Abstract

A current sensing type sensing unit comprising: a current sink circuit (SINK) that is connected to a sensing line (14B) and reduces a pixel current (Ip) fed via the sensing line (14B) by an amount equal to a sink current (Is); a current integrator (CI) that is connected to the sensing line (14B) and accumulates an adjusted current (Ip-Is), which equals the pixel current (Ip) minus the sink current (Is), to produce an integrated value (Vsen); a sampling part (SH) that samples and holds the integrated value (Vsen); and an analog-to-digital converter (ADC) that performs analog-to-digital conversion of the integrated value (Vsen) from the sampling part (SH) to produce a digital sensed value (SD).
