Please refer to FIG. 1 and FIG. 2. In this embodiment, the display light beam L emitted from the light source 120 is coupled from the first end 110 a to the optical fiber 110 and transmitted. Naturally, when the intensity of the display beam L is fixed, for the same optical fiber 110, the intensity of the display beam L emitted by the light leakage point 112 that is farther away from the first end 110a is weaker. This phenomenon is not conducive to the optical fiber display 1000. Display effect. However, this phenomenon can be compensated by adjusting the intensity of the display light beam L emitted from the light source 120. For example, in this embodiment, the plurality of light valves 210 include the first to mth light valves (for example, the first Multiple light valves 120-1 to 120-3); the intensity of the multiple light sources 120 when the mth light valve (eg, the third light valve 120-3) is opened is greater than the (mn) th light valve When the valve (eg, the first light valve 120-1) is opened, the intensity of the multiple light sources 120, m (eg, 3) is a positive integer greater than or equal to 2, and n (eg, 1) is a greater than or equal to 1. A positive integer, and m is greater than n. In short, when the light valve 120 that is further away from the light source 120 is opened (that is, when a plurality of light leakage points 112 in a row farther from the light source 120 needs to play a display role), the intensity of the display light beam L emitted by the light source 120 is stronger. Therefore, even if the light leakage point 112 of a certain column is far away from the light source 120, when a light valve 210 overlapping the light leakage point 112 of the column is opened, the intensity of the display light beam L emitted by the light leakage point 112 of the column may still be equal to Or it is close to the intensity of the display light beam L emitted from the light leakage point 112 near a column of the light source 120, which is helpful for the display effect of the optical fiber display 1000 (for example, uniformity of screen brightness).

For example, in this embodiment, the plurality of touch light sources 120 'can constantly emit a touch light beam L'. In other words, all the light leakage points 112 can emit the touch beam L 'at all times. When each light valve 210 is opened, the multiple light detectors 300 will detect the intensity of multiple touch beams L 'from multiple second ends 110b of multiple optical fibers 110 at a time to obtain a corresponding light valve. A touch beam intensity group at 210 on time, which is received and recorded by the processing unit 400. For example, in this embodiment, the first light valve 210-1, the second light valve 210-2, and the third light valve 210-3 are respectively connected at the first time, the second time, and the third time. When the time is turned on, the plurality of light detectors 300 respectively detect the intensities of the plurality of touch beams L ′ from the plurality of second ends 110b at the first time, the second time and the third time, so as to obtain the corresponding first A first touch beam intensity group at a time, a second touch beam intensity group at a second time, and a third touch beam intensity group at a third time.

When an object (for example: a finger) touches the fiber optic display 1000A and the light valve 210 (for example, the third light valve 210-3) located in the touched area is opened (for example, the third time), the object (for example: the finger ) The touch beam L ′ leaked from the light leakage point 112 is reflected back to the optical fiber 110, so the corresponding touch beam received by the light detector 300 (for example, a light detector 300 on the far right of FIG. 8) L 'intensity will be stronger. By comparing the difference between the plurality of touch beam intensity groups detected by the plurality of light detectors 300 during the multiple periods when the plurality of light valves 210 are each opened and the reference touch beam intensity group, the processing unit 400 can Determine the touch position (for example: the pixel area P in the 5th and 8th rows). In this embodiment, the reference touch beam L ′ intensity group is, for example, when the optical fiber display 1000A is not touched (that is, the touch beam L ′ emitted by all light leakage points 112 is not reflected by the external object back to the optical fiber 110. Time), a touch beam intensity group detected by the plurality of light detectors 300.

The optical fiber display 1000B also has a touch function. The difference between the optical fiber display 1000B and the optical fiber display 1000A is that the optical fiber display 1000B does not need to be additionally provided with a touch light source 120 ', and the touch light beam L' can be provided by a light source 120 capable of emitting a display light beam L. Furthermore, in this embodiment, the light source 120 can emit the display light beam L and the touch light beam L 'respectively during the alternate display time and touch time to complete the display and touch point detection operations.
