Description

  The present invention relates to a color liquid crystal display device assembly and a light conversion device.

  As a color liquid crystal display device assembly, a transmissive or semi-transmissive type in which a liquid crystal material is sandwiched between two panels laminated so that a transparent glass substrate on which a transparent electrode, an alignment film, etc. are laminated is opposed A transmissive or transflective color liquid crystal display assembly comprising a color liquid crystal display device and a planar light source device disposed under the color liquid crystal display device to illuminate the color liquid crystal display device is well known. is there.

  As the planar light source device, two types of planar light source devices (backlights), that is, a direct type planar light source device disclosed in, for example, Japanese Utility Model Laid-Open No. 63-187120 and Japanese Patent Laid-Open No. 2002-277870, An edge light type (also called side light type) planar light source device disclosed in 2002-131552 is well known. As shown in the conceptual diagram of FIG. 31A, the direct-type planar light source device is disposed in the light source 800 disposed in the housing 802 and the housing portion positioned below the light source 800. A reflection member 803 that reflects light emitted from the light source 800 upward, and a housing opening located above the light source 800, passes through while diffusing the light emitted from the light source 800 and the reflection light from the reflection member 803. And a diffusion plate 801 to be made. On the other hand, the edge light type planar light source device includes a light guide plate 901 and a light source 900 composed of a lamp disposed on the side surface of the light guide plate 901 as shown in a conceptual diagram in FIG. . A reflective member 902 is disposed below the light guide plate, and a diffusion sheet 903 and a prism sheet 904 are disposed above the light guide plate.

  The light source is composed of, for example, a cold cathode fluorescent lamp and emits white light. More specifically, in a cold cathode fluorescent lamp, a mixed rare gas such as neon gas or argon is sealed inside, or mercury is diffusely sealed. Then, the ultraviolet light from the mixed rare gas or mercury atom excited due to the glow discharge is applied to the inner surface of the glass tube constituting the fluorescent lamp, the red light emitting phosphor particles, the green light emitting phosphor particles, and the blue light emitting fluorescence. The body particles are excited, and white color is obtained by the emission color from these phosphor particles.

  Also, a color liquid crystal display device assembly that obtains an image by emitting red light and green light by exciting a phosphor layer with blue light emitted from a light source is known from, for example, Japanese Patent Application Laid-Open No. 2007-4099. is there. A color liquid crystal display device assembly disclosed in this patent publication is a color liquid crystal display device composed of a front panel and a rear panel, and a color liquid crystal display device disposed opposite to the rear panel. A planar light source device having a light source that illuminates from the rear panel side is provided. The phosphor layer is provided on the outer surface of the front panel, for example, or is provided on the outer surface of the rear panel facing the planar light source device.

Japanese Utility Model Sho 63-187120 JP 2002-277870 A JP2002-131552 JP2007-4099

  By the way, in a direct type planar light source device, white light is emitted from a fluorescent lamp. For example, when displaying a red color on a color liquid crystal display device, the white light is passed through a color filter to change the red color from the white light. The process of taking out is performed, and one kind of green and blue constituting white light emitted from the fluorescent lamp is discarded. Therefore, the effective use efficiency of the light flux emitted from the fluorescent lamp (the ratio of the light emitted from the color liquid crystal display device to the color liquid crystal display device out of the light flux emitted from the fluorescent lamp) is low and the light flux is effective. It is desired to further increase the utilization efficiency.

  In the technique disclosed in Japanese Patent Application Laid-Open No. 2007-4099, since the phosphor layer is provided on the outer surface of the front panel, the liquid crystal material is configured by sandwiching a liquid crystal material between the two panels. There is a problem that the distance from the cell to the phosphor layer is long and parallax is likely to occur. Alternatively, the phosphor layer is provided on the outer surface of the rear panel facing the planar light source device, so that light emitted from a certain phosphor layer enters the liquid crystal cell adjacent to the corresponding liquid crystal cell. Crosstalk may occur.

  Accordingly, an object of the present invention is to provide a color liquid crystal display device assembly that has a high effective utilization efficiency of a light beam from a light source, is less likely to cause parallax and optical crosstalk, or can display an image more clearly.

