Referring to FIG. 3A, the pixel unit 300a of the present embodiment is similar to the pixel unit 200a of the first embodiment, but the main difference is that the blue display area B in the pixel unit 300a is displayed in addition to yellow. The area Y is further adjacent to the yellow display area Y. In the present embodiment, the sum of the areas of the blue display area B and the yellow display area Y in the halogen unit 300a is twice the area of the red display area R or the green display area. Further, the blue display area B and the yellow display area Y in this embodiment constitute a rectangular area. Referring to FIG. 3B, the pixel unit 300b of the present embodiment is similar to the pixel unit 200b of the first embodiment, but the main difference between the two is that the white display area W in the pixel unit 300b is apart from the yellow display area. In addition to Y, it further surrounds the yellow display area Y. In the present embodiment, the sum of the areas of the white display area W and the yellow display area Y in the halogen unit 300b is the area of the red display area R, the green display area or the blue display area B. Further, the white display area W and the yellow display area Y in this embodiment constitute a rectangular area. [Experimental Example] Figs. 4 and 5 show experimental data of the present invention. As can be seen from FIG. 4, when the area of the yellow display area Y is the same as the area of the red display area R, the area of the green display area G, and the area of the blue display area B, the white color coordinates displayed by the display unit are (0.313, 0.359); when the area of the yellow display area Y is 80% of the area of the red display area R or the green display area G, and the blue display area

When the area of the yellow display area Y is 20% of the area of the red display area R or the green display area G, and the area of the blue display area B is 180% of the area of the red display area R or the green display area G, the display unit The white color coordinates shown should be (0.240, 0.219). As can be seen from the above, whenever the area of the yellow display area Y is increased by 20% and the area of the blue display area B is decreased by 20%, the X-color coordinates displayed by the display unit are reduced by 0.011 on average, and the y-color coordinates are lowered. 0.024, and then move in the direction of the blue color coordinates. Referring to the right side of Fig. 4, regardless of the area ratio of the yellow display area Y and the blue display area B, the yellow color coordinates displayed by the display unit are not significantly offset.
從圖5可知，當白色顯示區W的面積與紅色顯示區R 的面積、綠色顯示區G的面積以及藍色顯示區B的面積相 同時，顯示單元所顯示出的白光色座標為(0.313, 0.359); 當白色顯示區W的面積為紅色顯示區R或綠色顯示區G 201217875As can be seen from FIG. 5, when the area of the white display area W is the same as the area of the red display area R, the area of the green display area G, and the area of the blue display area B, the white color coordinates displayed by the display unit are (0.313, 0.359); When the area of the white display area W is the red display area R or the green display area G 201217875

When the white color color object of the single display 4 is displayed, the area of the W area is the area of the red display area R or the green display area g ^ 40% ' and the area of the yellow display area Y is the red display area or the green area When the area of the display area G is 6 G%, the white light color seat (0.259'0.2 illusion) displayed by the display unit and the area of the white display area w is the red display area: or 2G% of the area of the green display area G, When the area of the yellow display area γ is 80% of the area of the red display area R or the green display area G, the white light color coordinates displayed by the display unit should be (〇.241, 〇.219). As can be seen from FIG. 5, whenever the area of the white display area w is increased by 20%, and the area of the yellow display area Y is decreased by 20%, the X color coordinate displayed by the display unit is lowered by 0.018, and the y color coordinate is lowered by 0.035. And then move in the direction of the blue color coordinates. Referring to the right side of Fig. 5, regardless of the area ratio of the white display area w and the blue display area B, the yellow color coordinates displayed by the display unit are not significantly offset. In addition to considering whether the yellow color coordinates have a significant offset phenomenon, the present invention can further consider whether the yellow pupil surface is distorted. Generally, the parameter for determining whether the yellow pupil surface is distorted is Delta E, and the definition of Delta E is sqrtlXLi. -I^+h-ay+^-bJ2], where (Lh al5 bi) is the yellow display area 201217875
