5, red light 81R emitted from laser device 811 of light-emitting system 8 is irradiated onto first pixel region 21. Similarly, green light 81G emitted from laser device 812 is irradiated onto second pixel region 22, and blue light 81B emitted from laser device 813 is irradiated onto third pixel region 23. Furthermore, although not described in the light-emitting system 8, yellow light 81Y is irradiated onto fourth pixel region 24.

[0170] Two or more different lights selected from red light 81R, green light 81G, blue light 81B, and yellow light 81Y can be overlappingly emitted in the color mixing permitted region 360. Here, two or more different lights include, for example, irradiating each of two pixel regions with green light 81G instead of yellow light 81Y. In this case, the irradiation intensity of green light 81G can be improved. With the display device 1 configured in this manner, color mixing can be effectively suppressed or prevented.

[0171] 14 to 22, a display device 1 according to a ninth embodiment of the present disclosure will be described. The ninth embodiment describes a ninth example in which inter-area pixels 200 are arranged between pixel regions in the display device 1 according to the first embodiment, and an inter-area driving circuit 371 and an inter-area driving circuit 372 are further arranged.

[0172] [System Configuration of Display Device 1] Fig. 14 shows an example of the system configuration of the display device 1 according to the ninth embodiment. As shown in Fig. 14, the display device 1 includes a drive system 71 and a display area (display panel) 72. Furthermore, the display device 1 includes a video signal generation source 70 as an external device or an internal device. This will be described in detail.

[0173] The video signal generation source 70 outputs input image information (video data) D1 for generating a holographic reproduction image to the display device 1. The input image information D1 includes still image information and moving image information. The video signal generation source 70 also outputs inter-area display information D2 to the display device 1. The inter-area display information D2 is generated based on the input image information D1.

[0174] In the ninth embodiment, the drive system 71 includes a first drive circuit 301 to a fourth drive circuit 304, a thirteenth drive circuit 313 to a sixteenth drive circuit 316, an inter-area drive circuit 371, and an inter-area drive circuit 372. The display area 72 includes a first pixel area 21, a second pixel area 22, and an inter-area pixel area 20.

[0175] Input image information D1 output from the video signal generation source 70 is output to the first drive circuit 301 to the fourth drive circuit 304 and the thirteenth drive circuit 313 to the sixteenth drive circuit 316 of the display device 1. The first pixels 211 of the first pixel region 21 and the second pixels 221 of the second pixel region 22 emit light in response to drive signals from the first drive circuit 301 to the fourth drive circuit 304 and the thirteenth drive circuit 313 to the sixteenth drive circuit 316 based on the input image information D1, and display the input image information D1.

[0176] Furthermore, inter-area display information D2 output from the video signal generating source 70 is output to the inter-area driving circuit 371 and the inter-area driving circuit 372 of the display device 1. The inter-area pixel region 20 is disposed between the first pixel region 21 and the second pixel region 22. One or more inter-area pixels 200 are disposed in the inter-area pixel region 20. The inter-area pixels 200 in the inter-area pixel region 20 emit light in response to drive signals from the inter-area driving circuit 371 and the inter-area driving circuit 372 based on the inter-area display information D2, and display the inter-area display information D2.

[0177] [Overall Configuration of Display Device 1] Fig. 15 shows an example of the planar configuration of the overall configuration of the display device 1. Fig. 16 shows an example of an enlarged planar configuration of a main part of the display device 1. Fig. 17 shows an example of an enlarged cross-sectional configuration of a main part of the display device 1. As shown in Figs. 15 to 17, the display device 1 according to the ninth embodiment is provided with an inter-area pixel region 20. Furthermore, the display device 1 is provided with an inter-area driving circuit 371 and an inter-area driving circuit 372. These will be described in detail below.

[0178] 15 and 16 , the inter-region pixel region 20 is disposed between the first pixel region 21 and the second pixel region 22 in the first direction, and is disposed along the right side of the first pixel region 21 and the left side of the second pixel region 22 in the second direction. The inter-region pixel region 20 is disposed so as to overlap at least a part of the first drive circuit 301 and the second drive circuit 302 described above.

[0179] Inter-region pixels 200 are arranged in the inter-region pixel region 20. Here, a plurality of inter-region pixels 200 are arranged in a matrix in the first and second directions. The longitudinal cross-sectional configuration will be described later, but in the ninth embodiment, the inter-region pixels 200 are formed to have the same planar shape and size as the first pixels 211 and the second pixels 221. When the inter-region pixels 200, the first pixels 211, and the second pixels 221 are formed to have the same planar shape and size, the inter-region pixels 200 can be easily formed.

[0180] Note that the inter-region pixel 200 can be formed with a planar size larger than the planar sizes of the first pixel 211 and the second pixel 221.

Fig. 21 shows an example of a schematic system configuration illustrating the relationship between the input image II and the hologram reproduction image HRI in the display device 1CE according to the comparative example. Fig. 22 shows an example of a hologram reproduction image HRI generated by the display device 1CE according to the comparative example.

[0190] As shown in Fig. 18, an input image II is input to a display device 1CE according to the comparative example. The input image II is an image having a symbol SY corresponding to, for example, the letter "A" in its center. In the display device 1CE, the input image II is divided into two in a first direction by a first pixel (not shown) in a first pixel region 21CE and a second pixel (not shown) in a second pixel region 22CE, and light is emitted from the two pixels, and a hologram reproduction image HRI is projected onto a reproduction image plane Rp. The first pixel region 21CE and the second pixel region 22CE are physically divided in the first direction, and a slit SL exists between the first pixel region 21CE and the second pixel region 22CE.

[0191] When the hologram reconstruction image HRI projected on the reconstruction image plane Rp is viewed Vi, a slit image SLI corresponding to the above-mentioned slit SL is visually recognized in the hologram reconstruction image HRI, as shown in FIG.
