I have read that the ESP-32 will have a “Capacitive touch sensor” and an “LCD interface”. What exactly is meant by that?
Could I solder an old cellphone touch screen directly to it, without SPI or i2c?
What is the “Capacitive touch sensor” and the “LCD interface”

The LCD interface is basically an 8, 16 or 24-bit parallel interface connected to DMA that makes it very fast to upload data to parallel LCDs or other peripherals. (It's actually part of one of the I2S ports.)

See lessTouch sensor is for buttons like you see on a microwave keypad. LCD interface could be through SPI or maybe HS1 8-bit interface.