A second primary color light emitting region is provided on the convex lens portion of the second light collecting member, and a third primary color light emitting region is provided on the convex lens portion of the third light collecting member.

  The plano-convex lens has a thickness. Accordingly, when the second primary color light emission region and the third primary color light emission region are provided on the flat surface of the plano-convex lens, the light passes through the second primary color light emission region and the third primary color light emission region and is incident on the flat surface of the plano-convex lens. In the light emitted from the convex lens portion, there is a possibility that parallax occurs or the light spreads due to the thickness of the plano-convex lens. Further, if the light collecting member and the light emitting region are not integrated, a loss due to reflection of light at the interface between the light collecting member and the light emitting region and a radiation loss due to a gap between the light collecting member and the light emitting region occur. There is a fear. However, in the color liquid crystal display device assembly according to the first to fifth aspects of the present invention and the light conversion device according to the first to second aspects of the present invention, the second structure comprising a plano-convex lens is used. A second primary color light emission region and a third primary color light emission region are provided on the convex lens portions of the two light collection members and the third light collection member. Therefore, there is no loss or radiation loss due to light reflection at the interface between the light collecting member and the light emitting region. Furthermore, the cost of parts can be reduced, and it is not necessary to align the light collecting member and the light emitting region when the color liquid crystal display device assembly or the light conversion device is assembled. In addition, if the light collecting member is arranged closer to the observer than the light emitting region, no parallax occurs due to the thickness of the plano-convex lens, and no light spreads, and a Lambertian distribution (half-width) generated in the light emitting region. The light having all solid angle radiation light) can be converted into parallel light or light close to parallel light by the condensing member, so that the light use efficiency can be improved.

  Further, in the color liquid crystal display device assembly according to the first aspect of the present invention, the second primary color light emitting region includes a portion of the first surface of the first substrate corresponding to the second subpixel and a portion of the transparent first electrode. The third primary color light emitting region is disposed between a portion of the first surface of the first substrate corresponding to the third subpixel and a portion of the transparent first electrode. As described above, since the distance from the second subpixel to the second primary color light emitting region and the distance from the third subpixel to the third primary color light emitting region can be shortened, parallax is less likely to occur. In addition, a diffusion region for diffusing the first primary color light that has passed through the first subpixel is disposed between the portion of the first surface of the first substrate corresponding to the first subpixel and the portion of the transparent first electrode. Therefore, an image based on the first subpixel can be clearly displayed.

  Further, in the color liquid crystal display device assembly according to the second aspect of the present invention, the second primary color light emitting region is a portion of the second surface of the first substrate corresponding to the second subpixel and the first of the third substrate. The third primary color light emitting region is disposed between the second surface portion of the first substrate corresponding to the third subpixel and the first surface portion of the third substrate. Has been. In the light conversion device according to the first aspect of the present invention, the second primary color light emitting region is disposed on a portion of the first surface of the support substrate corresponding to the second subpixel, and the third primary color light emitting region is , And a portion of the first surface of the support substrate corresponding to the third subpixel. Therefore, the distance from the second sub-pixel to the second primary color light-emitting area and the distance from the third sub-pixel to the third primary color light-emitting area can be shortened, so that parallax is less likely to occur. Moreover, the diffusion region for diffusing the first primary color light that has passed through the first subpixel is between the second surface portion of the first substrate and the first surface portion of the third substrate corresponding to the first subpixel. Or the diffusion region for diffusing the first primary color light that has passed through the first subpixel is disposed in the portion of the first surface of the support substrate corresponding to the first subpixel. An image based on sub-pixels can be clearly displayed.

  In the color liquid crystal display device assembly according to the third aspect of the present invention, the second primary color light emitting region includes a portion of the first surface of the second substrate corresponding to the second subpixel and a portion of the transparent second electrode. The third primary color light emitting region is disposed between the portion of the first surface of the second substrate corresponding to the third subpixel and the portion of the transparent second electrode. Therefore, the optical crosstalk that light emitted from the second primary color emission region and the third primary color emission region enters a subpixel (liquid crystal cell) adjacent to the corresponding subpixel (liquid crystal cell) is further generated. It can be surely prevented.

