Display apparatus and vehicle

A display apparatus, comprising:

• a display panel comprising a plurality of sub-pixels, a first power line shared by the plurality of sub-pixels, and a second power line shared by the plurality of sub-pixels, the plurality of sub-pixels each having a first emitting element and a second emitting element;
• a sensing circuit configured to sense electrical characteristics of a sensing area of the display panel through the second power line to output sensing data;
• and
• a power management circuit configured to apply a high potential power voltage and a set current to the first power line in a sensing mode and apply a low potential power voltage for the sensing mode to the second power line in the sensing mode,
• wherein each of the plurality of sub-pixels further comprise a pixel circuit configured to drive the first emitting element in a first viewing angle mode and drive the second emitting in a second viewing angle mode, and
• wherein the power management circuit is configured to apply a positive voltage higher than a low potential power voltage for a display mode as the low potential power voltage for the sensing mode,
• wherein the sensing mode comprises a first viewing angle mode sensing period and a second viewing angle mode sensing period, and
• wherein the power management circuit, in the first viewing angle mode sensing period or the second viewing angle mode sensing period, is configured to generate and apply the second low potential power voltage differently between the first viewing angle mode and the second viewing angle mode.
