It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if the device in one figure is turned over, elements described as being on the "lower" side of other elements will be oriented on the "upper" side of the other elements. Therefore, the exemplary term "lower" may include an orientation of "lower" and "upper", depending on the specific orientation of the drawing. Similarly, if the device in one figure is turned over, elements described as "below" or "beneath" other elements will be oriented "above" the other elements. Thus, the exemplary terms "below" or "below" can include an orientation of above and below.

As used herein, "substantially", "similar", or "approximately" includes the stated value and the average value within the acceptable deviation range of the specific value determined by a person of ordinary skill in the art, taking into account the measurement in question and the A certain amount of measurement-related error (ie, the limitation of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%.

In addition, the overlap of two adjacent display panels 140 may be located on the fixing frame 110.

For another example, when the spliced display 100 is in the extended state shown in FIG. 1B, the sides of two adjacent display panels 140 can be arranged side by side, so that the display panel 140 can display The pictures can be spliced with each other. In addition, the side edges of two adjacent display panels 140 may be located on the fixing frame 110 side by side.