  Further, in the color liquid crystal display device assembly according to the fourth aspect of the present invention, the second primary color light emitting region is a portion of the first surface of the third substrate corresponding to the second subpixel and the second surface of the second substrate. The third primary color light emitting region is disposed between the first surface portion of the third substrate corresponding to the third subpixel and the second surface portion of the second substrate. Has been. In the light conversion device according to the second aspect of the present invention, the second primary color light emitting region is disposed on a portion of the first surface of the support substrate corresponding to the second subpixel, and the third primary color light emitting region is , Disposed on the first surface portion of the support substrate corresponding to the third sub-pixel. Therefore, the optical crosstalk that light emitted from the second primary color emission region and the third primary color emission region enters a subpixel (liquid crystal cell) adjacent to the corresponding subpixel (liquid crystal cell) is further generated. It can be surely prevented.

  In the color liquid crystal display device assembly according to the fifth aspect of the present invention, the second primary color light emitting region is disposed on the second surface portion of the second substrate corresponding to the second subpixel. The primary color light emitting region is disposed on a portion of the second surface of the second substrate corresponding to the third subpixel. Therefore, the optical crosstalk that light emitted from the second primary color emission region and the third primary color emission region enters a subpixel (liquid crystal cell) adjacent to the corresponding subpixel (liquid crystal cell) is further generated. It can be surely prevented.

  In addition, the color liquid crystal display device assembly according to the first to fifth aspects of the present invention, and the color liquid crystal display device assembly into which the light conversion device according to the first to second aspects of the present invention should be incorporated. In the above, the first primary color light is emitted from the light source, not the white light. The second primary color light emission region and the third primary color light emission region that emit (emit) the second primary color light and the third primary color light are provided separately from the light source. Therefore, a process of obtaining light of a desired color by passing white light emitted from the light source through a color filter arranged in the color liquid crystal display device is basically unnecessary, and the first light generated by the light source is not necessary. The effective utilization efficiency of the primary color light can be improved, and as a result, the power consumption of the color liquid crystal display device assembly can be reduced. Further, the degree of freedom in selecting the light emitting particles constituting the second primary color light emitting region and the third primary color light emitting region, and the degree of freedom in designing the light emission intensity of the second primary color light emitting region and the third primary color light emitting region can be increased. It becomes possible to obtain a color liquid crystal display device assembly with higher luminous efficiency.

In the surface light source device, a division drive method (partial drive method) is adopted, and a control signal corresponding to a drive signal having a value equal to the drive area maximum value x _U-max in the display area unit is supplied to the pixel. In order to obtain the assumed pixel brightness (light transmittance, display brightness at the first specified value Lt ₁ , second specified value y ₂ ), the light source constituting the planar light source unit corresponding to the display area unit is obtained. If the luminance is controlled by the driving circuit, not only can the power consumption of the planar light source device be reduced, but also the white level can be increased and the black level can be decreased, and a high contrast ratio (on the screen surface of the color liquid crystal display device) can be achieved. Brightness ratio of the all black display portion and the all white display portion, which does not include external light reflection, etc., and the brightness of the desired display area can be emphasized. To improve Door can be.

As described above, each pixel has three types of sub-pixels (sub-pixel [R]), second sub-pixel (sub-pixel [G]), and first sub-pixel (sub-pixel [B]). Subpixels are configured as one set. In the following description of the embodiments, it is assumed that the luminance control (gradation control) of each of the sub-pixels [R, G, B] is 8-bit control and is performed in 2 ⁸ steps from 0 to 255.

The value PS of the pulse width modulation output signal for controlling the respective light emission time of the light emitting diode 623 constituting each planar light source unit also takes a value of 2 ⁸ steps of 0 to 255. However, the present invention is not limited to this. For example, 10-bit control can be performed in 2 ¹⁰ stages from 0 to 1023. In this case, if an 8-bit numerical expression is multiplied by, for example, 4 times Good.

A control signal for controlling the light transmittance Lt of each pixel is supplied from the driving circuit to each pixel. Specifically, a control signal [R, G, B] for controlling the light transmittance Lt of each of the sub-pixels [R, G, B] is supplied to each of the sub-pixels [R, G, B].

