The display panel 120 is disposed above the backlight module 11 . The printed circuit board 140 is connected to the display panel 12A by a flexible circuit board 130. Since the flexible circuit board 130 is a soft material, the printed circuit board 140 is placed on one side of the backlight module π〇. The printed circuit board 140 has a second screw hole 164, and the first module screw hole 162' has a first screw hole 162' for aligning with the second screw hole ι64 of the printed circuit board 140, and the printed circuit board 140 is locked by the screw 166. The backlight module 11〇. In the process of aligning the printed circuit board 140 with the backlight module 11, the printed circuit board 140 may sag due to its own weight without applying external force or support. Therefore, if the printed circuit board 14 〇 and the backlight module 11 锁 are manually locked, the second screw hole 164 of the printed circuit board 140 is not aligned with the first screw hole 162 of the backlight module 11 对. . In addition, in the prior art, the first screw hole 164 of the printed circuit board 140 and the first screw hole 162 of the backlight module no are pre-aligned and supported by the auxiliary holding mechanism to facilitate the screw 166. The printed circuit board 14 is coupled to the backlight module 110. After the screw 166 is locked, the auxiliary holding mechanism is released. Since the prior art is to manually align the position or to assist the holding mechanism to position the printed circuit board 14 and the backlight module 110, a longer time is required. In addition, due to the high cost of the auxiliary holding mechanism, the production cost of the display is relatively advanced.

In addition, the backlight module 210 includes a positioning pin 252' and the printed circuit board 240 includes a positioning hole 254. The locating holes 254 are used in conjunction with the positioning pins 252 to position the printed circuit board 240 on the backlight module 210. Please refer to FIG. 2A and FIG. 2B at the same time. FIG. 2B is a side view showing the structure of the backlight module 210 and the printed circuit board 240 in FIG. 2A. The shape of the positioning pin 252 is a taper, that is, the cross section of the positioning pin 252 is gradually reduced from the bottom to the top. Therefore, the top section A of the positioning pin 252 is smaller than and included in the bottom section B of the positioning pin 252. Taking the trapezoidal positioning pin 252 as an example, the side 256 of the positioning pin 252 has an oblique angle 0 with a vertical line L perpendicular to the bottom of the positioning pin 252. This inclination angle 0 is not suitable. • It is too large, so that the positioning hole 254 can be combined with the positioning pin 252 to achieve an appropriate positioning effect. Additionally, the cross-section C of the locating aperture 254 on the printed circuit board 240 is greater than and includes the top cross-section A of the locating pin 252 such that the locating aperture 254 is sufficient to fit within the locating pin 252. Moreover, the section C of the positioning hole 254 is smaller than and included in the bottom section B of the positioning pin 252, so as to avoid the positioning effect being affected by the cross section c being too large when the positioning hole 254 is combined with the bottom of the positioning pin 252. Since the top section a of the clamping pin 252 is smaller than the bottom section B, even if the center point of the positioning hole 254 is not completely aligned with the center point of the positioning pin 252, the positioning hole 254 is located as long as the top of the positioning pin 252 enters the clamping hole 254. The bottom of the positioning pin 252 can be coupled to the bottom of the positioning pin 252 via the guiding portion 256 of the positioning pin 252 to position the printed circuit board 240 on the backlight module 210. In this way, the first screw hole 262 can be aligned with the second screw hole 264, so that the printed circuit board 240 and the backlight module 21 can be locked together by the screw 266. As described above, the display 2 of the present invention has a positioning pin 252 in the backlight module 21, and the positioning hole 254 is provided as an example. However, the display 200 of the present invention may also be a backlight module. The set 210 has locating holes and the printed circuit board 240 has a mortise pin. Or, as shown in FIG. 3A, FIG. 3A is a side view showing a structure in which the backlight module 21A of the display panel 209 has a positioning pin 258 and the printed circuit board 24A has a positioning groove 270 according to a preferred embodiment of the present invention. The positioning pin 258 is coupled to the positioning groove 2 in a snap-fit manner.
