Display
The 6.6-inch IPS LCD screen is a central feature of the TCL 503, striking a balance between size and usability. The large display area, complemented by an 84.6% screen-to-body ratio, ensures that users have ample viewing space for media consumption and daily tasks. The resolution of 720 x 1612 pixels delivers decent clarity, though not exceptionally high, which is expected in this price range. The screen's brightness, rated at 350 nits typical, provides adequate visibility under most lighting conditions, though it may struggle under direct sunlight.