That is, in the liquid crystal display device drive circuit 670, the control signal [R, G, B] is generated from the input drive signal [R, G, B], and the control signal [R, G, B] is subpixel. [R, G, B] are supplied (output). Since the light source luminance Y ₂ that is the luminance of the planar light source unit 622 is changed for each image display frame, the control signal [R, G, B] is, for example, the value of the drive signal [R, G, B].

The light transmittance (aperture ratio) Lt of the pixel is controlled. Here, as the values X _R-corr , X _G-corr , and X _B-corr of the control signal [R, G, B] are larger, the light transmittance (aperture ratio) Lt of the sub-pixel [R, G, B]. And the value of the luminance (display luminance y) of the display area corresponding to the subpixel [R, G, B] increases. That is, an image (usually one kind of dot-like) composed of light passing through the sub-pixels [R, G, B] is bright.

The display luminance y and the light source luminance Y ₂ are controlled for each image display frame, each display area unit, and each planar light source unit in the image display of the color liquid crystal display device 610. Further, the operation of the color liquid crystal display device 610 and the operation of the planar light source device 620 within one image display frame are synchronized. Note that the number of image information (images per second) sent to the drive circuit as electrical signals per second is the frame frequency (frame rate), and the inverse of the frame frequency is the frame time (unit: seconds).

  Hereinafter, a driving method of the surface light source device of the split driving method will be described with reference to FIGS. 24, 25, and 27. FIG. FIG. 27 is a flowchart for explaining a driving method of the surface light source device of the split driving method.

Here, a control signal for controlling the light transmittance Lt of each pixel is supplied from the drive circuit to each pixel. More specifically, a control signal [R, G, B] that controls the light transmittance Lt of each of the sub-pixels [R, G, B] is supplied to each of the sub-pixels [R, G, B] constituting each pixel. B] is supplied from the drive circuit 670. Then, in each of the planar light source units 622, driving that is input to the driving circuits 650, 660, and 670 to drive all the pixels (sub-pixels [R, G, B]) constituting each display area unit 612.

It is assumed that the brightness (light transmittance, display brightness at the first specified value Lt ₁ , second specified value y ₂ ) of the pixel (sub-pixel [R, G, B]) is obtained. Further, the luminance of the light source constituting the planar light source unit 622 corresponding to the display area unit 612 is controlled by the planar light source device control circuit 650 and the planar light source unit drive circuit 660. Specifically, the light source luminance Y ₂ may be controlled so that the display luminance y ₂ can be obtained when the light transmittance (aperture ratio) of the sub-pixel is the light transmittance · the first specified value Lt _1. (For example, it may be reduced). That is, for example, the light source luminance Y ₂ of the planar light source unit 622 may be controlled for each image display frame so as to satisfy the following expression (A). Note that Y ₂ ≦ Y ₁ .

Y ₂ · Lt ₁ = Y ₁ · Lt ₂ (A)

[Step-100]
A drive signal [R, G, B] and a clock signal CLK for one image display frame sent from a known display circuit such as a scan converter are input to the planar light source device control circuit 650 and the liquid crystal display device drive circuit 670. (See FIG. 24). The drive signal [R, G, B] is an output signal from the image pickup tube, for example, when y ′ is the amount of light input to the image pickup tube, and is output from, for example, a broadcasting station or the like, and the light transmittance Lt of the pixel. Is a drive signal that is also input to the liquid crystal display device drive circuit 670 and can be expressed as a function of the input light amount y ′ to the power of 0.45. Then, the values x _R , x _G , x _B of the drive signals [R, G, B] for one image display frame input to the planar light source device control circuit 650 constitute the planar light source device control circuit 650. The data is temporarily stored in a storage device (memory) 652. Further, the values x _R , x _G , x _B of the drive signals [R, G, B] for one image display frame input to the liquid crystal display device drive circuit 670 are also stored in the liquid crystal display device drive circuit 670. (Not shown) once stored.

