Let n be 4 for simplicity. The transistor Q1a
When in the ON state, the transmission line D

At the time of the L level).
a to 81d, while D1 to D4 are transmitting data,
It emits light in pulses. The state that the transistor Q1b immediately after that is ON
The transmission lines D1 to D4 of the control circuit 85
The data sent from the transistor Q1a turned ON
In the case of "1111" which is the same as the
The photodiodes 81a to 81d transmit data to D1 to D4.
While emitting, it emits light in a pulsed manner. On the other hand, when the transistor Q1b is in the ON state,
At some point, the transmission lines D1 to D4 of the control circuit 85
If the transmitted data is “0000”, the light emitting diode
The nodes 81a to 81d do not emit light. When transistor Q1b is ON
The data transmitted from D1 to D4 of the control circuit 85 is
In the case of "1111", data sent from D1 to D4
Is "0000" compared to the time of one data transmission cycle.
The light emitting time of the light emitting diodes 81a to 81d is doubled.
You. Therefore, D1 to D4 of the control circuit 85
If the data to be sent is "1111", D1 to D4
Compared to the case where the data sent from
The diodes 81a to 81d appear bright. Similarly, transistors Q2a, Q2b-Q
When ma and Qmb are ON, the control circuit 85
By selecting the data sent from D1 to D4,
Of the light emitting diodes 82a to 82d,.
The light emitting time can also be controlled, so that the light emitting diodes 82a to 82a to
82d,..., 8 ma to 8 md luminous intensity (or luminous intensity
Quantity) can be controlled. More specifically, for example, the light emitting diode 81
Only a emits more than other light emitting diodes (represented by 81b)
The description will be made on the assumption that the light luminance level is low (1/2).
And when displaying certain characters etc., the light emitting diode
When both 81a and 81b want to emit the same amount of light
In this case, when the transistor Q1a is ON, D1, D
2 as “11”, the light emitting diodes 81a and 81b
Are caused to emit light together. Next, when the transistor Q1b is ON
, D1 and D2 are set to “10” and the light emitting diode 8
Only 1a emits light. By controlling in this way
The light emission time of the light emitting diode 81a is doubled,
It can be made the same as the light emission amount of the light emitting diode 81b. The variation in the light emission luminance level and the like can be reduced more finely.
To solve this, for example, change the pulse width
Q1a ON time and transistor Q1b ON
The time width may be different (in this case,
This will change the output waveform of the circuit. Also the pulse
It can also be said that the ratio of H to L is changed). For example, the time when the transistor Q1b is turned on