[Step-110]
Next, in the arithmetic circuit 651 constituting the surface light source device control circuit 650, the value of the drive signal [R, G, B] stored in the storage device 652 is read and the (p, q) th [however, , P = 1, q = 1] for driving sub-pixels [R, G, B] in all the pixels constituting the (p, q) -th display region unit 612. The calculation circuit 651 obtains the display area unit internal drive signal maximum value x _U-max that is the maximum value among the values x _R , x _G , and x _B of the drive signal [R, G, B]. Then, the in-display area unit / drive signal maximum value x _U-max is stored in the storage device 652. This step is performed for all m = 1, 2,..., M, n = 1, 2,..., N, that is, for M × N pixels.

For example, when x _R is a value corresponding to “110”, x _G is a value corresponding to “150”, and x _B is a value corresponding to “50”, x _U-max is “150”. Is a value corresponding to.

This operation is repeated from (p, q) = (1, 1) to (P, Q), and the display area unit drive signal maximum value x _U-max in all the display area units 612 is stored in the storage device 652. Remember.

[Step-120]
Then, the control signal [R, G, B] corresponding to the drive signal [R, G, B] having a value equal to the in _- display area unit / drive signal maximum value x _U-max is sub-pixel [R, G, B]. ] Corresponding to the display area unit 612 so that the brightness (light transmittance, display brightness at the first specified value Lt ₁ , second specified value y ₂ ) is obtained by the planar light source unit 622. The light source luminance Y ₂ of the planar light source unit 622 is increased or decreased under the control of the planar light source unit drive circuit 660. Specifically, the light source luminance Y ₂ may be controlled for each image display frame and for each planar light source unit so as to satisfy the following expression (A). More specifically, the luminance of the light emitting diode 623 is controlled based on the equation (B) which is the light source luminance control function g (x _nol-max ), and the light source luminance Y ₂ is set so as to satisfy the equation (A). Control is sufficient. A conceptual diagram of such control is shown in FIGS. 28 (A) and 28 (B). However, as will be described later, it is desirable to perform correction based on the influence of the other planar light source unit 622 on the light source luminance Y ₂ as necessary. It should be noted that these relations regarding the control of the light source luminance Y ₂ , that is, the value of the control signal corresponding to the drive signal having a value equal to the maximum value x _U-max in the display area unit and the drive signal maximum value x _U-max . , Display luminance when assuming that such a control signal is supplied to the sub-pixel, the second specified value y ₂ , the light transmittance (aperture ratio) of each sub-pixel at this time [light transmittance, the second specified value Lt ₂ ], in the planar light source unit 622 such that the display brightness and the second specified value y ₂ can be obtained when the light transmittance (aperture ratio) of each subpixel is the light transmittance and the first specified value Lt ₁ . The relationship between the brightness control parameters may be obtained in advance and stored in the storage device 652 or the like.

Y ₂ · Lt ₁ = Y ₁ · Lt ₂ (A)
g (x _nol-max ) = a ₁ · (x _nol-max ) ^2.2 + a ₀ (B)

Here, the maximum value of the drive signal (drive signal [R, G, B]) input to the liquid crystal display device drive circuit 670 to drive each of the subpixels [R, G, B] is set to x _max . When
x _nol-max ≡ x _U-max / x _max
And a ₁ and a ₀ are constants,
a ₁ + a ₀ = 1
0 <a ₀ <1, 0 <a ₁ <1
Can be expressed as For example,
a ₁ = 0.99
a ₀ = 0.01
And it is sufficient. The value x _R of the drive signals [R, G, B], x G, each x _B, and takes a value of 2 ⁸ steps, the value of x _max is a value corresponding to "255".

  By the way, in the planar light source device 620, for example, assuming brightness control of the planar light source unit 622 of (p, q) = (1, 1), other P × Q planar light source units. It may be necessary to consider the effects from 622. Since the influence of such a planar light source unit 622 from other planar light source units 622 is known in advance by the light emission profile of each planar light source unit 622, the difference can be calculated by back calculation, and as a result, the correction can be made. Is possible. The basic form of calculation will be described below.

The luminance (light source luminance Y ₂ ) required for the P × Q planar light source units 622 based on the requirements of the equations (A) and (B) is represented by a matrix [L _PxQ ]. In addition, the luminance of a certain planar light source unit obtained when only a certain planar light source unit is driven and the other planar light source units are not driven is compared with P × Q planar light source units 622. Obtain in advance. Such luminance is represented by a matrix [L ′ _PxQ ]. Further, the correction coefficient is represented by a matrix [α _PxQ ]. Then, the relationship between these matrices can be expressed by the following equation (C-1). The correction coefficient matrix [α _PxQ ] can be obtained in advance.
[L _PxQ ] = [L ′ _PxQ ] · [α _PxQ ] (C-1)
Therefore, what is necessary is just to obtain | _require matrix [L' _PxQ ] from Formula (C-1). The matrix [L ′ _PxQ ] can be obtained from the inverse matrix operation. That is,
[L ′ _PxQ ] = [L _PxQ ] · [α _PxQ ] ⁻¹ (C-2)
Should be calculated. Then, the light source (light emitting diode 623) provided in each planar light source unit 622 may be controlled so that the luminance represented by the matrix [L ′ _PxQ ] can be obtained. May be performed using information (data table) stored in the storage device (memory) 662. In the control of the light emitting diode 623, the value of the matrix [L ′ _PxQ ] cannot take a negative value, so it goes without saying that the calculation result needs to be kept in a positive region. Therefore, the solution of equation (C-2) may not be an exact solution but an approximate solution.

As described above, the matrix [L _PxQ ] obtained based on the values of the equations (A) and (B) obtained in the arithmetic circuit 651 constituting the surface light source device control circuit 650, and the matrix [α _PxQ ] of the correction coefficient. ], As described above, a luminance matrix [L ′ _PxQ ] when it is assumed that the planar light source unit is driven alone is obtained. Further, based on the conversion table stored in the storage device 652, 0 to Convert to a corresponding integer (value of the pulse width modulation output signal) in the range of 255. Thus, the arithmetic circuit 651 constituting the planar light source device control circuit 650 can obtain the value PS of the pulse width modulation output signal for controlling the light emission time of the light emitting diode 623 in the planar light source unit 622.

[Step-130]
Next, the value PS of the pulse width modulation output signal obtained in the arithmetic circuit 651 constituting the surface light source device control circuit 650 is obtained from the surface light source unit drive circuit 660 provided corresponding to the surface light source unit 622. The data is sent to the storage device 662 and stored in the storage device 662. The clock signal CLK is also sent to the planar light source unit drive circuit 660 (see FIG. 25).

[Step-140]
Then, based on the value PS of the pulse width modulation output signal, the arithmetic circuit 661 determines an on time t _ON and an off time t _OFF of the light emitting diode 623 constituting the planar light source unit 622. still,
t _ON + t _OFF = constant value t _Const
It is. The duty ratio in driving based on pulse width modulation of the light emitting diode is
t _ON / (t _ON + t _OFF ) = t _ON / t _Const
Can be expressed as

Then, a signal corresponding to the _ON time t _ON of the light emitting diode 623 constituting the planar light source unit 622 is sent to the LED drive circuit 663, and based on the value of the signal corresponding to the _ON time t _ON from the LED drive circuit 663. The switching element 665 is turned on for the on time t _ON , and the LED driving current from the light emitting diode driving power source 666 is supplied to the light emitting diode 623. As a result, each light emitting diode 623 emits light for the on time t _ON in one image display frame. Thus, each display area unit 612 is illuminated at a predetermined illuminance.

The states thus obtained are indicated by solid lines in FIGS. 29A and 29B. FIG. 29A shows a drive signal input to the liquid crystal display device drive circuit 670 to drive the subpixels. 29 is a diagram schematically showing a relationship between a value obtained by raising the value of x to the power of 2 (x′≡x ^2.2 ) and a duty ratio (= t _ON / t _Const ). FIG. It is a figure which shows typically the relationship between the value X of the control signal for controlling the light transmittance Lt, and the display brightness | luminance y.

[Step-150]
On the other hand, the values x _R , x _G , x _B of the drive signals [R, G, B] input to the liquid crystal display device drive circuit 670 are sent to the timing controller 671, and are input to the timing controller 671. A control signal [R, G, B] corresponding to the drive signal [R, G, B] is supplied (output) to the sub-pixel [R, G, B]. The values X _R and X _{G of the} control signal [R, G, B] generated by the timing controller 671 of the liquid crystal display device driving circuit 670 and supplied from the liquid crystal display device driving circuit 670 to the subpixels [R, G, B]. , X _B and the values x _R , x _G , x _{B of} the drive signals [R, G, B] are expressed by the following equations (D-1), (D-2), and (D-3). There is a relationship. However, _{b1_R} , _{b0_R} , _{b1_G} , _{b0_G} , _{b1_B} , _{b0_B} are constants. Further, since the light source luminance Y ₂ of the planar light source unit 622 is changed for each image display frame, the control signal [R, G, B] basically sets the value of the drive signal [R, G, B] to 2. A value obtained by performing correction (compensation) based on a change in the light source luminance Y _{2 with} respect to the squared value. That is, since the light source luminance Y ₂ for each image display frame is changed, the light source luminance Y ₂ (≦ Y ₁₎ control signal so that the display luminance · second specified value y ₂ obtained in [R, G, B] Values X _R , X _G , and X _B are determined and corrected (compensated) to control the light transmittance (aperture ratio) Lt of the pixel or sub-pixel. Here, the functions f _R , f _G , and f _B in the expressions (D-1), (D-2), and (D-3) are functions obtained in advance for performing such correction (compensation). is there.

X _R = f _R (b 1 _—R · x _R ^2.2 + b 0 _—R ) (D−1)
X _G = f _G (b 1 _—G · x _G ^2.2 + b 0 _—G ) (D-2)
X _B = f _B (b 1 _—B · x _B ^2.2 + b 0 _—B ) (D-3)

  Thus, the image display operation in one image display frame is completed.

The cross-sectional shape of the continuous convex and concave portions when the light guide plate 710 is cut in a virtual plane perpendicular to the first surface 711 in the first primary color light incident direction to the light guide plate 710 is a triangle. That is, the concavo-convex portion 712 provided on the surface portion of the first surface 711 has a prism shape. The second surface 713 of the light guide plate 710 may be smooth (that is, may be a mirror surface) or may be provided with a blast texture having a diffusion effect (that is, a fine uneven surface).

As the light source, a fluorescent lamp or a semiconductor laser that emits blue light as the first primary color light may be employed instead of the light emitting diode. In this case, 450 nm can be exemplified as the wavelength λ ₁ of the first primary color light corresponding to the first primary color (blue) emitted from the fluorescent lamp, and the green light emitting particle corresponding to the second primary color light emitting particle is, for example, SrGa _The green light emitting phosphor particles made of ₂ S ₄ : Eu may be used, and the red light emitting particles corresponding to the third primary color light emitting particles may be red light emitting phosphor particles made of, for example, CaS: Eu. Alternatively, when a semiconductor laser is used, 457 nm can be exemplified as the wavelength λ ₁ of the first primary color light corresponding to the first primary color (blue) emitted from the semiconductor laser. The corresponding green light emitting particles may be green light emitting phosphor particles made of, for example, SrGa ₂ S ₄ : Eu, and the red light emitting particles corresponding to the third primary color light emitting particles are, for example, red light emitting phosphor particles made of CaS: Eu. And it is sufficient. When a fluorescent lamp is used, a portion of the inner wall of the fluorescent lamp facing the side surface of the color liquid crystal display assembly or the light guide plate (for example, the shape of the inner wall of the fluorescent lamp when cut along a virtual plane perpendicular to the axis is circular) In this case, for example, a fluorescent lamp coated with blue light emitting phosphor particles can be used only on the color liquid crystal display device assembly or the side surface of the light guide plate, for example, a semicircular portion.

In this case, the energy rays emitted from the light source may be ultraviolet rays instead of the first primary color light. Further, the second primary color light emitting particles constituting the second primary color light emitting region and the third primary color light emitting particles constituting the third primary color light emitting region may be light emitting particles excited by ultraviolet rays emitted from the light source.

  Alternatively, for example, a light source that emits the first primary color light and the second primary color light may be used, and the second primary color light emission area may be replaced with a diffusion area or a second primary color light passage area. However, in this case, the light passes through the first sub-pixel and finally passes through the color filter and the second sub-pixel for making the light emitted from the color liquid crystal display device the first primary color light. A color filter is required to make the light emitted from the color liquid crystal display device the second primary color light.
